A practical method for trace-level analysis of chlorinated organic pesticides by gas chromatography-mass spectrometry

This article discusses a practical and reliable gas Chromatographie procedure that has been successfully developed for the direct measurement of trace levels of lindane, aldrin, heptachlor epoxide, dieldrin, o,p-DDD. and dichlorodiphenyltrichloroethane (DDT). With appropriate sample preparation, this analytical technique can be applied to matrices such as soil, consumer products, fruits, and vegetables.
