Voltammetric determination of benzo[a]pyrene in the environment
- Inst. of Water Transport Engineering, Nizhnil Novgorod (Russian Federation)
The increased contamination of the natural environment and the number of oncological illnesses have necessitated constant control of the content of cancerogenic substances, including polyarenes and their indicator benzo[a]pyrene (BP) in water, in the atmosphere, and so forth. Owing to their complexity the cancerogens are usually determined only with respect to BP. Benzo[a]pyrene is determined in extracts by means of the quasiline luminescence spectra in liquid nitrogen temperature using the Shpol`skii effect. The determination of BP by high-performance liquid chromatography is usually conducted on imported research equipment; this method has not yet been used for large-scale analyses. On account of the laborious nature and the insufficient specificity of the methods BP has not been determined systematicly in plants, effluents, and other environmental subjects. The aim of the present work was to develop a procedure for the voltammetric determination of BP in environmental subjects at detection limits 50% below the maximum permissible concentration. 10 refs., 5 figs., 6 tabs.
