Summary:An efficient screening method capable of recovering base/neutral and acidic organic priority pollutants from sediment samples has been developed and applied to field samples. The procedure involves solvent extraction with sonication, solid-phase extract clean-up, and quantitative analysis by gas chromatography-ion-trap mass spectrometry. The method was applied to over 300 samples of both freshwater and marine sediments. Quality control data indicate that the accuracy and precision of the method are comparable to those of other techniques reported in the literature, including US Environmental Protection Agency methods for waste samples. The spatial variation of organic pollutants in adjacently collected sediments was found to be greater than anticipated and does not appear to be a result of analytical imprecision.
