Air samples collected at 23 sites in Kanagawa Prefecture, Japan in 1998 and 1999 were analyzed for PCBs by a high-resolution gas chromatograph/mass spectrometer. Concentrations of PCBs ranged from 10 to 3290 pg/m3N (geometric average, 120 pg/m3N) and were mostly less than 140 pg/m3N. The toxicity equivalency quantity (TEQ) values of co-planar PCBs ranges from not detected (ND) to 0.35 pg-TEQ/m3 N (mean value, 0.00063 pg-TEQ/m3 N). Cl3-PCBs comprised the highest level in many air samples. PCB… CONTINUE READING
