Pilot Study on Coarse PM Monitoring.

摘要

The primary objectives of the coarse PM pilot speciation study were to: (1) develop the target species analyte list for routine speciation monitoring (what species need to be measured); (2) evaluate and define appropriate analysis methods for routine speciation monitoring and the necessary SOPs; (3) evaluate the field performance of the dichot samplers for routine speciation monitoring (e.g., comparing gravimetric mass and speciation to the FRM by difference data and assessing dichot collocated precision); (4) learn about sampling and operational issues regarding the use of dichots; and (5) evaluate data from the study to inform several issues related to coarse PM speciation measurements.
