Pinal County Study

This project was aimed at  characterizing the chemical composition of coarse and fine particulate matter (PM) to support source attribution and to quantify local sources and regional transport contributing to elevated PM levels in Pinal County (AZ). The study was based on over a year of sampling and analyzing samples from 3 sites.
