Summary

The objective of this project is to characterize 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). This project deals solely with the analysis of chemical constituents and targets a wide variety of organic species, ions and metals. The goal is to differentiate sources of coarse particles and fine particles, and identify candidate marker species that are unique to the coarse fraction of ambient particulate matter.
