Solid-Phase Extraction Method for the
Quantitative Analysis of Organochlorine Pesticides in Wildlife
Urine
E.E. Petty, J.J. Johnston, and
S.A. Volz
A gas chromatographic method for the analysis of nine organochlorine pesticides in wildlife urine is described. Reversed-phase solid-phase extraction is utilized to extract the organochlorine pesticides from urine. The pesticides are recovered by elution with hexane–ethyl ether (1:1) and quantified by gas chromatography with electron-capture detection. Method detection limits range from 1.4 to 2.7 µg/L. Mean recoveries for all pesticides are 90.6%.
