EVALUATION OF METHOD

APPLICABILITY: The working range for B[a]P is 3 to 150 µg/m 3 for a 400-L air sample. Specific sample sets may require modification in filter extraction solvent, choice of measurement method, and measurement conditions.

INTERFERENCES: Any compound which elutes at the same GC retention time may interfere. Heat, ozone, NO 2, or UV light may cause sample degradation.

OTHER METHODS: This revises P&CAM 183 [2]. The spectrophotometric methods, P&CAM 184 and 186 [2], have not been revised. Method 5506 (HPLC) uses the same sampling technique and is more sensitive.
