Chromatographic techniques in the analysis of organochlorine pesticide residues.

The review briefly covers the chromatographic techniques used in the analysis of organochlorine pesticide residues. The organochlorines ranging from DDT, HCH, the cyclodiene group and the polychloroterpene group have been covered. It endeavours to examine the existing methodologies and techniques including residue extraction, clean-up, chromatographic procedures involved in clean-up and determination and quantification of organochlorine residues by gas liquid chromatography from different substrates like food commodities, crops, soil and water.
