Met up with a fellow birder this morning, talked about birds and, of course, wildfire smoke this week.

They said they've been trying to find air purifiers at local stores, but found every one was sold out.

I said they could make their own, for less than $100 US dollars.

Shared photo of purifier I built as well as Corsi-Rosenthal box link.

'Dangerous' air quality in Detroit, Minneapolis as thick wildfire smoke shrouds the sky for millions

Smoke from wildfires burning in Ontario have caused air quality to reach "dangerous" levels across Canada, and the northeastern and midwestern United States. And it could get worse before conditions improve.

" Massive plumes of smoke are descending across parts of Canada and the United States, creating dangerous air quality and scenes reminiscent of the historic wildfire smoke outbreak from three summers ago.

" 'In 2023, a major fire outbreak in Quebec caused days of unhealthy air quality in the northeastern U.S.,' AccuWeather Vice President of Forecast Operations Dan DePodwin said. 'This event could cause similar levels of poor air quality in spots.'

"Air quality alerts have been issued for millions of people, including across all of #Connecticut, #Delaware, #Massachusetts, #Michigan, #NewHampshire, #NewJersey, #NewYork, #Ohio, #Pennsylvania, #RhodeIsland and #Wisconsin.

"Over 800 wildfires are currently burning across Canada, including dozens that are out of control across western #Ontario, the source of most of the smoke. 'Many of these fires may have been started by lightning,' AccuWeather Senior Meteorologist Brett Anderson said.

"On Wednesday, #Toronto had some of the worst air quality in North America, reaching 'very unhealthy' levels with an AQI of 220. #BostonMA was not far behind with an unhealthy AQI of 147.

" 'When the AQI climbs into the 150+ range for a full day outside, that’s in the ballpark of [smoking] 7 to 9 cigarettes,' Dr. Jonathan M. Tan, division chief of General Anesthesiology at Children’s Hospital of Philadelphia, told AccuWeather.

"Conditions deteriorated by Thursday morning, with widespread "dangerous" air quality across nearly all the Great Lakes region and into parts of the Northeast. Minneapolis and Duluth, Minnesota, as well as Detroit, were among the worst cities at daybreak Thursday, with AQIs over 340.

" 'Any exposure to the air, even for a few minutes, can lead to serious health effects on everybody,' Plume Labs said.
Avoid outdoor activities.' "

How to Build a #CorsiRosenthalBox

Apr 15, 2022

"Richard L. Corsi, dean of the UC Davis College of Engineering, explains how to build a #CorsiRosenthal box. Dr. Corsi is an internationally recognized expert in the field of indoor air quality, with a specific interest in physical and chemical interactions between pollutants and indoor materials. His concept for a low-cost, accessible, and effective air cleaner, the Corsi-Rosenthal box, is now being used as an open-source do-it-yourself approach worldwide for reducing exposure to the #SARSCoV-2 virus, #WildfireSmoke and more."

Easing back into #DoomAndGloom... The #AQI is awful here in #Maine /#NorthernNewEngland today... And it's predicted to be worse tomorrow! I did find that wearing a PM 2.5 filter mask is helping when I'm outside. When I forgot to wear a mask, I couldn't stay outside very long!

The smoke from #Canada’s #wildfires may be even more #toxic than usual

A legacy of #mining means that #ToxicMetals could be carried along plumes of smoke.

by Matt Simon, June 5, 2025

"More than 200 wildfires are blazing across central and western Canada, half of which are out of control because they’re so hard for crews to access, forcing 27,000 people to evacuate. Even those nowhere near the wildfires are suffering as smoke swirls around Canada and wafts south, creating hazardous air quality all over the midwestern and eastern parts of the United States. The smoke is even reaching Europe.

"As the climate changes, the far north is drying and warming, which means wildfires are getting bigger and more intense. The area burned in Canada is now the second largest on record for this time of year, trailing behind the brutal wildfire season of 2023. That year, the amount of #carbon blazed into the atmosphere was about three times the country’s #FossilFuel emissions. And the more carbon that’s emitted from wildfires — in Canada and elsewhere — the faster the #PlanetaryWarming, and the worse the fires.

" 'There’s obviously the #ClimateFeedback concern,' said Mike Waddington, an environmental scientist at McMaster University in Ontario who studies Canada’s forests. 'But increasingly we’re also concerned about the smoke.'

"That’s because there’s much more to wildfire smoke than charred sticks and leaves, especially where these blazes are burning in Canada. The country’s #forests have long been #mined, operations that loaded #soils and #waterways with #ToxicMetals like #lead and #mercury, especially before clean-air standards kicked in 50 years ago. Now everyone downwind of these wildfires may have to contend with that legacy and those pollutants, in addition to all the other nasties inherent in #WildfireSmoke, which are known to exacerbate respiratory and cardiac problems.

" 'You have there the burning of these organic soils resulting in a lot of carbon and a lot of #ParticulateMatter,' said Waddington. 'Now you have this triple whammy, where you have the metals #remobilized in addition to that.'

"What exactly is lurking in the smoke from Canadian wildfires will require further testing by scientists. But an area of particular concern is around the mining city of #FlinFlon, in #ManitobaCanada, which is known to have elevated levels of toxic metals in the landscape, said Colin McCarter, an environmental scientist who studies pollutants at Ontario’s #NipissingUniversity. Flin Flon’s 5,000 residents have been evacuated as a wildfire approaches, though so far no structures have been destroyed.

"But a fire doesn’t need to directly burn mining operations to mobilize toxicants. For example, in #Yellowknife, in Canada’s #NorthwestTerritories, #GoldMining operations between 1934 and 2004 spread #arsenic as far as 18 miles away, adding to a landscape with an already high concentration of naturally occurring arsenic. In a paper published last year, Waddington and McCarter estimated that between 1972 and 2023, wildfires around Yellowknife fired up to 840,000 pounds of arsenic into the atmosphere. Arsenic is a known carcinogen associated with cardiovascular disease, diabetes, and developmental problems, according to the World Health Organization. (After the 2023 #LahainaFire in Maui, officials reported elevated levels of arsenic, lead, and other toxic substances in ash samples. California officials also found lots of lead in smoke from 2018’s #CampFire.)"
