||A method was developed for the determination of neutral and acidic priority pollutant compounds in fish tissue. Priority pollutant compounds are extracted from the fish tissue during homogenization of the tissue in acetonitrile. The acetonitrile extract is isolated from the tissue after centrifuging and placed in a tumbling bottle containing salted water buffered to pH 4, methyl t-butyl ether (MTBE), and petroleum ether. The mixture is equilibrated by tumbling and a portion of the organic layer is isolated after drying over sodium sulfate. The acetonitrile partitioning step serves to remove a portion of the extractable fish lipid material from the priority pollutant compounds. The organic extract is concentrated and the remaining interfering lipid material is removed using a gel permeation chromatography (GPC) procedure.
