  3. TechCrunch: How Al Gore used AI to track 660M polluters. “The nonprofit Climate Trace, which Gore co-founded, on Wednesday launched a tool that uses AI to track fine particulate pollution from more than 660 million sources worldwide.”

  4. “Dispersion”

    In “Dispersion,” particles spread under the influence of an unseen fluid. Like Roman de Giuli’s work, filmmaker Susi Sie creates macro images that look like ice floes, deserts, and river deltas viewed from above. This similarity of patterns at both large and small scales is a specialty of fluid physics. Just as artists use it to mimic larger flows, scientists use it to study planet-scale problems in the lab.

  8. [Not very] Clean Air Zone proposal accepted.

    Initial quick reaction: In another bad decision from the government, the GMCA (not very) Clean Air Zone proposal has been accepted.  This was what the previous government sat on for three years. #GreaterManchester will be the only major city in the country without a proper clean air zone, its citizens condemned to breathe the #particulates and #NOx spewed by private cars and commercial vehicles

  10. @kim_harding and electric cars are almost as bad -- because most of those #particulates are from tyres and brakes.

    If we want to reduce cancerous air pollution, we need to move to lighter vehicles -- like bicycles.

  11. Hazelwood coalmine fire exposed residents of the LaTrobe Valley to toxic smoke particulates and gases for 45 days in 2014.
    A health Study finds ‘statistically significant association’ between exposure to fine particles in coalmine fire smoke and aging of lungs, equal to 4.7 years.

Of 134 countries and regions surveyed in the report, only seven – Australia, Estonia, Finland, Grenada, Iceland, Mauritius and New Zealand – are meeting a #WorldHealthOrganization (#WHO) guideline limit for tiny airborne particles expelled by cars, trucks and industrial processes. theguardian.com/environment/20

    In [1], the authors report: "high #temperatures during California #wildfires catalyzed widespread transformation of chromium to its #carcinogenic form in soil and #ash, as #HexavalentChromium" Cr(VI) - even "in wind-dispersible #particulates"

    The geographic distribution of susceptible #soils, and of "fire incidents illustrate the broad global threat of wildfire #smoke- and dust-born metals to populations" [1]

    A study in 2019 [2] already suggested this pathway for Cr(VI) formation in soil.

  16. ‘Fraudulent, broken instrument’: Why our measurements don’t capture the true risks of wildfire smoke

    The Air Quality Health Index is a tool developed by the federal government with input from provinces and other stakeholders to inform Canadians on the risk of poor air quality in their area

  17. Revealed: almost everyone in Europe is breathing toxic air
    Guardian investigation finds 98% of Europeans breathing highly damaging polluted air linked to 400,000 deaths a year

  18. it's really cold in the PNW so indoor heated air is *REALLY* dry. I have a couple of those #ultrasonic #humidifier mist #diffuser thingies but stopped using them after I heard they put dangerous micro mineral particles in the air.

    Does anyone know if this #danger is real? I understand the EPA hasn't said they're unsafe, but, y'know.
