| Abstract: | Atmospheric particulate matter is routinely analysed for the concentration of the carcinogen benzoa]pyrene (BaP). Benzok]fluoranthene (BkF) has identical spectral characteristics and interferes in the fluorimetric estimation. A simple method for the determination of BaP in the presence of BkF is described. Based on quenching of the fluorescence of BaP by the addition of small amounts of nitromethane, the method can be used for accurate estimation for wide concentration ratios of BaP to BkF ranging from 0.1 to 10.0. |
