CHROMATOGRAPHIC TECHNIQUES IN THE ANALYSIS OF ORGANOCHLORINE PESTICIDE-RESIDUES

The review briefly covers the chromatographic techniques used in the a nalysis of organochlorine pesticide residues. The organochlorines rang ing from DDT, HCH, the cyclodiene group and the polychloroterpene grou p have been covered. It endeavours to examine the existing methodologi es and techniques including residue extraction, clean-up, chromatograp hic procedures involved in clean-up and determination and quantificati on of organochlorine residues by gas liquid chromatography from differ ent substrates like food commodities, crops, soil and water.
