Our #OpenAccess @natcomms paper on metals in air and racial segregation: rdcu.be/cYKf9 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.

Summer 2020 and 2023 each had more unhealthy PM2.5 days of exposure than all previous years COMBINED this century.
In this ES&T Letters, @Smogdr documents the summertime trends in #ParticulateMatter exposure arising from #wildfire smoke across the continental U.S. #AirPollution @CSUMechEngr @ColoradoStateU #OpenAccess: go.acs.org/baj

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.

Most evaluations of low-cost #aerosol sensors have focused on their measurement bias compared to regulatory monitors. Few evaluations have applied fundamental principles of aerosol science to increase our understanding of how such sensors work and could be improved... READ MORE🔎

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. stocks.apple.com/AKFmRuyA7Tr…

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 tandfonline.com/doi/full/10.…

Buildings breathe. If it's smoky outside, you should be taking precautions to protect your health indoors as well as out. I walked through every possible home configuration I could think of with @Smogdr (window a/c? central a/c?) to find out what to do. heatmap.news/wildfire-smoke-…

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

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: fire.airnow.gov

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. ehp.niehs.nih.gov/doi/10.128…

Seeing "The Mask Mandates Did Nothing" trending is an illustration of how opinion editors at mainstream outlets spread disinformation about science and cause mass harm.
Bret Stephens once called global warming "mass hysteria" and claimed climate science had been "discredited." Please don't believe a single word he writes about COVID-19.
