This method is for the determination of polynuclear aromatic hydrocarbons. The sample is collected on PTFE filters followed by XAD-2 sorbent tubes, extracted with 5 mL organic solvent appropriate to the sample matrix, and then analyzed by capillary column GC with flame ionization detection. The working range for B[a]P is 3 to 150 µg/m³ for a 400-L air sample. Specific sample sets may require modification in filter extraction solvent, choice of measurement method, and measurement conditions. Note: This revises P&CAM 183.

* The analytes and detection limits listed for each method represent the typical detection limits and analytes reported for that particular method. Keep in mind that analyte lists may vary from laboratory to laboratory. Detection limits may also vary from lab to lab and are dependent upon the sample size, matrix, and any interferences that may be present in the sample.
