Abstract
A relatively inexpensive, expedient, sensitive procedure was developed to separate benzo(a)pyrene (BaP) from other airborne participates collected on glass fiber filters and to quantitatively measure amounts of BaP in the low nanogram range. The technique involved vacuum sublimation, single-dimentional thin-layer chromatography, and spectrofluorometry. Analysis of up to six extracted samples can be completed in less than 2½ hours with a sensitivity down to 1 nanogram. The extraction procedure itelf requires approximately 50 minutes per sample. Total cost for all necessary equipment is approximately $3500.
