摘要
A gas chromatographic method for the analysis of nine organochlorine pesticides in wildlife plasma is described. Reversed-phase solid phase extraction is utilized to extract the organochlorine pesticides from plasma. This is followed by a normal phase solid phase extraction clean-up as the pesticides are recovered by elution with hexane:ethyl ether (1:1) and quantified by gas chromatography/electron capture detection. Method limits of detection range from 7.0-25 mu g/L. The mean recovery for all pesticides is 81%.
