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.

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
