Yes and no. Fine PM (PM2.5) can fuck you up. Coarse PM (PM10) will make out with you and give you crabs. I have to test our rotor plants twice a year for the fine particulates but do not need to measure the coarse. It was proven a few years ago that although the coarse are bad it was the fines that were causing most of the issues previously attributed to them. I do however test for the coarse anyway because when the next study says they are worse I will be prepared!
