  6. theguardian.com/environment/20. "At the time [1991], it was believed a #temperature increase could lead to longer, lusher #grasses. But instead of flourishing, the grasses & #wildflowers started to disappear, replaced by #sagebrush. The experimental #meadows morphed into a desert-like #scrubland. Even the #fungi in the #soils were transformed by #heat."

  7. Though there are many #heavymetals that #coalmining can release to our #freshwater, #selenium has been noted as a particularly risky #pollutant as it bioaccumulates in the #environment reaching toxic levels for #fish, #animals living in riparian areas, and potentially in agricultural #soils and #plants grown in them. This is a risk not only to human #health and the health of aquatic #ecosystems, but also risks the reputation of our regional agricultural products.

  11. I use eggshells as a soil enhancer. I also sterilize the shells (300 F for 30 minutes) before grinding them into a fine powder (using a mortar and pestle).

    Using #Eggshells as #Lime in #Soils

    Cracking the Code: Can Ground Eggshells be Used as a Liming Source?

    April 2, 2025 by Leon Martinez

    Excerpt: "Factors Affecting Eggshell Liming Efficacy

    The efficacy of eggshell liming depends on several factors, including:

    - Particle size: Finely ground eggshells are more effective at raising soil pH than coarsely ground eggshells.
    - Application rate: The amount of eggshells applied to the soil can impact their effectiveness as a liming source.
    - Soil type: Eggshell liming may be more effective in certain soil types, such as acidic soils with low calcium content.

    Practical Applications of Eggshell Liming

    If you’re interested in trying eggshell liming, here are some practical tips to get you started:

    - Collect and dry eggshells: Collect eggshells from your kitchen or local farms and dry them thoroughly to prevent mold and bacterial growth.
    - Grind eggshells: Grind the dried eggshells into a fine powder using a coffee grinder or mortar and pestle.
    - Apply eggshells to soil: Mix the ground eggshells into the soil at a rate of 1-2 cups per 10 square feet.

    Conclusion

    While ground eggshells show promise as a liming source, their effectiveness depends on several factors, including particle size, application rate, and soil type. As with any liming material, it’s essential to monitor soil pH and adjust application rates accordingly. With proper use and application, ground eggshells can be a cost-effective, eco-friendly alternative to traditional liming materials."

  16. 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.)"
