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.)"

Advocates demand halt to #uranium #mine near the #GrandCanyon

#EnergyFuels says #nuclear power is necessary to fight #ClimateChange, but #Indigenous tribes fear losing their homes

By Matthew Rozsa

"The Grand Canyon truly lives up to its name, being the largest canyon on Earth and one of the most popular national parks in America. But due to #UraniumMining in the area, some advocates are warning it could become the site of a future #EnvironmentalDisaster, which threatens to make one Indigenous village 'extinct.'

"More than 80 groups signed onto a statement on Monday — representing Indigenous communities, scientists and environmental nonprofits such as the #SierraClub and the #CenterForBiologicalDiversity — directed at President #JoeBiden and #Arizona Gov. #KatieHobbs, demanding they close the #PinyonPlain uranium mine, which is located near the Grand Canyon.

"'We have a choice in front of us. Allowing the Pinyon Plain mine to proceed is subjecting this landscape and its interconnected waters to a legacy of devastation and disregarding the rights of the #IndigenousPeoples on the land,' Sanober Mirza, Arizona program manager for the National Parks Conservation Association, said in the statement. 'Or we can choose a different path — one that holds a promise of protecting the Grand Canyon’s cultural sanctity, its people and natural resources.'

"To understand why the mine's opponents feel so strongly, one can turn to #AmberReimondo, who work as energy director at a conservationist non-profit called the #GrandCanyonTrust. Reimondo explained to Salon by email that, on the one hand, #Biden permanently banned mining operations on nearly 1 million acres of federal managed lands by creating the #BaajNwaavjo I'tah Kukveni - Ancestral Footprints of the Grand Canyon National Monument in August 2023. Yet the Pinyon Plain mine was #exempt from this prohibition, and Reimondo argues that the impact on the region has been 'several fold.'

"'What they've created here is a long-term, slow motion #EnvironmentalDisaster."

"'The Grand Canyon region as a whole and especially the location of the mine, is deeply significant to Indigenous cultures and is a place where tribal members have conducted #ceremonies, collected medicine, hunted, and more, for centuries,' Reimondo said. 'The mine also overlies critical and complex [and] not well understood groundwater systems. One #aquifer in particular — the #RedWallMuavAquifer — is the sole source of water for the remote #HavasupaiVillage of #Supai inside the Grand Canyon. The mine poses a #contamination threat to these #groundwater resources not just today, but importantly, after the mine's mere 28-month operational lifespan has concluded and the mining operator 'cleans up' and moves on.'

"Supai is so remote, it's only accessible only by helicopter or an 8-mile mule ride or hike, Reimondo explained, noting that if the newly-oxygenated groundwater comes into contact with nearby rocks, minerals like #arsenic and #uranium will be dissolved by the groundwater and enter aquifers used by the local community and essential to local ecology, including #HavasuFalls. Taylor McKinnon, Southwest Director for the Center for Biological Diversity, expressed similar concerns.

"'Ultimately, this mine is going to require political leadership,' McKinnon told Salon in an interview, referring to both the Biden and #Hobbs administrations. 'Those administration's agencies have the authority to fix this problem if they so choose, and that's what they should do.'

"We have detailed strenuously for years that neither regulators nor industry can ensure against the permanent and irretrievable damage to Grand Canyon's aquifers and springs," McKinnon added. "This mine was approved originally in 1986, under a record of decision from the US Forest Service under a presumption that it was highly unlikely that the mine would encounter groundwater, and further unlikely that if it did, it had the potential to contaminate deeper aquifers in the springs that they feed. Subsequent state permitting from the #ArizonaDepartment OfEnvironmentalQuality has basically parroted those same assumptions.'

"Yet McKinnon alleges that in 2016 the mine punctured a perched aquifer, causing roughly 10 million gallons of water per year to drain into the mine workings. From there he asserts that a surface pond formed with water that has concentrations of uranium and arsenic far in excess of the Environmental Protection Agency (#EPA)'s water quality standards. Not only does this threaten the local endangered and endemic species, but it also impacts the nearby Havasupai tribe.

"Havasupai means 'people of the blue-green water,' McKinnon said. "It's their longstanding cultural identity, and it is the water they drink, they farm with and that provides for all of their tourism economy because it is this just a beautiful series of massive verdant waterfalls that flow through the village and down into a series of waterfalls and pools where people camp and they derive tourism dollars.'

"In a 2022 letter of opposition, the Havasupai Tribal Council, laid out what is at stake in the uranium mining controversy.

"'Our identity as a people is intrinsically intertwined with the health of #HavasuCreek and the environment to which it gives life,' the tribe’s letter explained. 'We use this water for drinking, #gardening and irrigating, municipal uses, and #cultural and #religious uses. If the water source becomes contaminated like we have seen in other areas of Arizona due to uranium mining, we will no longer be able to live in our homes and Supai Village will become extinct.'

"These fears are based on precedent. The nearby #NavajoNation is scattered with old uranium mines — over 500, in fact — awaiting cleanup, exposing locals to risk of '#LungCancer from inhalation of #radioactive particles, as well as #BoneCancer and impaired kidney function from exposure to #radionuclides in drinking water,' according to the EPA. Likewise, members of the #UteMountain #Ute tribe in #WhiteMesa, Utah have protested against uranium mines they say have contaminated local groundwater, air and even wildlife."
