Three locations in Bangkok were sampled with the use of a high volume sampler. None of the 30 samples contained HCB while average concentrations of BaP were found. The data i ndi cated seasonal variat ions i n BaP concentrations. Vehicle emissions were identified as the most like ly source of BaP emissions.
