Our #OpenAccess @natcomms paper on metals in air and racial segregation: .Take home 1/5:.1. Racial/ethnic disparities in exposure to toxic metals (in air) is much worse than what has been reported for PM2.5 mass (up to 300% worse). That's really bad.

After decades of decline in US air pollution, 2023 became the worst Summer on record for PM2.5 this century. #wildfire is here and it’s here to stay.

Dr. Wall told me she created SOGES at CSU so that faculty had a refuge where scholarly conversation and collaboration could flourish, unhindered by academic barriers. She succeeded in that vision, in a space where many before her did not. Thank you, Diana.

Boom. This new annual PM2.5 limit (9 ug/m3) chosen by EPA represents great progress towards cleaner, healthier air for everyone. In Colorado, you can expect visibility to improve along the Front Range as a result.

The new regulations could save thousands of lives from deadly air pollution, according to the U.S. Environmental Protection Agency's calculations.

Teardown-> model of the #PMS5003 PM sensor shows.1. It’s a PM counter, not a nephelometer. 2. It can count 0.3-0.5 um particles and that’s about it. 3. It CANNOT report PM size distributions, PM coarse, PM10.@Jess_Tryner @ASTJournal @SureshDhaniyala

If you’re worried about #wildfire #smoke inhalation, go grab that #N95 mask you set aside on May 11. It will help…a lot.

Good morning #Colorado! Feeling run down? Itchy eyes? Sore throat? Headache? It’s probably not your allergies. We have a massive #wildfire #PM2.5 #smoke intrusion from Canada. Stay indoors and run those air cleaners! Real-time info here:

Imagine how your lungs would feel if your kitchen stove was an open fire burning indoors. Campfires are for camping, not everyday cooking. Thanks to Nate Seltenrich @EHPonline for spreading the word on this global health and climate issue.
