  1. The scale, which runs from 0 to 500, was designed by the #EPA & measures the density of five different #pollutants in the #air: ground-level #ozone, #particulates, #CarbonMonoxide, #NitrogenDioxide & #SulfurDioxide.

    Several spots in northeastern Minnesota, closest to the fires recorded had AQI readings well into the “hazardous” range on Wednesday.

Real men don’t worry about #blacklung & #airborne #particulates, let alone #climatechange." The energy worldview of Donald #Trump & #MAGA, @GeraldKutney.

  14. “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.

  20. [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

  22. @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.

  24. 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.

  26. A quartet of mushroom-shaped structures tower nearly 6 meters above the Olympic Village. Known as Aerophiltres, these devices filter particulates out of the air to provide cleaner air for the Village, despite its proximity to major roadways. There’s no need to change out the filters in the Aerophiltres, though, because they don’t have any. Instead, the devices ionize fine particles, encourage them to clump together, and then capture them on highly-charged metal plates. A fan near the base sucks polluted air in through the top and expels clean air at the ground level. According to the engineers, the system is capable of removing 95% of particulates and producing nine Olympic-sized swimming pools’ worth of clean air each hour. Compared to traditional systems — which require lots of power to suck air through filters that get progressively more clogged — the Aerophiltres are energy efficient, highly effective, and easy to maintain.
