IAQ and public housing EJ study

Hi, is anyone monitoring indoor air quality? I’m involved in the early stages of an IAQ pilot study to test whether residents in public housing in the District of Columbia are at risk due to lower IAQ. This is a grant funded community data science project to impact EJ communities.

We are interested in about 50 sensors to measure PM (and also considering CO2 as an indicator of poor ventilation). We can compare IAQ in public housing versus IAQ in private residents in the more affluent wards.

I was a bit alarmed to learn there is no consensus on IAQ standards for minimal human exposure like we have with the NAAQS.
