•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.
