#toxiclegacy — Public Fediverse posts

In #Yellowknife #NWT #Canada, people, animals, land and water have to live with the toxic Giant Mine and perpetually care for 230,000 tonnes of toxic arsenic trioxide. This project asks for people to join us in witnessing this monster's life.

Abstract:
"Climate change interacts with the sources and cycling of contaminants, such as radionuclides, in the environment. In this review, we discuss the implications of climate change impacts on existing and potential future sources of radionuclides associated with human activities to the marine environment. The overall effect on operational releases of radionuclides from the nuclear and non-nuclear sectors will likely be increased interference or prevention of normal operations due to weather-related events. For certain #RadioactiveWaste dumped at sea and sunken #NuclearSubmarines, the impact of climate change and ocean #acidification on the release of radionuclides and their subsequent fate in the marine environment should be considered further. Fluxes from secondary sources of radionuclides in the marine and terrestrial environment and cryosphere will change in response to climate change impacts such as sea level rise, warming and changes in precipitation patterns. In addition, climate change impacts may increase the risk of releases of radionuclides from operational and legacy wastes on land to the marine environment. Overall, our synthesis highlights that there is a need to understand and assess climate change impacts on sources of radionuclides to the marine environment to meet environmental and management challenges under future climate scenarios."

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.)"

The Dirty Deadly Front End of Nuclear Power — 15,000 Abandoned Uranium Mines (Pt. 1)

by Josh Cunnings, March 11, 2016

"The perplexing problem of these open, deadly, toxic messes was discussed between Emerson Urry and Arnie Gundersen.

"Urry: I want to go back for a minute to the uranium. We were talking about Fukushima and obviously the myriad isotopes that are put off as a byproduct of the nuclear fission that is happening in the reactor. It all starts there with the uranium, and there was quite a rush for that, and now we have all of these situations. To our understanding there are about 15,000 abandoned uranium mines that have been left in complete ruin with very little cleanup or remediation at all, just in the western United States. This has happened, by-and-large, because of an antiquated mining bill – the 1872 Mining Bill – still affecting these situations today – that kind of allowed miners to just walk away from these situations — but yet, they remain in the open leaching off tailings – blowing around #radioactive dust. I think there’s about 4,500 of these exposed mining sites just in #Navajo country – another 2,500 or so in #Wyoming. How do we deal with that situation? What does the future hold in those regards, and quite frankly, are we all being poisoned by these mines?

"Gundersen: I’ll give you another example of the same thing, and I would say 'yes' to everything you said is the quick answer. There is a mill-tailings site in Moab, #Utah. The Nuclear Regulatory Commission [#NRC] told the owner of the site that they needed to set aside six million dollars to clean it up. Well, the actual #cleanup is a billion dollars. What did the owner do? They declared #bankruptcy and walked away.

"Urry: And it wasn’t bonded? No bond?

"Gundersen: Right. It wasn’t bonded. You know, if you bonded uranium mining, you wouldn’t have uranium mining."

@DavidM_yeg #Postmedia has transformed the #FourthEstate to the #FilthEstate. Thanks Harper. We kicked your sorry ass to the curb, but you managed to leave us your #ToxicLegacy.

@gemelliz Apparently #CdnMedia has now completely morphed into the #FilthEstate. What was once our #FourthEstate has become a #Postmedia cesspool thanks to Harper. We kicked his sorry ass to the curb but his #ToxicLegacy lives on. DeSantis insanity is now considered #CdnNews

@andersonbooz @dianemarieposts Why is any #CdnMedia reporting this? The disgraced exPM is desperate to be a BIG IMPoRTANT player on the world scene but he’ll always be the 2-bit hustler Cdns booted to the curb. His #ToxicLegacy lives on through #Postmedia aka the #FilthEstate
