A thousand liters of seawater can contain up to 8.3 million particles of microplastics. Until now, identifying these very small particles has been difficult—usually they are only detected once they have accumulated in the bodies of fish. A method developed at VTT utilizes nanocellulose structures for early particle identification. Nanocellulose would allow particles to be captured even before they enter waterways.


The properties of nanocellulose films and hydrogels support the identification and capture of very small microplastic particles.

"Nanocellulose has a mesh-like, porous structure and a large BET surface area. In the water, powerful capillary forces are generated in this structure, allowing particles to be transported inside the mesh and bound there," says Research Professor Tekla Tammelin from VTT.

The method provides a way to catch microplastic particles of a size that the human eye cannot detect. These are particles with a diameter of only 100 nanometers.

"Nanocellulose structures can be used to identify and analyze these particles and to obtain information about their behavior at an earlier stage. We can determine the concentration of particles in water and analyze, for example, whether particles are released into drinking water from plastic bottles."

Next step: filtration methods

The identification of microplastic particles with nanocellulose structures has been developed at VTT as part of the FinnCERES flagship project, which is exploring new bio-based material solutions. The next step could be to develop new and inexpensive filtration solutions utilizing the method.

"New filtration solutions would allow particles to be captured where they are generated. The solutions could be utilized, for example, in laundry, where microplastic particles are released from fleece clothing and other synthetic fibers. Similarly, we could develop filtration methods for any industry where there is a risk of microplastics being generated and released into waterways."

Rochester Institute of Technology scientists have developed the first three-dimensional mass estimate to show where microplastic pollution is collecting in Lake Erie. The study examines nine different types of polymers that are believed to account for 75 percent of the world's plastic waste.

Plastic behaves differently in lakes than in oceans; previous studies on both have indicated the levels of plastic pollution found on the surface are lower than expected based on how much is entering the water. While massive floating "islands" of accumulated plastic waste have been found in oceans, previous studies have indicated the levels of plastic pollution found on the surface of Lake Erie are lower than expected based on how much is entering the water.

The new RIT estimate for the 3-D mass—381 metric tons—is more than 50 times greater than the previous estimates at the surface. The study also generated the first estimate of how much plastic is deposited on the bottom of the lake. It accounts for the unique properties of different types of plastics and shows that the three polymers with the lowest density—polyethylene, polypropylene and expanded polystyrene—accumulate on the surface of the lake while the other six polymers were concentrated in the sediment.

"Previously there was a focus on plastics modeled as neutrally buoyant for the most part in the beginning of plastics modeling," said Juliette Daily, a mathematical modeling Ph.D. student and author of the study. "In reality, plastic is probably almost never neutrally buoyant. It's probably always positively or negatively buoyant, which really changes how the particles behave."

The study shows other interesting patterns, such as plastic particles accumulating more heavily on the eastern shore of the lake, perhaps from the current moving predominantly west to east. This means that pollution could be pushed disproportionately to areas like Buffalo, N.Y. The authors hope other researchers will continue to build on this research and explore how factors like beaching can further explain where plastic particles end up.

"Trying to understand where plastic is going is important for people looking at mitigation or prevention and will be important for understanding what the most likely impacted areas are," said Matthew Hoffman, associate professor in the School of Mathematical Sciences and co-author of the paper. "Looking at things in the sediment or getting an idea of what is down in the lower levels of the lake will give us a better idea of what concentrations there are and what possible exposure levels are to this ecosystem."

The study is published in the May 2020 edition of the Marine Pollution Bulletin.

Adsorbent material developed from PET bottles for the removal of antibiotics from water

by National Research Council of Science & Technology

The KIST research team observed magnetic porous carbon composite materials in the transmission electron microscope. Researchers tested the efficiency of the porous carbon composite in terms of its ability to adsorb "tetracycline," or the antibiotic used to treat bacterial infections, from the water. Tests showed that the newly developed material was able to remove 100% of the tetracycline in about 90 minutes under general water conditions (pH 6), with an adsorption rate of 671.14 mg/g, which is a rate superior to that of previously developed adsorbents. In order to assess the reusability of the porous carbon composite, the adsorption-desorption process was conducted five times. Even after repeated use, the material maintained 90% of its adsorption properties, indicating a high degree of stability and wide applicability for water treatment.

South Korea, with its high antibiotic use, is categorized as a country at high risk of the emergence of multi-drug-resistant bacteria, or so-called "super bacteria." According to the Ministry of Environment, antibiotic substances have been detected at livestock wastewater treatment facilities, sewage treatment plants and in rivers.

The Korea Institute of Science and Technology announced that a research team, led by researchers Jung Kyung-won and Choi Jae-woo, at KIST's Water Cycle Research Center, has developed a high-efficiency, adsorbent material using PET waste bottles. The new material is expected to help solve the problem of environmental toxins and antibiotic-resistant bacteria which are caused by leaks of antibiotics into water.

Currently, the most well-known method of effectively removing antibiotics from water uses porous carbon composite, synthesized by pyrolyzing metal-organic frameworks (MOF). Porous carbon composites adsorb antibiotics in the water, thereby removing them. However, since the organic ligand generally used to synthesize MOF is very expensive, the cost is a major obstacle to this method's widespread, practical application through mass production.

In order to develop a more cost-effective solution, the KIST research team turned its attention to the PET bottles that people use in their everyday lives. PET is a high-molecular compound obtained by polymerizing ethylene glycol and terephthalic acid, the latter of which is used as organic ligand for the syntheses of MOF. The KIST research team extracted high-purity organic ligand from PET waste bottles and used it to synthesize a high-efficiency adsorbent material that could effectively remove antibiotics from water in an environmentally and economically beneficial way.

During the development of this adsorbent material, an alkaline hydrolysis process was used to induce a neutralization reaction, resulting in the production of a high-purity terephthalic acid. To maximize the efficiency of the alkaline hydrolysis process, the research team incorporated an ultrasound-assisted phase transfer catalyst process. By optimizing this process, the team was able to successfully extract 100% high-purity terephthalic acid, which they then used to develop a porous carbon composite. Iron-based MOF was used as a precursor in order to impart magnetism to the adsorbent material. In this way, the team was able to develop an eco-material that can be easily separated from the mixture after the adsorption process, using an external magnetic field.


The KIST research team tested the efficiency of the porous carbon composite in terms of its ability to adsorb "tetracycline," or the antibiotic used to treat bacterial infections, from the water.

Even after repeated use, the material maintained 90% of its adsorption properties, indicating a high degree of stability and wide applicability for water treatment.

Dr. Jung Kyung-won at KIST said, "This porous carbon composite is applicable to a wide range of water treatment areas as it uses waste plastics to prevent environmental pollution and maintains its high adsorption properties even after repeated use."

KIST's Dr. Choi Jae-woo said, "The porous carbon composite developed through this research is applicable to various fields, ranging from eco-materials to energy materials, and I expect that it will soon be highly regarded as a value-added eco-material."

The best material for homemade face masks may be a combination of two fabrics

by American Chemical Society

In the wake of the COVID-19 pandemic, the U.S. Centers for Disease Control and Prevention recommends that people wear masks in public. Because N95 and surgical masks are scarce and should be reserved for health care workers, many people are making their own coverings. Now, researchers report in ACS Nano that a combination of cotton with natural silk or chiffon can effectively filter out aerosol particles—if the fit is good.

SARS-CoV-2, the new coronavirus that causes COVID-19, is thought to spread mainly through respiratory droplets when an infected person coughs, sneezes, speaks or breathes. These droplets form in a wide range of sizes, but the tiniest ones, called aerosols, can easily slip through the openings between certain cloth fibers, leading some people to question whether cloth masks can actually help prevent disease. Therefore, Supratik Guha at the University of Chicago and colleagues wanted to study the ability of common fabrics, alone or in combination, to filter out aerosols similar in size to respiratory droplets.
The researchers used an aerosol mixing chamber to produce particles ranging from 10 nm to 6 μm in diameter. A fan blew the aerosol across various cloth samples at an airflow rate corresponding to a person's respiration at rest, and the team measured the number and size of particles in air before and after passing through the fabric. One layer of a tightly woven cotton sheet combined with two layers of polyester-spandex chiffon—a sheer fabric often used in evening gowns—filtered out the most aerosol particles (80-99%, depending on particle size), with performance close to that of an N95 mask material. Substituting the chiffon with natural silk or flannel, or simply using a cotton quilt with cotton-polyester batting, produced similar results. The researchers point out that tightly woven fabrics, such as cotton, can act as a mechanical barrier to particles, whereas fabrics that hold a static charge, like certain types of chiffon and natural silk, serve as an electrostatic barrier. However, a 1% gap reduced the filtering efficiency of all masks by half or more, emphasizing the importance of a properly fitted mask.

A study looks at how to disinfect your mask at home

an Yan, Columbia University

A new study suggests that disposable surgical masks can be disinfected with heat multiple times without harming their effectiveness. A homemade plastic nose clip, used here, may add another layer of protection. Credit: Beizhan Yan

Due to the unknown numbers of asymptomatic people infected with the SARS-CoV-2, the Centers for Disease Control and Prevention has recommended that all citizens wear face coverings when in public. More recently, some states have mandated face coverings. Many people are wearing homemade coverings, but these mandates potentially increase demand for medical face masks, exacerbating shortages for first responders and medical staff.

One way to to extend the supply of disposable masks is to disinfect them and reuse them. We have just published a paper in the Journal of the International Society for Respiratory Protection that looks into whether disposable masks can be disinfected by heating them without compromising their effectiveness. We also compared the effectiveness of medical-grade masks with homemade ones, and looked into the feasibility of improving masks with homemade nose clips.

Prior work by others on disinfection of disposable masks has shown that heating for 30 minutes at 158 degrees F (70 C) or above can effectively destroy SARS, influenza and the novel SARS-CoV-2 coronavirus. This can be done in a home oven. As such, we did no testing with viruses. Instead we focused on whether repeated heat disinfection affected how well the masks worked for removing particles in the same size range as coronavirus.

To do this, we put masks onto mannequin heads, and rigged the heads to "breathe" through their noses and mouths, using a vacuum pump. We then exposed the mannequins to black carbon (i.e, soot) from a kerosene lamp, which generates particles that overlap in size with those of the coronavirus. We determined filtration efficiency by comparing black-carbon levels on both sides of the masks worn by the mannequins. We did this with two brands of disposable N95 respirators and one brand of disposable surgical mask, as well as with one design of homemade face covering. We tried this out repeatedly, and in a variety of ways.

First, to measure the maximum filtration efficiency and resilience of the disposable masks, each disposable mask type was tested while taped or modified to tightly fit a plastic mannequin's face when new, and again after each heating cycle. We found that one N95 brand (3M) and a surgical mask (HSl brand) stood up to the 10 cycles of heat disinfection and reuse, with no reduction in performance. Filtration efficiency was greater than 95 percent over all 10 cycles for N95 respirators, and greater than 70 percent for surgical masks. (In contrast, we found that the nose-pad of another N95 brand, the Moldex, was unable to withstand multiple cycles of being put on and off the mannequin, whether or not it was heated in between uses.)


These tests show the maximum filtration efficiency possible, but they are not representative of how people normally wear masks, where the fit can be much looser. So, for a second set of tests, we obtained a head form covered in soft silicone to mimic the pliability of the human face. We then assessed the effectiveness of the masks as they are commonly worn, by simply putting the elastic straps around the head or ears without additional tightening. As expected, the filtration efficiency of all the disposable masks decreased substantially, to around 40 percent. This confirms that the effectiveness of such masks relies upon a tight fit, and this may be hard for many people to achieve.

We also tested the filtration efficiency of three homemade cloth coverings made following instructions on the CDC website. We made one from a cotton dress, one from a cotton sweater, and the third from polyester cloth. All three were worn in a normal mode on the silicone head form as directed by the CDC. The filtration efficiency of the cotton homemade cloth coverings in normal use was 55 percent, while the polyester covering came in at near 40 percent—about the same as loosely fitted medical-grade masks. This suggests that homemade cotton masks might actually work better than loosely fitted disposable masks, while polyester might be about the same.


We heated up the homemade masks for disinfection, which appeared to not affect the filtration efficiency. The CDC recommends washing and drying such coverings at home and we anticipate negligible effects on efficiency from this as well. When disinfecting your masks at home, we recommend you to place masks in an oven bag or a pressure cooker during heating, rather than directly put masks inside of the oven (see the instruction video below for details).
Finally, to see if we could improve the fit for the public, we designed a process that uses heat-moldable plastic strips to make homemade customized nose clips molded to an individual's face. By adding the customized nose clip to a normally worn disposable mask on a silicone head form, the filtration efficiency of the 3M N95 returned to greater than 95 percent, and the filtration efficiency of the surgical masks was measured at 88 percent. The nose clips passed two five-hour wearing tests for comfort. But due to the use of heat moldable plastic, the customized nose clips cannot be disinfected with heat; rather, they must be disinfected by soaking in solutions of alcohol or bleach.

This work has certain limitations. For one, our tests were all done under static conditions at a constant flow rate of air similar to how an adult breathes when sitting. We did not take into account the increase in breathing, nor the reduction in fit that can occur when someone is talking or active.

Our study is just one of many looking into how masks may be disinfected and reused. Others have been carried out or are in progress using not only heat, but ultraviolet light, vaporized hydrogen peroxide, or soaking in ethyl alcohol or bleach solutions. Most of these are aimed at medical personnel using specialized equipment. The soaking methods have been shown to reduce the effectiveness of certain types of N95 masks. Ours is a relatively modest effort aimed at everyday usage. Far more work needs to be done, but everything we know so far suggests that wearing almost any kind of mask in public is better than nothing; that a tight fit is best; and that, with certain limits, many types of masks can be reused outside of medical settings.

Warming climate undoes decades of knowledge of marine protected areas
by Lancaster University APRIL 24, 2020

Climate change and warming seas are transforming tropical coral reefs and undoing decades of knowledge about how to protect these delicate and vital ecosystems.


Many of the world's coral reefs are seeing biodiversity plunge in the face of repeated coral bleaching events.

Protected areas, called marine reserves, are an effective and long-established tool in the conservation toolbox. Marine reserves have been used for decades to enhance biodiversity and fish biomass by preventing damage and over-exploitation by fishing.

However, a new study highlights that tropical coral reef marine reserves can offer little defence in the face of climate change impacts. And the changes that are being observed will force scientists, conservationists and reserve managers to rethink the role these protected areas can bring.

"Climate change is so fundamentally changing the structure and composition of coral reef ecosystems, that the way the ecosystem functions and responds to common management and conservation approaches needs to be carefully re-evaluated," explains Professor Nick Graham of Lancaster University and lead author of the study. "The rules we have come to rely on, no longer apply."

Bleaching occurs when seas become too warm, causing corals to expel their colourful algae. This disrupts the ecosystem and reduces the availability of food and shelter for many fish species.

Some coral reefs are able to recover over time, while others are transformed and become dominated by seaweed.

The new study, published in the journal Nature Communications, focused on reefs and marine reserves in Seychelles. Coral reefs in Seychelles were badly affected by a bleaching event in 1998, when around 90% of the coral died. Scientists used data from 21 reefs over a 20-year time period, spanning the 1998 bleaching event, to explore how reefs have changed and how this has affected the role of marine reserves.

Professor Graham explains: "Our long-term records of Seychelles' coral reefs show that before the bleaching event marine reserves contained high coral cover, a very biodiverse range of fish, and high biomass of carnivorous and herbivorous fish.


"Following the bleaching event, the role of the marine reserves changed substantially. They no longer supported higher coral cover compared to adjacent fished areas, and their role in enhancing biodiversity decreased. Plant-loving fish, such as rabbitfish and parrotfish, dominated fish communities. This was the case for reefs where corals were recovering, as well as reefs transformed and dominated by seaweed."

Reduced numbers of carnivorous predators, such as grouper and snapper species, show reserves are much less effective at protecting the tops of food webs in the years following bleaching events. These population drops are likely due to fewer fish for them to prey on after the loss of coral reef structures.

Dr. Shaun Wilson, of the Department of Biodiversity, Conservation and Attractions in Western Australia, a co-author on the study, said: "Despite these climate-driven transformations, marine protected areas still have a role to play in ocean conservation. It is encouraging that marine reserves continue to protect some species, especially when these species are critical for local fisheries."

Gilberte Gendron of the Seychelles National Parks Authority, adds: "Although these reordered marine reserves are less biodiverse, they are still important to maintain. This is because, when compared to openly fished areas, they still protect higher levels of fish biomass of species that are important to our local fisheries. For example, the protected herbivorous fish can spill out into openly fished areas and help support adjacent fisheries."

If the goal is to protect biodiversity then it may be better to target new marine reserves around those coral reefs where the rate of warming is slowest, or those where recovery from bleaching is more likely.

While the scientists say marine reserves still have an important role to play in protecting fish biomass, they call in their paper for urgent reductions in global greenhouse gas emissions, as well as other pressures such as poor land practices that input nutrients and pollutants to coastal waters, to protect tropical coral reefs.

Making wind power more predictable


by Gabe Cherry, University of Michigan

A computer model that uses existing weather data to map long-term wind patterns at prospective wind turbine sites could help energy companies set up wind turbines more quickly and less expensively. The model eliminates the need to deploy dedicated wind monitoring stations. It could also make wind energy more reliable by enabling networks of turbines that are strategically placed to generate a more consistent stream of energy.


A team led by U-M assistant professor of industrial operations and engineering Eunshin Byon developed the model. We sat down with Byon recently to learn more about her work.

Is siting wind turbines really more complicated than just finding a windy spot?

As wind becomes a more and more important part of our energy supply, finding a windy spot will no longer be enough. We'll need to predict how the wind patterns at a given site will vary from day to day and month to month.

Currently, the only way to get a year of wind data for a specific site is to set up a meteorological station on that site and collect data for a year. That's not practical from a financial or time standpoint, especially as deployment of wind turbines continues to ramp up. And we believe we've found a better way.

Why is it important to have longer-term data about wind patterns?

The wind isn't always blowing in a given spot, but it's always blowing somewhere. If power companies can predict where and when the wind will blow, they can design their networks so that, when one turbine is likely to be idle, another is likely to be generating power

How does your method measure wind patterns without setting up a measuring station?

Instead of measuring wind patterns at the actual wind turbine site, we've used existing data from automated weather stations called mesonets. We've built a computer model that can use their data to estimate wind patterns at any location within a radius of about 22 miles from the mesonet station.

Tell me more about these Mesonet stations. What are they used for today?

Mesonets are networks of relatively simple, automated weather monitoring stations that are used to monitor localized weather patterns. They're spread all over the country and generally run by universities and other public entities. Michigan State University operates one here in Michigan. For our study, we used data from the West Texas Mesonet, which is operated by the National Wind Institute at Texas Tech University.

How accurate is your model compared to an actual monitoring station?

We found that our model accurately measured wind speed to within one meter per second. So it's very accurate. We determined those figures by setting up a dedicated monitoring station at a test site and compared its actual wind data to the estimated data from our model for the same site.

Does generating a model like this require a lot of computing power?

A model that predicts wind patterns at a single site is not very computing-intensive and can be done on an ordinary laptop.

What else could this technology be used for?

These mesonet stations collect a variety of weather data, and that could be useful for modeling other properties, like solar radiation levels. That could help solar energy installers site their installations more effectively as well. Solar power is growing even faster than wind right now, so that could be very important.

What are the next steps for this research?

We're looking at adapting our models to use Numerical Weather Prediction data—this is the larger-scale data that's used to generate the weather forecasts we all rely on. That data could enable us to get predictions of more types of patterns that are even more accurate and available in more areas.

The work is detailed in a paper titled "Probabilistic Characterization of Wind Diurnal Variability for Wind Resource Assessment." It is published in the January 2020 issue of IEEE Transactions on Sustainable Energy.

Energy efficiency could prevent the need to build up to 50 power plants in Indonesia

by Virginie Letschert, and Michael McNeil, The Conversation
Saving energy can save money and the environment. Credit: Mohamed Hassan/ Pixabay
Indonesia's electricity demand is growing rapidly. Robust economic growth combined with unprecedented urbanisation and industrialisation are driving this demand.

Based on the Ministry of Energy and Mineral … esources statisctics, daily peak electricity demand is also increasing rapidly. It is officially projected to double by 2030 to over 160 gigawatts (GW).

Domestic appliances and equipment, such as air conditioners (ACs), lighting, refrigerators and TVs, will lead energy demand in Indonesia by 2030, representing as much as 70% of the load during peak time at 8pm.

To meet the rising demand, Indonesia plans to build 87GW of additional power – the equivalent of 175 medium-size (500 megawatt) power plants—by 2030.

However, our research identifies strategies to cut electricity consumption by 25GW by 2030, equal to 35% of the peak electricity consumption in that year. The adoption of efficient technologies would reduce electricity use in lamps, air conditioners, refrigerators and other appliances.

With these technologies, Indonesia can avoid building 50 of the planned power plants by 2030.

Efficient technologies to reduce load

Our model forecasts energy demand by appliance types and analyses different scenarios of technology adoption to understand their impacts on future electricity loads.

We found the efficient technologies provide the same service to the households (lighting, cooling, etc) but use less energy. This makes them as much as 50% less expensive for consumers to run.


For example, common technologies are LEDs (light-emitting diodes), which produce more light with less heat loss, inverter ACs, which allow the AC to work at variable speed, and increased refrigerator insulation, which will keep food compartments cold longer.

While some Indonesians have already chosen to buy efficient technologies, tens of millions of energy-consuming products are entering households for the first time in the coming years.

Therefore, it is important to have strong policies in place to eliminate inefficient products and promote efficient ones in the market.

In particular, with sales of air conditioners growing at 7.5% every year in Indonesia, we find over half of the potential savings could come from this product alone.

Further research by our team has shown efficient cooling technologies using an inverter drive are available in Indonesia at a cost not necessarily higher than the inefficient ones.

In terms of climate impacts, we found efficient appliances and lighting could achieve nearly 27% of the energy sector emission-reduction target. That's 84.5 million tons of CO₂ saved by 2030. This makes it an essential tool in reducing carbon emissions (decarbonisation) of Indonesia's energy sector, along with deployment of renewable energy.

The ministry has introduced the national sectoral targets for energy conservation into the National Elecricity Master Plan, or RUKN, to reduce energy consumption for the first time in 2019.

The plan stipulates that 37GW of the projected 166GW peak demand in 2030 can be avoided through energy conservation for the next ten years.

Energy conservation relies on energy-efficient technologies (this is what our research focuses on) as well as changes in consumer behaviours (such as turning off the light when you leave a room).

Recommendations

As electricity demand grows in Indonesia at the same time as the country pursues clean energy, energy efficiency is a critical tool for financial viability and energy security.

Energy efficiency means using less energy to perform the same task. Technologies now offer us the benefits of energy efficiency. Energy-efficiency policies support the deployment of these technologies.

We recommend that Indonesia consider energy efficiency as a resource for meeting the country's future energy needs.

Even with low coal prices, energy efficiency is the cheapest way to provide electricity to the Indonesian people.

Typically, we have found the cost of saving a unit of electricity (kWh) is around 2-3 cents, compared to the typical household electricity rate of 10-11 cents/kWh in Indonesia.

Energy efficiency will also help with the integration of renewable energy (like solar PV) by reducing the evening peak demand and the need for energy storage systems or expensive plants that are run only for high demand, such as gas-fired "peaker" plants.

Because of the shape of the load—high peak demand at 8pm—the system will need additional capacity that baseload cannot meet, i.e. coal.

We recommend the Ministry of Energy and Mineral Resources turn to the 37GW energy conservation target to help the country meet its climate commitments of 29% unconditional emission reduction by 2030.

We hope our research can help prioritise policy action and track progress towards the country's clean energy and climate goals.

Implementing these targets will help save the government money, reduce local and global pollution, and ultimately will reduce costs for Indonesian consumers.

Ultraviolet light can be used against coronavirus — just not in the way Trump imagines

Jon Ward Senior Political Correspondent, Yahoo News•April 25, 2020


WASHINGTON — President Trump’s mention Thursday of treating COVID-19 with ultraviolet light was part of a rambling digression that included speculation about administering disinfectants to patients, prompting confusion and alarm from medical experts.

The president’s invocation of pseudoscience — which he claimed on Friday had been a joke intended “sarcastically” to provoke reporters — overshadowed the news from the briefing about evidence, first reported last week by Yahoo News, that ultraviolet light does destroy the coronavirus. Researchers have shown it can be used to disinfect surfaces and kill viruses in ambient air in ways that could be used to reduce transmission in public spaces.

“Continuous very low dose-rate far-UVC light in indoor public locations is a promising, safe and inexpensive tool to reduce the spread of airborne-mediated microbial diseases,” wrote a team of researchers in a 2018 paper published in Scientific Reports.

Transmission of the coronavirus is thought to be more common through particles spread through the air than by contact with hard surfaces, but scientists are still working to understand how the virus spreads.

Yet if commercially available UV products were to mitigate some of the risk of contracting the coronavirus, that might help ease the transition out of a total lockdown. “This approach may help limit seasonal influenza epidemics, transmission of tuberculosis, as well as major pandemics,” the scientific researchers wrote in 2018.

The key is advances in UV lighting technology, specifically the advent of “far-UVC” lamps, which operate at a wavelength of 222 nanometers, a frequency that doesn’t penetrate skin or the outer layer of the human eye. Previously, disinfecting ultraviolet could not be used in public spaces because the wavelengths used, of 254 nanometers and up, can cause skin cancer and damage the eyes.

By contrast, the 2018 paper found that “far-UVC light cannot penetrate even the outer (non living) layers of human skin or eye” but that “because bacteria and viruses are of micrometer or smaller dimensions, far-UVC can penetrate and inactivate them.”

David Brenner, director of Columbia University’s Center for Radiological Research, said earlier this week that far-UVC light “can be safely used in occupied public spaces, and it kills pathogens in the air before we can breathe them in.”

“Most approaches focus on fighting the virus once it has gotten into the body. Far-UVC is one of the very few approaches that has the potential to prevent the spread of viruses before they enter the body,” Brenner said.

A group of researchers at the Center for Radiological Research published a study in 2017 that “tested the hypothesis that there exists a narrow wavelength window in the far-UVC region, from around 200-222 nm, which is significantly harmful to bacteria, but without damaging cells in tissues.”

The study found that far-UVC light kills pathogens “without the skin damaging effects associated with conventional germicidal UV exposure.”

Two other studies have examined the impact of far-UV light on skin using mice and found that “222 nm-UVC lamps can be safely used for sterilizing human skin.”

One company, Healthe, is already selling a few different UV light products, including far-UV lights meant to be used in public spaces. One is a downlight that can be installed in the ceiling of an average room. There is also a portal, similar to a metal detector, that claims it “inactivates over 90% of contaminants” if a person stands — arms up — inside the portal for 10 to 12 seconds.

The company says another way to use ultraviolet is to irradiate air as it passes through a sealed unit, like a building air-conditioning system. Since that doesn’t expose people to the rays, it can use different, more powerful wavelengths.

Despite these advances, public attention was distracted on Friday by the continued controversy over the president’s remarks the previous day.

“I was asking a question sarcastically to reporters like you, just to see what would happen,” Trump said in the Oval Office. “I was asking a sarcastic question to the reporters in the room about disinfectant on the inside.”

He claimed he had not asked his medical experts in the White House briefing room on Thursday to look into injecting disinfectants into the human body. “I thought it was clear,” he said.

But the president’s comments on Thursday were anything but clear. His remarks were so jumbled it was hard to know what exactly he meant at times.

Trump spoke on Thursday just after the head of the Science and Technology Directorate at the Department of Homeland Security, Bill Bryan, had spoken to reporters about the impact of sunlight on coronavirus particles in outdoor public spaces, and had also mentioned testing bleach as a disinfectant.

“So, supposing we hit the body with a tremendous — whether it’s ultraviolet or just very powerful light — and I think you said that that hasn’t been checked, but you’re going to test it. And then I said, supposing you brought the light inside the body, which you can do either through the skin or in some other way, and I think you said you’re going to test that too. It sounds interesting.

“And then I see the disinfectant, where it knocks it out in a minute. One minute. And is there a way we can do something like that, by injection inside or almost a cleaning. Because you see it gets in the lungs and it does a tremendous number on the lungs,” Trump said. “So it would be interesting to check that. So, that, you’re going to have to use medical doctors with. But it sounds — it sounds interesting to me. So we’ll see. But the whole concept of the light, the way it kills it in one minute, that’s — that’s pretty powerful.”

Later in the briefing, Trump asked Dr. Deborah Birx, a medical expert on his coronavirus task force, about the possibility of using heat or light to treat a COVID-19 infection — rather than kill the coronavirus in the environment.

“Not as a treatment,” she replied.

The new coronavirus is quickly destroyed by sunlight, according to new research announced by a senior US official on Thursday, though the study has not yet been made public and awaits external evaluation.

William Bryan, science and technology advisor to the Department of Homeland Security secretary, told reporters at the White House that government scientists had found ultraviolet rays had a potent impact on the pathogen, offering hope that its spread may ease over the summer.

"Our most striking observation to date is the powerful effect that solar light appears to have on killing the virus, both surfaces and in the air," he said.

"We've seen a similar effect with both temperature and humidity as well, where increasing the temperature and humidity or both is generally less favorable to the virus."

But the paper itself has not yet been released for review, making it difficult for independent experts to comment on how robust its methodology was.

It has long been known that ultraviolet light has a sterilizing effect, because the radiation damages the virus's genetic material and their ability to replicate.

A key question, however, will be what the intensity and wavelength of the UV light used in the experiment was and whether this accurately mimics natural light conditions in summer.

"It would be good to know how the test was done, and how the results were measured," Benjamin Neuman, chair of biological sciences at Texas A&M University-Texarkana, told AFP.

"Not that it would be done badly, just that there are several different ways to count viruses, depending on what aspect you are interested in studying."

Virus inactivated

Bryan shared a slide summarizing major findings of the experiment that was carried out at the National Biodefense Analysis and Countermeasures Center in Maryland.

It showed that the virus's half-life—the time taken for it to reduce to half its amount—was 18 hours when the temperature was 70 to 75 degrees Fahrenheit (21 to 24 degrees Celsius) with 20 percent humidity on a non-porous surface.

This includes things like door handles and stainless steel.

But the half-life dropped to six hours when humidity rose to 80 percent—and to just two minutes when sunlight was added to the equation.

When the virus was aerosolized—meaning suspended in the air—the half-life was one hour when the temperature was 70 to 75 degrees with 20 percent humidity.

In the presence of sunlight, this dropped to just one and a half minutes.

Bryan concluded that summer-like conditions "will create an environment (where) transmission can be decreased."

He added, though, that reduced spread did not mean the pathogen would be eliminated entirely and social distancing guidelines cannot be fully lifted.

"It would be irresponsible for us to say that we feel that the summer is just going to totally kill the virus and then if it's a free-for-all and that people ignore those guides," he said.

Previous work has also agreed that the virus fares better in cold and dry weather than it does in hot and humid conditions, and the lower rate of spread in southern hemisphere countries where it is early fall and still warm bear this out.

Australia, for example, has had just under 7,000 confirmed cases and 77 deaths—well below many northern hemisphere nations.

The reasons are thought to include that respiratory droplets remain airborne for longer in colder weather, and that viruses degrade more quickly on hotter surfaces, because a protective layer of fat that envelops them dries out faster.

US health authorities believe that even if COVID-19 cases slow over summer, the rate of infection is likely to increase again in fall and winter, in line with other seasonal viruses like the flu.

Perfect storm: Lombardy's virus disaster is lesson for world

As Italy prepares to emerge from the West's first and most extensive coronavirus lockdown, it is increasingly clear that something went terribly wrong in Lombardy, the hardest-hit region in Europe's hardest-hit country.

Italy had the bad luck of being the first Western nation to be slammed by the outbreak, and its official total of 26,000 fatalities lags behind only the U.S. in the global death toll. Italy's first homegrown case was recorded Feb. 21, at a time when the World Health Organization was still insisting the virus was "containable" and not nearly as infectious as the flu.

But there is also evidence that demographics and health care deficiencies collided with political and business interests to expose Lombardy's 10 million people to COVID-19 in ways unseen anywhere else, particularly the most vulnerable in nursing homes.

Virologists and epidemiologists say what went wrong there will be studied for years, given how the outbreak overwhelmed a medical system long considered one of Europe's best, while in neighboring Veneto, the impact was significantly more controlled.

Prosecutors, meanwhile, are deciding whether to lay any criminal blame for the hundreds of dead in nursing homes, many of whom don't even figure into Lombardy's official death toll of 13,269, half of Italy's total.

By contrast, Lombardy's front-line doctors and nurses are being hailed as heroes for risking their lives to treat the sick under extraordinary levels of stress, exhaustion, isolation and fear. One WHO official said it was a "miracle" they saved as many as they did.

Here's a look at the perfect storm of what went wrong in Lombardy, based on interviews and briefings with doctors, union representatives, mayors and virologists, as well as reports from Italy's Superior Institute of Health, national statistics agency ISTAT and the Organization for Economic Cooperation and Development, which advises developed economies on policy.

Unions and mayors of some of Lombardy's hardest hit cities say the country's main industrial lobby group, Confindustria, exerted enormous pressure on authorities to resist lockdowns and production shutdowns on the grounds that the economic cost would be too great in a region responsible for 21% of Italy's GDP.

CAUGHT UNPREPARED

Italy was the first European country to halt all air traffic with China on Jan. 31, and even put scanners in airports to check arrivals for fever. But by Jan. 31, it was already too late. Epidemiologists now say the virus had been circulating widely in Lombardy since early January, if not before.

Doctors treating pneumonia in January and February didn't know it was the coronavirus, since the symptoms were so similar and the virus was still believed to be largely confined to China. Even after Italy registered its Feb. 21 case, doctors didn't understand the unusual way COVID-19 could present itself, with some patients experiencing a rapid decline in their ability to breathe.


"After a phase of stabilization, many deteriorated quickly. This was clinical information we didn't have," said Dr. Maurizio Marvisi, a pneumologist at a private clinic in hard-hit Cremona. "There was practically nothing in the medical literature."

Because Lombardy's intensive care units were already filling up within days of Italy's first cases, many primary care physicians tried to treat and monitor patients at home. Some put them on supplemental oxygen, commonly used for home cases in Italy.

That strategy proved deadly, and many died at home or soon after hospitalization, having waited too long to call an ambulance.

Reliance on home care "will probably be the determining factor of why we have such a high mortality rate in Italy," Marivi said.

Italy was forced to use home care in part because of its low ICU capacity: After years of budget cuts, Italy entered the crisis with 8.6 ICU beds per 100,000 people, well below the OECD average of 15.9 and a fraction of Germany's 33.9, the group said.

As a result, primary care physicians became the front-line filter of virus patients, an army of mostly self-employed practitioners who work within the public health system but outside Italy's regional hospital network.

Since only those with strong symptoms were being tested because Lombardy's labs couldn't process more, these family doctors didn't know if they themselves were infected, much less their patients.

With so little clinical information available, doctors also had no guidelines on when to admit patients or refer them to specialists. And being outside the hospital system, they didn't have the same access to protective masks and equipment.

"The region was extremely behind in giving us protective equipment and it was inadequate, because the first time, they gave us 10 surgical masks and gloves," said Dr. Laura Turetta in the city of Varese. "Obviously for our close contact with patients, it wasn't the correct way to protect ourselves."

The Lombardy doctors' association issued a blistering letter April 7 to regional authorities listing seven "errors" in their handling of the crisis, key among them the lack of testing for medical personnel, the lack of protective equipment and the lack of data about the contagion.

The regional government and civil protection agency defended their efforts, but acknowledged that Italy was dependent on imports and donations of protective equipment and simply didn't have enough to go around.

LOST WEEKS


Two days after registering Italy's first case in the Lombardy province of Lodi, sparking a quarantine in 10 towns, another positive case was registered more than an hour's drive away in Alzano in Bergamo province. Whereas the emergency room of the Lodi-area hospital was closed, the Alzano ER reopened after a few hours of cleaning, becoming a main source of contagion.

Internal documents cited by Italian newspapers indicate the handful of serious pneumonia cases the Alzano hospital saw as early as Feb. 12 were likely COVID-19. At the time, Italy's health ministry recommended tests only for people who had been to China or been in contact with a suspected or confirmed positive case.

By March 2, the Superior Institute of Health recommended Alzano and nearby Nembro be sealed off as the towns in Lodi had been. But political authorities never implemented the quarantine recommendation there, allowing the infection to spread for a second week until all the Lombardy region was locked down March 7.

"The army was there, prepared to do a total closure, and if it had been done immediately maybe they could have stopped the contagion in the rest of Lombardy," said Dr. Guido Marinoni, head of the association of doctors in Bergamo province. "This wasn't done, and they took softer measures in all of Lombardy, and this allowed for the spread."

Asked why he didn't seal off Bergamo sooner, Premier Giuseppe Conte argued the regional government could have done so on its own. Lombardy's governor, Attilio Fontana, shot back that any mistake "was made by both. I don't think that there was blame in this situation.''

Lombardy has one-sixth of Italy's 60 million people and is the most densely populated region, home to the business capital in Milan and the country's industrial heartland. Lombardy also has more people over 65 than any other Italian region, as well as 20% of Italy's nursing homes, a demographic time bomb for COVID-19 infections.

"Clearly, with the benefit of hindsight, we should have done a total shutdown in Lombardy, everyone at home and no one moves," said Andrea Crisanti, a microbiologist and virologist advising the Veneto regional government. But he acknowledged how hard that was, given Lombardy's outsize role in the Italian economy, which even before the pandemic was heading toward a recession.

"Probably for political reasons, it wasn't done," he told reporters.

INDUSTRIAL LOBBYING


Unions and mayors of some of Lombardy's hardest hit cities now say the country's main industrial lobby group, Confindustria, exerted enormous pressure to resist lockdowns and production shutdowns because the economic cost would be too great in a region responsible for 21% of Italy's GDP.

On Feb. 28, a week into the outbreak and well after more than 100 cases were registered in Bergamo, the province's branch of Confindustria launched an English-language social media campaign, #Bergamoisrunning, to reassure clients. It insisted the outbreak was no worse than elsewhere, that the "misleading sensation" of its high number of infections was due to aggressive testing, and that production in steel mills and other industries was unaffected.

Confindustria launched its own campaign in the larger Lombardy region, echoing that message, #Yeswework. Milan's mayor proclaimed that "Milan doesn't stop."

In the end, the Milan field hospital was barely used, treating only a few dozen patients. (AP Photo/Luca Bruno)

At the time, Confindustria Lombardy chief Marco Bonometti acknowledged the "drastic measures" needed in Lodi but sought to lower the sense of alarm.

"We have to let people know they can go back to life as it was, while safeguarding their health," he said.

Even after the Rome-based national government locked down all of Lombardy March 7, it allowed factories to stay open, sparking strikes from workers worried their health was being sacrificed to keep Italy's industrial engine rolling.

"It was a huge error. They should have taken the example where the first cluster was found," said Giambattista Morali of the metalworkers' union in the Bergamo town of Dalmine. "Keeping factories open didn't help the situation; obviously it worsened it."

Eventually, all but essential production was shut down nationwide March 26. Confindustria's national president, Carlo Bonomi, has been urging that industry be reopened, but in a safe way.

"The paradigm has changed," Bonomi told RAI state television. "We can't make Italians secure if we don't reopen factories. But how do we make factories safe to secure Italians?"

It's a tough sell, given Lombardy is still adding an average of 950 infections daily, while other regions add from a few dozen to 500 apiece, with most new cases registered in nursing homes. Italy is set to begin a gradual reopening May 4, leading with regions farther south where the outbreak is more under control.

Lombardy probably will be last to fully open, with its 72,000 confirmed cases, 70% of Italy's total, and estimates that the real number could be 10 times that.

A COSTLY FIELD HOSPITAL


Perhaps no initiative better illustrates Italy's confused coronavirus response than the 200-bed field hospital built in less than two weeks on the grounds of Milan's convention center.

The hospital was unveiled to great fanfare on March 31, the fruit of a 21 million euro ($23 million) fundraising campaign headed by Lombardy's governor, a member of the right-wing League party, to try to ease pressure on regional ICUs, which on that date were near capacity at 1,324 patients.

The national civil protection agency opposed the plan, arguing it could never equip it with ventilators or personnel in time. Instead, the agency, which reports to the rival 5-Star-Democratic government in Rome, preferred smaller field units set up outside hospitals and a program to move critical patients elsewhere.

In the end, the Milan field hospital was barely used, treating only a few dozen patients. Since it opened, Lombardy has seen pressure on its ICUs fall considerably, with just over 700 people needing intensive care today.

Fontana, the governor, defended the decision and said he would do it again, telling Radio 24: "We had to ... prepare a dam in case the epidemic overcame the embankment."

NURSING HOME 'MASSACRE'


While the regional government was focused on building the field hospital and scrambling to find ICU beds, its testing capacity lagged and Lombardy's nursing homes were in many ways left to fend for themselves.

Hundreds of elderly have died in Lombardy and across Italy in what one WHO official has termed a "massacre" of those most vulnerable to the virus. Prosecutors are investigating dozens of nursing homes, as well as measures taken by local health authorities and the regional governments that may have worsened the problem.

Lombardy has more nursing homes than any other region, housing at least 24,000 elderly, and it registered more dead at those facilities than others too. Of the 3,045 dead from Feb. 1 to April 15 in the region, 1,625 were either positive for the virus or showed its symptoms, according to preliminary results from a survey by the Superior Institute of Health.

Of particular attention to prosecutors was the March 8 decision by the regional government to allow recovering COVID-19 patients to be put in nursing homes to free up hospital beds. The region says it required the homes guarantee the patients would be isolated, but it's not clear who was responsible to ensure that or whether anyone checked.

Even before that, staff at some homes said management prevented them from wearing masks for fear of scaring residents.

A March 30 regional decree, again aimed at easing pressure on Lombardy's ICUs, told nursing home directors to not hospitalize sick residents over 75 if they had other health problems. The decree said it was "opportune to treat them in the same facility to avoid further risks of decline in transport or during the wait in the emergency room."

For the elderly at a nursing home in Nembro, one of the hardest-hit towns in Bergamo province, the decree amounted to a death warrant. But it wasn't the first or only one that gave the home's managers the sense that they were being abandoned.

When management proactively barred visitors on Feb. 24 to try to protect residents and staff from infection, local health authorities responded by threatening sanctions and a loss of accreditation for cutting off family visits, said the facility's new director, Valerio Poloni.

In the end, 37 of the 87 residents died in February and March. Its doctor, as well as Poloni's predecessor as director, also tested positive, were hospitalized and died. A nursing home resident couldn't get admitted to the hospital in late February because the ER was too crowded.

The facility's health director, Barbara Codalli, said she was told to use her existing resources to treat the sick. "The patient returned a few hours later, and a few days later the patient died," she told La7 television.

To date, none of the surviving residents has been tested. Poloni said tests were expected to begin in a few days. Two more residents died so far in April, but the situation seems under control.

''We are tranquil,'' he said.

Italy's far-right League hurt by response to coronavirus in heartland

Sara Rossi, Emilio Parodi  APRIL 25, 2020

MILAN (Reuters) - The coronavirus crisis has left Italy’s northern economic powerhouse a disaster zone and raised awkward questions for far-right opposition leader Matteo Salvini’s League party, which has dominated the region’s politics for years.

Ever since its creation as a separatist movement in the 1980s, the League’s heartland has been in the prosperous small towns of Lombardy around the financial capital Milan, the area that has now borne the brunt of the COVID-19 crisis.

Under Salvini’s leadership, the League has become Italy’s strongest party, mixing nativist and anti-immigration policies with harsh criticism of the European Union that has at times included threats to quit the euro.

But the crisis in his home region has dented Salvini’s once all-conquering image, making it harder to land attacks on Prime Minister Giuseppe Conte’s coalition government in Rome, which Salvini quit spectacularly last year in a failed attempt to force a new election.

Two months after the first outbreak of COVID-19 in a small town outside Milan, Lombardy remains one of the world’s worst-hit regions, accounting for half of Italy’s 26,000 dead.

As local families have seen elderly relatives dying alone in overflowing hospitals or nursing homes, the League-led regional government, which runs the health system, has faced increasing criticism from its own supporters.

“For us seeing the hospitals full and the ambulances that didn’t arrive was unthinkable,” said Ivan Dallagrassa, who runs a building company in Gorno near Bergamo and lost an uncle and probably an aunt to COVID-19. “At the last elections I voted for the League because I liked Salvini but I wouldn’t do it again.”

The troubles in Lombardy have started to undermine national support for the party, which had already been losing ground to parties like the right-wing Brothers of Italy group, while Conte has enjoyed sky-high approval ratings of over 60 percent.

A poll on Sunday by the Ipsos institute for the Corriere della Sera newspaper put the League on 25.4 percent, down from 31.1 a month ago, accelerating a steady slide since it took 34.3 to become the largest party in European elections a year ago.

HALF OF ITALY’S DEAD


The regional government has been criticised for communication missteps, policy zig-zags, lack of early testing and failing to procure enough protective equipment. Magistrates have begun investigating a wave of deaths in the region’s nursing homes.

Salvini’s own position, like those of many politicians on all sides, has shifted during the crisis. Early on he blamed foreigners, demanding to close Italy’s borders; he was then a sceptic of shutting down business, before ultimately joining calls for a strict lockdown.


Whatever stance he has taken on the national level, his fortunes are tied to the performance of his party in administering the region it dominates.

Local officials point to actions they have taken, including setting up a huge emergency hospital, bringing in millions of protective masks and setting aside billions of euros to boost the economy.

“There’s no justification for these attacks,” regional governor Attilio Fontana, a close Salvini ally, told local TV station ETV last week, saying much of the criticism was motivated by “political speculation”.

But while criticism from opponents may be predictable, many normally sympathetic voices have also expressed deep misgivings.

“The main criticism I would make of the management of this crisis by the region of Lombardy is organisational failure,” said Roberto Francese, who heads a centre-right administration as mayor of Robbio, 50 kilometres southwest of Milan.

Lombardy officials have also had to defend pre-crisis health reforms, which favoured big hospitals and private sector providers and stripped down local services now seen as vital to treating patients before they end up in intensive care.

“Local medical services have gone backwards, it’s true,” said Lorenzo Demartini, a hospital radiologist and a former League mayor of Mede, near Milan. “They have been dismantled, I can confirm it.”

By contrast, the League governor in neighbouring Veneto, Luca Zaia, has emerged strengthened from the crisis, widely praised for decisive action backed by a strong local health system that kept hospital admissions down.

While the League has weathered previous storms, Lorenzo Pregliasco, head of political analysis firm Youtrend, said the “mishandling of a huge crisis affecting ordinary people” was a very different problem from the financial scandals that regularly blight Italian politics.

“The party’s appeal is based on Salvini’s charismatic leadership but also on a reputation for pragmatic and effective government at local level,” he said. “That has been damaged.”
