The White House Coronavirus Task Force warned governors in private reports this week that “the COVID risk to all Americans is at a historic high” and said virus-mitigation efforts in many states are still not strong enough.”We are in a very dangerous place due to the current, extremely high COVID baseline and limited hospital capacity,” the new reports, dated Nov. 29, read. “A further post-Thanksgiving surge will compromise COVID patient care, as well as medical care overall.”This article was originally published by the Center for Public Integrity, a nonprofit investigative news organization based in Washington, D.C. Read on, and to ensure your health and the health of others, don’t miss these Sure Signs You’ve Already Had Coronavirus.The task force also issued some of its strongest warnings yet to individual Americans, even though the reports to governors are not made public. It said anyone over age 65 should not enter indoor public spaces with unmasked people and should have groceries and medications delivered. It also said that people under 40 who gathered with others outside their households for Thanksgiving should assume they became infected, isolate themselves and be tested immediately. “You are dangerous to others,” the task force said.Forty-seven states and the District of Columbia were in the red zone for new cases in this week’s report — one fewer than the week prior — meaning they had more than 100 new cases per 100,000 residents. But 39 states were in the White House’s red zone for deaths — three more than the prior week — meaning they had more than two new deaths per 100,000 residents. North and South Dakota again led the nation in both cases and deaths per capita.”In many areas of the USA, state mitigation efforts remain inadequate, resulting in sustained transmission,” the task force said. “All states and counties must flatten the curve now.”The White House has said it does not share the reports publicly because it wants states to lead the pandemic response. The Center for Public Integrity is collecting and publishing the documents. Last week it exclusively obtained the 50-state version of the Nov. 22 reports, revealing that the White House was taking tough stances with many states that refuse to share their reports, including Indiana and South Dakota.”Improved public observance of social distancing measures is urgently needed to limit overrunning of hospital capacity,” the White House told officials in Indiana. “The Governor’s active engagement and support of mitigation measures are critical.”The White House reports this week again urged states to do more rapid testing. The task force also urged seniors to get tested immediately if they gathered with others for Thanksgiving and start experiencing symptoms: “If you are over 65 or have significant medical conditions and you gathered outside of your immediate household, you are at a significant risk for serious COVID infection; if you develop any symptoms, you must be tested immediately as the majority of therapeutics work best early in infection,” the reports read.RELATED: COVID Symptoms Usually Appear in This Order, Study FindsThe states in the red zone for cases in this week’s report (meaning they had more than 100 new cases per 100,000 residents in the week prior):North DakotaSouth DakotaWyomingNew MexicoMinnesotaIowaNebraskaIndianaKansasMontanaUtahWisconsinAlaskaColoradoRhode IslandIllinoisOhioNevadaOklahomaMichiganIdahoMissouriKentuckyArkansasPennsylvaniaArizonaTennesseeWest VirginiaDelawareNew JerseyConnecticutLouisianaMississippiMassachusettsMarylandFloridaWashingtonTexasCaliforniaNorth CarolinaNew YorkAlabamaOregonVirginiaSouth CarolinaNew HampshireDistrict of ColumbiaGeorgiaThe states in the red zone for test positivity in this week’s report (meaning more than 10 percent of tests in the state were positive in the week prior):IdahoMontanaKansasOklahomaMissouriUtahIowaNebraskaNevadaIndianaNew MexicoSouth DakotaOhioWyomingMichiganKentuckyTennesseeNorth DakotaAlabamaMississippiIllinoisMinnesotaWisconsinPennsylvaniaArizonaColoradoTexasThe states in the red zone for deaths (meaning they had more than more than two new deaths per 100,000 residents in the week prior): South DakotaNorth DakotaNew MexicoMontanaWyomingIowaMichiganMinnesotaIndianaIllinoisWisconsinNebraskaRhode IslandTennesseeMissouriMississippiPennsylvaniaKansasColoradoWest VirginiaArkansasConnecticutIdahoNevadaLouisianaOhioTexasMarylandNew JerseyOklahomaAlabamaAlaskaKentuckyMassachusettsUtahFloridaSouth CarolinaArizonaNorth CarolinaAnd to ensure your health and the health of others, don’t miss these 35 Places You’re Most Likely to Catch COVID.About the Author: Liz Essley Whyte is a reporter for the Center for Public Integrity.
Microplastics could be eliminated from wastewater at source – E&T Magazine
A team of researchers from the Institut national de la recherche scientifique (INRS), Quebec, Canada, have developed an electrolytic process for treating wastewater, degrading microplastics at the source.
Microplastics are fragments of plastic less than 5mm long, often contained in toiletries or shedding from polyester clothing. They are present in virtually every corner of the Earth, and pose a particularly serious threat to marine ecosystems. High concentrations of microplastics can be carried into the environment in wastewater.
There are no established degradation methods to handle microplastics during wastewater treatment; although some techniques exist, these involve physical separation as a means of filtering the pollutant. These techniques do not degrade microplastics, which requires additional work to manage the separated fragments. So far, research into degradation of microplastics has been very limited.
The INRS researchers, led by water treatment expert Professor Patrick Drogui, decided to try degrading plastic particles through electrolytic oxidation – a process that does not require the addition of chemicals.
“Using electrodes, we generate hydroxyl radicals to attack microplastics,” Drogui said. “This process is environmentally friendly because it breaks them down into CO2 and water molecules, which are non-toxic to the ecosystem.”
Drogui and his colleagues experimented with different anode materials and other parameters such as current intensity, anode surface, electrolyte type, electrolyte concentration and reaction time. They found that the electrolytic oxidation could degrade more than 58 ± 21 per cent of microplastics in one hour. The microplastics appeared to degrade directly into gas rather than breaking into smaller particles.
Lab-based tests on water artificially contaminated with fragments of polystyrene showed a degradation efficiency as high as 89 per cent.
“This work demonstrated that [electrolytic oxidation] is a promising process for degradation of microplastics in water without production of any waste or by-products,” the researchers wrote in their Environmental Pollution report.
Drogui envisions this technology being used to treat microplastic-rich wastewater emerging from sources such as commercial laundries.
“When this commercial laundry water arrives at the wastewater treatment plant, it is mixed with large quantities of water, the pollutants are diluted and therefore more difficult to degrade,” he explained. “Conversely, by acting at the source, i.e. at the laundry, the concentration of microplastics is higher, thus more accessible for electrolytic degradation.”
Next, the researchers will move on to experimenting with degrading microplastics on water outside the artificial laboratory environment. Real commercial laundry water contains other materials that can affect the degradation process, such as carbonates and phosphates, which can trap radicals and limit degradation. If the technology is effective under these circumstances, the researchers plan to conduct a study to determine the cost of scaling up this treatment to implement in laundries.
Last week, researchers from the University of Barcelona published a study suggesting that encouraging a greater proliferation of seagrass meadows in the shallows of oceans could help trap, extract and carry marine plastic debris to shore.

Eliminating microplastics in wastewater directly at the source – EurekAlert
A research team from the Institut national de la recherche scientifique (INRS) has developed a process for the electrolytic treatment of wastewater that degrades microplastics at the source. The results of this research have been published in the Environmental Pollution journal.
Wastewater can carry high concentrations of microplastics into the environment. These small particles of less than 5 mm can come from our clothes, usually as microfibers. Professor Patrick Drogui, who led the study, points out there are currently no established degradation methods to handle this contaminant during wastewater treatment. Some techniques already exist, but they often involve physical separation as a means of filtering pollutants. These technologies do not degrade them, which requires additional work to manage the separated particles.
Therefore, the research team decided to degrade the particles by electrolytic oxidation, a process not requiring the addition of chemicals. “Using electrodes, we generate hydroxyl radicals (* OH) to attack microplastics. This process is environmentally friendly because it breaks them down into CO2 and water molecules, which are non-toxic to the ecosystem,” explains the researcher. The electrodes used in this process are more expensive than iron or steel electrodes, which degrade over time, but can be reused for several years.
An effective treatment
Professor Drogui envisions the use of this technology at the exit of commercial laundries, a potential source of microplastics release into the environment. “When this commercial laundry water arrives at the wastewater treatment plant, it is mixed with large quantities of water, the pollutants are diluted and therefore more difficult to degrade. Conversely, by acting at the source, i.e., at the laundry, the concentration of microplastics is higher (per litre of water), thus more accessible for electrolytic degradation,” explains the specialist in electrotechnology and water treatment.
Laboratory tests conducted on water artificially contaminated with polystyrene showed a degradation efficiency of 89%. The team plans to move on to experiments on real water. “Real water contains other materials that can affect the degradation process, such as carbonates and phosphates, which can trap radicals and reduce the performance of the oxidation process,” says Professor Drogui, scientific director of the Laboratory of Environmental Electrotechnologies and Oxidative Processes (LEEPO).
If the technology demonstrates its effectiveness on real commercial laundry water, the research group intends to conduct a study to determine the cost of treatment and the adaptation of the technology to treat larger quantities of wastewater. Within a few years, the technology could be implemented in laundry facilities.

The waiting is over in the wild rose province. Curling Alberta has made its decision on what teams will represent the province at this year’s Scotties and Brier in the Calgary bubble. Laura Walker, last year’s provincial champion, has accepted the invitation to play at this year’s Scotties. “We were excited to get the call. We wanted to wear the blue and gold and we take so much pride in representing our province,” Walker told CBC Sports. “We know there are many deserving teams in Alberta and we don’t take this honour lightly.” Walker made her Scotties debut in Moose Jaw, Sask., last year and finished with a 3-4 record. On the men’s side, Brendan Bottcher will once again be going to the Brier. Bottcher is last year’s provincial champion. He has played in the last three Brier championship games, losing twice to Brad Gushue, and two years ago to fellow Albertan Kevin Koe. It’s Bottcher’s fifth appearance at the Brier. The decision was made Sunday afternoon by the Curling Alberta board members. Massive repercussions This was a much anticipated decision as it will have massive repercussions on what other teams will attend the national championships. Curling Canada has announced a one-time expanded field for the Scotties and Brier, citing these extraordinary times in the midst of a pandemic as the reason for increasing the field to 18 teams. Normally, there are 16 teams competing at the event. However, Curling Canada has said there will be no wild-card game as it’s unfair to have teams travel all that way and make plans to only play one game. The governing body for the sport wants the best teams in the country at the event. So the first two spots will be determined by the CRTS rankings — the two teams that would normally compete in the wild-card game. The third and final team will be determined through a number of criteria. Kevin Koe, who brought in John Morris to join the team in place of Colton Flasch during the off-season, is ranked sixth. He’ll be at the event. “While we don’t agree with the decision made we are excited to have the opportunity to compete in the Calgary bubble,” Koe told CBC Sports. “Regardless of the uniform we are wearing we are a very motivated team and excited to compete for another Canadian championship and represent all our sponsors and fans.” Mike McEwen’s Manitoba rink is ranked fifth and is also a lock for the event. The last spot would then most likely go to Glenn Howard out of Ontario, as his team is currently ranked ninth. WATCH | Heroux, Jones break down Calgary culring bubble: Women’s side more complicated The women’s side is a tad more complicated. With Walker being named as Alberta representative, that means Tracy Fleury’s Manitoba rink is locked in for one of the spots with her No. 2 ranking. The next team without a Scotties spot is Chelea Carey. Her team disbanded during the off-season — Carey is a free agent. Then it’s Kelsey Rocque’s Alberta rink at No. 5. The issue for Rocque is that she changed two of four players during the off-season — and Curling Canada rules explicitly state three of four members need to return to be eligible. That eliminates the Rocque rink from the two CRTS spots — however, the team might be considered for the third spot. There is a potential situation brewing that could include last year’s world junior champion Mackenzie Zacharias. Her Manitoba rink is ranked 11th. This all comes in the wake of a number of jurisdictions cancelling their playdowns. To date, eight jurisdictions across Canada have now cancelled their playdowns — they include: B.C., Alberta, Saskatchewan, Manitoba, Ontario, Northern Ontario, Quebec and Nova Scotia. The final spots are expected to be filled over the next couple of weeks. Women Canada — Kerri Einarson. B.C. — Corryn Brown. Alberta — Laura Walker Saskatchewan — Sherry Anderson. Manitoba — Jennifer Jones. Ontario — Rachel Homan. Northern Ontario — Krysta Burns. Quebec — Laurie St-Georges. Nova Scotia — Jill Brothers. Nunavut — Lori Eddy. Men Canada — Brad Gushue. B.C. — Steve Laycock. Alberta — Brendan Bottcher Saskatchewan — Matt Dunstone. Manitoba — Jason Gunnlaugson. Ontario — John Epping. Northern Ontario — Brad Jacobs. Quebec — Michael Fournier. Yukon — Dustin Mikkelsen. Nunavut — Peter Mackey. There are six major curling events planned for the Calgary curling bubble starting with the Scotties on Feb. 19. That will then lead into the men’s national championship beginning of March. 5. Following these two events, the mixed doubles championship will take place all leading to the men’s world curling championship, set to begin in early April. The final two events held inside the bubble include two Grand Slam of Curling bonspiels.
