Determination of organochlorine insecticide residues in fatty foodstuffs using a clean-up technique based on a single column of activated alumina.
A method is described for the extraction and clean-up of fatty foods prior to the determination of organochlorine insecticides and related compounds. Clean-up is based on the use of a single 22-g column of activity-4 alumina and the method is capable of routinely determining cyclodienes, BHC isomers and HCB at the 5-10 microgram/kg level and DDT-type compounds at 20-30 microgram/kg level.
