- W2338863973 abstract "The analytical method to determine polycyclic aromatic hydrocarbons (PAH) in house dust and soil samples was validated. The method consists of sonication with 10 mL of hexane (C6) for two 30-minute extractions, and analysis of the C6 extract by gas chromatography/mass spectrometry (GC/MS). An eight-home pilot field study was conducted in Columbus, Ohio before and after the 1992/1993 heating season to obtain concentration profiles of PAH in house dust and track-in soil, and to determine whether track-in of outdoor soil residues is an important source of PAH in house dust. A total of 19 PAH, ranging from 2-ring naphthalene to 7-ring coronene, was monitored. The sum of the concentrations of all target PAH in the house dust samples evaluated in this study raged from 41 to 580 ppm and from 25 to 310 ppm in the samples collected during october 1992 and April 1993. Higher concentrations were observed in entryway soil samples and the sums of the concentrations of target PAH ranged from 68 to 4,000 ppm and 58 to 5,500 ppm in samples collected before (October 1992) and after (April 1993) the winter heating season, respectively. The sum of the concentrations of PAH in the pathway soil samples variedmore » from 3.0 to 1,200 ppm in samples collected before the heating season. The sum of the concentrations of PAH ranged from 0.58 to 610 ppm and from 0.63 to 63 ppm in pathway soil and foundation soil samples collected after the heating season, respectively.« less" @default.
