Description:
A study was conducted to determine whether the High Volume Small Surface Sampler (HVS3) can quantitatively collect polycyclic aromatic hydrocarbons (PAH) will polychlorinated biphenyls (PCB) adsorbed onto house dust 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. ess 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. herefore, the HVS3 without a PUF filter was shown to quantitatively collect PAH and PCB in house dust, and it was used to collect house dust from the remaining seven houses. he collected house dust, foundation soil, and entryway soil samples were analyzed for PAH, PCB, and lead (Pb) by gas chromatography/mass spectrometry (GC/MS) and XRF analysis. he concentration of PAH was higher in the house dust than in the foundation soil. he PAH concentrations of the entryway soil were higher than that in the foundation soil samples in all houses. he concentration of the sum of all the target PAH in the house dust ranged from 6.1 to 26 ug/g (ppm) and that in the foundation soil ranged from 1.1 to 3.7 ppm. he concentration of the sum of PAH in the entryway soil samples varied from 2.9 to 20 ppm. he concentration sum of all the target PCB in the house dust and soil varied from 260 ng/g to 760 ng/g (ppb) and 58 to 240 ppb, respectively. he concentration of lead in the house dust ranged from 250 to 2250 ppm and 200 to 4000 ppm, respectively. or all but three houses, higher concentrations of lead were found in the foundation soil than in the house dust. y contrast, concentrations of PAH and PCB were higher in the house dust than in the soil samples.
