This European Standard specifies a gas chromatographic method with electron capture detection (ECD) for the determination of organochlorine pesticides (OCs) in animal feeding stuffs.
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, toxaphene and some of their isomers and degradation products:
- Aldrin;
- Dieldrin;
- Chlorocamphene (Toxaphene);
- 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 alfa-/beta-isomers and Endosulfan-sulphate);
- Endrin;
- Heptachlor (= sum of Heptachlor and beta-Heptachlorepoxide);
- Hexachlorobenzene (HCB);
- Hexachlorocyclohexane isomers alfa-HCH (alfa-BHC), beta-HCH (beta-BHC), γ-HCH (γ-BHC or lindane);
- Photoheptachlor;
- Cis and Trans nonachlor
The limit of quantification for the mentioned OCs is 5 ng/g in general. However, 10 ng/g applies for Heptachlor, Aldrin, Endrin, Dieldrin, and Endosulfan (alfa-, beta- and sulphate). Individual laboratories are responsible to ensure that the equipment they used will achieve these limits of quantifications.
