Abstract

This European Standard specifies a gas chromatographic/mass spectrometric method for the determination of organochlorine pesticides (OC’s) and polychlorinated biphenyls (PCBs) in animal feeding stuffs and oil. The method is applicable to animal feeding stuffs with a water content up to about 20 wt% and oil/fatty samples containing residues of one or more of the following OC’s and PCBs and some of their isomers and degradation products: ? Aldrin; ? Dieldrin; ? Chlordane (= sum of Chlordane isomers and Oxychlordane); ? DDT (= sum of isomers op'-DDT, pp'-DDT, pp'-TDE (pp'-DDD), and pp'-DDE); ? Endosulfan (sum of ?-/?-isomers and Endosulphanesulphate); ? Endrin; ? Heptachlor (= sum of Heptachlor and ?-Heptachlorepoxide); ? Hexachlorobenzene (HCB); ? Hexachlorocyclohexane isomers ?-HCH (?-BHC), ?-HCH (?-BHC), ?-HCH (?-BHC or lindane); ? PCB 28, 52, 101, 138, 153 and 180 (“Indicator PCBs”) and PCB-198, 209. The method is not yet applicable to Chlorocamphene (Toxaphene), a complex mixture of polychlorinated camphenes. Chlorocamphene has a very distinctive chromatographic profile and is easily recognisable by GC/ECD. Positive identification of the toxaphene isomers can be performed by negative chemical ionisation mass spectrometry (NCI-
