Description:
The analytical methods were developed for the determination of PAH and PCBs in the dust and soil based on sonication with hexane and 10% ether/hexane, respectively, and analysis by gas chromatography/mass spectrometry (GC/MS). uantitative recoveries of spiked perdeuterated PAH and 13C labeled PCB were obtained using the above methods. n an eight-home field evaluation, the concentrations of the sum of all target PAH in the house dust ranged from 16 to 550 ppm, from 41 to 580 ppm, and from 25 to 310 ppm in the samples collected during June 1992, October 1992, and April 1993, respectively. igher concentrations were observed in entryway soil samples and the concentrations of the sum of target PAH ranged from 68 to 4000 ppm and 58 to 5500 ppm in samples collected before (October 1992) and after (April 1993) the heating season, respectively. he concentrations of the sum of PAH in the pathway soil varied from 3.0 to 1200 ppm in the samples collected before the heating season (October 1992) and 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 (April 1993), respectively. he PCB concentrations were lower than PAH concentrations in all samples; the sum of all target PCB varied from 210 to 1900 ppb in house dust, from 30 to 880 ppb in entryway soil, from 16 to 500 ppb in samples than in entryway samples. imilar PCB concentrations were observed in the pathway soil samples and the foundation soil samples, which were lower than PCB found in entryway soil samples.
