[Determination of residues of organochlorine insecticides and polychlorinated biphenyls in cereals, feeds and water].
A semimicro method for the quantitative determination of chloro-organic insecticides (COI) and polychlorinated biphenyls (PCB) in cereals, feed-pellets and water is presented. The extraction of the active compounds is carried out with n-hexane or dichloromethane. The extracts of cereals and pellets are purified by column chromatography with aluminum oxide. A silicagel column is used for the separation of the compounds into COI as well as PCB and hexachlorobenzene. The determination of the active compounds is carried out by gas chromatography using an electron capture detector. Recoveries range between 70 and 108%, except for beta-endosulphan.
