| Abstract: | Abstract This paper describes a selective method for the assay of benzo(a)pyrene (BaP) in 24 hour particulate samples. Benzo(a)pyrene is partially separated from the other polynuclear aromatic hydrocarbons via gas chromatography and then is completely resolved optically from traditionally difficult to resolve compounds (benzo(e)pyrene, perylene, benzo(k)fluoranthene) by means of a gas phase fluorescent detector. Ambient air concentrations as low as 20 picograms per cubic meter of air can be assayed with this gas chromatographic - gas phase fluorescent detection system. |
