Air Toxics Sampling and Analysis (2 of 2)
•EPA-approved methods for collection and analysis of suspended particulate matter are documented in the “Compendium of Methods for the Determination of Inorganic Compounds in Ambient Air.”
–Chapter IO-3, Chemical Species Analysis of Filter-Collected Suspended Particulate Matter (SPM), is of considerable importance to the air toxics ambient monitoring program.
–Several different methods for speciated particulate analyses are available.
–Each have advantages and disadvantages depending on the target analytes and desired minimum detection limits.
–For Hazardous Air Pollutant (HAP) metals, IO-3.5 (Inductively Coupled Plasma / Mass Spectrometry (ICP/MS)) offers the lowest detection limits.
Detailed information about these monitoring methods is available at: https://www.epa.gov/ttn/amtic/airtox.html.
