An improved analytical method was developed for the simultaneous quantification of numerous androgen disruptors-vinclozolin, dichlorodiphenyltrichloroethanes (DDTs), hexachlorocyclohexanes, chlordane, heptachlor, dieldrin, endrin, and aldrin-in fish, followed by GC with tandem MS (MS/MS). Extraction, cleanup, and MS/MS parameters of analytes were optimized. The LOQs of the analytes ranged from 0.3 to 3.7 μg/kg. Reasonable recoveries (73.7-119.2%) were demonstrated at different spike levels with RSDs lower than 12.2%. This method was applied for the analysis of the target analytes in fish samples sold in Hangzhou, China, and DDTs were found to be the predominant contaminants in fish samples.
