SIMPLIFIED MONITORING PROCEDURES FOR BENZO(A)PYRENE, HEXACHLOROBENZENE AND PENTACHLOROPHENOL IN WATER

Experiments on the uptake and depuration of benzo(a)pyrene (BaP), hexachlorobenzene (HCB), and pentachlorophenol (PCP) in marine organisms required analysis of these compounds on small aliquots of water from the experimental systems. Simplified methods of water analysis were developed which require only a 5. 0 mL sample to measure concentrations of pollutants in the tank ranging from 0. 2 ppb to 200 ppb (ng/g). The use of these simplified monitoring methods is not only applicable to the title compounds but can be extended to other compounds in their respective categories. These methods can also be applied to other aquatic toxicity studies and microbial studies, and to the analysis of waste-water effluents or to other situations where concentrations are in the ppb range.
