A method for determining benzo(a)pyrene in air samples collected on glass fiber filters in occupational areas.

by Sollenberg J

Benzo(a)pyrene was analyzed in air samples collected on glass fiber filters in occupational areas. Vacuum sublimation, thin-layer chromatography on acetylated cellulose, and fluorescence scanning of the thin layer plate were performed. The recovery of the method was estimated by an isotope dilution technique using 3H-benzo(a)pyrene. Special equipment was constructed for sublimation. The detection limit for authentic samples was found to be about 10 pmoles per filter.
