Abstract
A procedure is described for the determination of fenitrothion (O,O-dimethyl O-4-nitro-3- methylphenyl thiophosphate) residues in fish tissue, water, and sediment. Fish and sediment samples are extracted with ethyl acetate and cleaned up by partitioning with hexane and passing through Florisil columns. Extracts are analyzed by gas-liquid chromatography, using a flame photometric detector to determine phosphorus and sulfur. Mean recoveries of triplicate analyses of fish muscle samples spiked with 0.1-5.0 μg fenitrothion/g were 94舓110%.This publication has 0 references indexed in Scilit:
