Abstract
Part one: A rapid and reliable procedure is developed for the measurement of the carcinogen benzo(a)pyrene in food. It is a streamlined hybrid of two published methods. These involve ethanalic potassium hydroxide digestion of samples, isooctane extraction, column chromatography on florisil, separation of B(a)P by thin-layer chromatography and measurement of B(a)P by fluorimetry. The recovery of a B(a)P spike of sample is 86.0 + 14.5 % . The procedure which has a limited of detection of 0.05 ng/g (0.05ppb), has been applied to the Human Exposure to B(a)P study.
Part Two: Hexachlorocyclohexane, hexachlorobenzene and some selected PCB congeners were found in treatment municipal wasterwater by capillary GC/ECD analysis. A fin regeneration assay in Striped Bass shows a positive dose-dependent relationship with concentration of the hexachlorinated organic compounds in a series of Treated Municipal Wastewater fractions (TMW). A modified NBS method to analyzed ng/g (ppb)level of chloronate pollutant in fish tissue was developed. It uses concentrated sulfuric acid instead of an LC column to remove the fat interferences in the biological matrix. This simple, low cost and fast sample purification technique has been used for chlorinated pollutant analysis in fish liver. PCBs were found in higher concentration in fish liver than in fish muscle and fish bile.
