Canada #WildfireSmoke to be a periodic problem into August across #Midwest, #Northeast
Prevailing winds will direct more wildfire smoke from western #Ontario into the Midwest and Northeast often well into August. Needed rain to put out the fires may be scarce.
By Alex Sosnowski, Jul 20, 2026
Excerpt: " Hundreds of large wildfires are burning across Canada and the United States.
"There are 809 active #wildfires in #Canada, according to the Canadian Wildland Fire Information System. To date this year, there have been 3,575 fires that have burned 2.7 million hectares.
"Even more fires have burned across the #US. 'So far this year, 40,771 fires have burned more than 3.9 million acres across the United States,' according to the (U.S.) National Interagency Fire Center newsroom. 'Fires in the Northwest and the fires in northern Minnesota pose the greatest demand for firefighting resources. Resource assignments are being prioritized based on life and property risk, operational impact, and probability of success.' "

An Easy-to-Build #CorsiRosenthalBox Using Modular #PCFan Systems
Jim Rosenthal
October 21, 2023"The first Corsi-Rosenthal Box was built in August of 2020. It was presented as an #OpenSource' concept so that as many people as possible could have low-cost cleaner, safer indoor air. It is based on sound engineering principles, but it is really very simple. Use 4 (or 5) MERV 13 filters in a 'box' configuration with a box fan. The best thing is – it works! Consequently, many thousands have been made all over the world.
It has also been very enjoyable to see the continuous stream of ingenuity, creativity, and knowledge that has been expended to create a 'better' Corsi-Rosenthal Box. Much of this was out of necessity since many countries in the world do not have the same filters and fans as we have in North America. Many really smart and creative people have developed designs of the CR Box concept that work with the fans and filters available in their countries.
We have also had many people in North America who have contributed to the development of a “better mousetrap” of a DIY air cleaner. For effectiveness and low cost, it is very hard to beat the original box fan and “box” of filters design. But there have been many interesting modifications that have been shown to provide some real benefits. The most interesting of these is the use of PC fans to replace the box fan. The PC fans have the advantages of low noise and low energy usage but are not as economical or as easy to construct.
Here is another alternative – modular PC fan systems. A company by the name of AC Infinity (www.acinfinity.com) makes them. Their primary uses are for audio-visual cabinets and indoor horticulture. However, they provide low noise, high air flow and low power usage. In other words, they should work for Corsi-Rosenthal boxes. My initial tests confirm this conclusion. "
Note: I am not finding the fans on the AC Infinity website. I have found computer fans that can do the job on eBay and Amazon.

Just finished adding a page for Canada: https://wildfiresmokeresources.neocities.org/Canada
Currently only have resources for Montréal and London, as well as one (excellent) national resource. (Thank you to whoever submitted the FireSmoke.ca link today!) I'll be focused on getting all the info I currently have for the US added to the site over the next couple days, but after that will spend more time seeking out Canadian mask blocs and other resources.
If you have a resource you'd like to share for Canada (or anywhere else in North America), you can send it to me here on Mastodon via replies or DM, or submit it via this Cryptpad form: https://cryptpad.fr/form/#/3/form/view/03ab8efd32850a3d5d5c376d39ed0284/

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.

Do-It-Yourself #AirCleaners: Making Cleaner Air More Accessible
Published September 6, 2023
"Everyone should have the right to breathe clean air. However, during wildfires, the cost and availability of clean air technologies and reliable power sources can create challenges for people trying to protect their health from wildfire smoke. Recognizing these barriers, EPA and other health, environmental, and nonprofit organizations have provided instructions and materials for creating do-it-yourself (#DIY) air cleaners. DIY air cleaners are a more affordable and accessible alternative to commercial versions and can be constructed using a box fan and a high-efficiency home air filter. Securing the filter to the fan creates an effective, simple air cleaning system.
"This DIY solution filters out smoke particles and improves indoor air quality, but its use has raised key questions about the devices’ safety and effectiveness. EPA scientists and their colleagues are conducting research to answer these questions.
" 'This research was highly anticipated, particularly by EPA’s western regions, who have suffered from terrible wildfire smoke for years without the ability to recommend more affordable air filtering options to the public,' noted Meredith Bauer, Assistant Director of EPA Region 9’s Air and Radiation Division. 'It is important that we develop tools that allow everyone to protect themselves and their families when wildfire smoke is in the air.' "

#AirQuality plummets in #Boston, #Toronto as thick wildfire smoke shrouds the sky for millions
Smoke from wildfires burning in Ontario have caused air quality to reach unhealthy levels across #Canada, and the northeastern and midwestern United States. And it could get worse before conditions improve.
By Brian Lada, Jul 15, 2026
Excerpt: "Toronto had some of the worst air quality in North America on Wednesday morning, reaching 'very unhealthy' levels with an AQI of 220. 'Health effects will be immediately felt by sensitive groups and should avoid outdoor activity,' Plume Labs said. 'Healthy individuals are likely to experience difficulty breathing and throat irritation.'
"In Boston, air quality reached 'unhealthy' conditions on Wednesday morning with an AQI of 147. Little improvement is expected in the city into Thursday. "

We’re getting smoky skies and diminished air quality in Southern Oregon’s Rogue Valley - from fires just across the border in N. Calif’s Siskiyou County. I count 12 fires, the largest ones are 0% contained. We’re waiting desperately for the first rains of Fall, which are predicted next week. We’ll see how that goes. #SouthernOregon #Oregon #RogueValley #wildfires #WildfireSmoke #GlobalWarming #ClimateChange

Not just human health! The #Toxic Blend of LA’s Urban #WildfireSmoke Will Have Lasting Health Consequences
Los Angeles residents are breathing bits of "cars, metal pipes, plastics."
By Zoya Teirstein, January 22, 2025“These fires are different from previous quote-unquote ‘wildfires,’ because there are so many structures that burned,” said Yifang Zhu, a professor of environmental health sciences at the University of California, Los Angeles. 'Everything in the households got burned — cars, metal pipes, plastics.'
"#Wildfiresmoke is toxic. Burning trees and shrubs produce very fine #particulatematter, known by the shorthand PM 2.5, which burrow deep into the lungs and can even infiltrate the bloodstream, causing cold- and flu-like symptoms in the short term, and heart disease, lung cancer, and other chronic issues over time.
"But the fires that raced through Los Angeles burned thousands of homes, schools, historic buildings, and even medical clinics, blanketing the city in thick smoke. For several days after the first fire started, the city’s air quality index, or #AQI, exceeded 100, the threshold, typically seen during wildfires, at which air becomes unhealthy to breathe for children, the elderly, and those with asthma. In some parts of the city, the AQI reached 500, a number rarely seen and always hazardous for everyone.
"At the moment, air pollution experts know how much smoke fills the air. That’s shown improvement in recent days. But they don’t know what’s in it. 'What are the chemical mixtures in this smoke?' asked Kai Chen, an environmental scientist at the Yale School of Public Health. 'In addition to fine particulate matter, there are potentially other hazardous and #carcinogenic organic compounds — gas pollutants, trace metals, and microplastics.'
"Previous research shows that the spikes in unhealthy air quality seen during such events lead to higher rates of hospitalizations for issues like asthma, and even contribute to heart attacks among those with that chronic disease. A 2024 study on the long-term effects of smoke exposure in California showed that particulate matter from wildfires in the state from 2008 to 2018 contributed to anywhere from 52,000 to 56,000 premature deaths. A health assessment of 148 firefighters who worked the Tubbs Fire, which burned more than 36,000 acres in Northern California in 2017 and destroyed an unusually high number of structures, found elevated levels of the #PFAS known as forever chemicals, #HeavyMetals, and flame retardants in their blood and urine.
"The L.A. County Department of Public Health has formally urged people to stay inside and wear masks to protect themselves from windblown toxic dust and ash. Air quality measurements don’t take these particles into account, which means the air quality index doesn’t reveal the extent of contaminants in the air.
"Zhu and her colleagues have been collecting samples of wildfire smoke in neighborhoods near the fires. It’ll be months before that data is fully analyzed, but Zhu suspects she will find a dangerous mix of chemicals, including, potentially, #asbestos and lead — materials used in many buildings constructed before the 1970s.
"The risk will linger even after the smoke clears. The plumes that wafted over the landscape will deposit chemicals into drinking #water supplies and #contaminate# soil. When rains do come, they’ll wash #ToxicAsh into streams and across the land, said Fernando Rosario-Ortiz, an environmental engineer and interim dean of the University of Colorado Boulder environmental engineering program. 'There’s a lot of manmade materials that are now being combusted. The potential is there for contamination,' he said, noting that little research on how toxic ash and other byproducts of wildfires in urban areas currently exists. 'What we don’t have a lot of information on is what happens now.'
"After the Camp Fire razed Paradise, California, in 2018, water utilities found high levels of volatile organic compounds [#VOCs] in #DrinkingWater. Similar issues have arisen in places like Boulder County, Colorado, where the Marshall Fire destroyed nearly 1,000 structures in 2021, Rosario-Ortiz said, though the presence of a contaminant in a home doesn’t necessarily mean it will be present in high levels in the water. Still, several municipal water agencies in Los Angeles issued preemptive advisories urging residents not to drink tap water in neighborhoods near the Palisades and Eaton fires. It’ll be weeks before they know exactly what’s in the water.
"As wildfires grow ever more intense and encroach upon urban areas, cities and counties must be prepared to monitor the health impacts and respond to them. 'This is the first time I’ve ever even witnessed or heard anything like this,' said Zhu, who raised her daughter in Los Angeles and has lived there for decades, said. 'Even being in the field studying wildfires and air quality impacts, I never imagined that a whole neighborhood, a whole community in Palisades, would burn down.'"
