Evaluation of HVS3 Sampler for Sampling Polycyclic Aromatic Hydrocarbons andPolychlorinated Biphenyls

摘要

The objectives of this study were to (1) determine whether the High Volume SmallSurface Sampler (HVS3) can quantitatively collect polycyclic aromatic hydrocarbons (PAH) and polychlorinated biphenyls (PCB) adsorbed onto house dust, and (2) obtain concentration profiles for PAH and PCB in house dust and foundation soil samples from nine houses in Seattle, Washington. In two of the houses, a polyurethane foam (PUF) filter was positioned after the cyclone in the HVS3 to determine the penetration of the cyclone by PAH and PCB adsorbed on the dust. Less than 3 percent of the PAH and less than 5 percent of the PCB were found on the PUF filter compared with the cyclone catch. Therefore, the HVS3 without a PUF filter can quantitatively collect PAH and PCB in house dust, and it was used to collect house dust from the remaining seven houses.
