A device capable of collecting simultaneously eight equivalent particulate diesel exhaust samples was constructed to test the effect of filter type, extraction solvent and storage condition on the measured concentration of five PAH compounds in diesel exhaust: fluoranthene (Ft), pyrene (Py), benz(a)anthracene (BaA), benzo (k)fluoranthene (BkFT), and benzo(a)pyrene (BaP). An experimental design was used to most efficiently test the variables. A linear model was used to analyze the data. Three main conclusions resulted from the study: 1) Filter type was found to be a significant variable in the determination of BaA, BkFt, and BaP, but not for any of the other compounds. 2) Extraction solvent was the most significant variable for all of the compounds, with dichloromethane providing higher extraction efficiencies than acetonitrile and cyclohexane. 3) Storage condition (storage in glass tubes or storage in the filter cassette) was found to be significant for BaA, BkFT, and BaP; however, the effect was not consistent for all of the compounds. An overall estimate of the precision of the sampling and analytical technique was also estimated from the data. Significance of the data for sampling and analyzing PAH compounds in diesel exhaust is given. 14 references, 4 figures, 4 tables.
