Particulate Matter as PM 10 in the Atmosphere.” Monitoring for TSP is addressed in 40 CFR 50,
Appendix B, “Reference Method for Determination of Suspended Particulate Matter in the
Atmosphere (High-Volume Method).” Lead is analyzed from the TSP filters in accordance with
40 CFR 50, Appendix G, “Reference Method for the Determination of Lead in Suspended
