Animal feeding stuffs: Methods of sampling and analysis - Determination of OCPs by GC/ECD

This document specifies a gas chromatographic method with electron capture detection (ECD) for the determination of organochlorine pesticides (OCP’s) in animal feeding stuffs.
The method is applicable to animal feeding stuffs with a water content up to about 20 % by weight and oil/fatty samples containing residues of one or more of the following OCP’s, toxaphene and some of their isomers and degradation products:
   aldrin;
   dieldrin;
   chlordane (as the sum of chlordane isomers and oxychlordane);
   dichlorodiphenyltrichloroethane (DDT) (as the sum of isomers op'-DDT, pp'-DDT, pp'-TDE (pp'-DDD), and pp'-DDE);
   endosulfan (as the sum of α-/β-isomers and endosulfan-sulphate);
   endrin (sum of endrin and delta-keto-endrin);
   heptachlor (as the sum of heptachlor and heptachlor epoxide);
   hexachlorobenzene (HCB);
   hexachlorocyclohexane isomers α-HCH (α-BHC), β-HCH (β-BHC), γ-HCH (γ-BHC or lindane);
   photo heptachlor;
   cis- and trans-nonachlor;
A limit of quantification (LOQ) for the mentioned OCPs of 5 ng/g should normally be obtained. However, 10 ng/g applies for heptachlor, aldrin, endrin, dieldrin, and endosulfan (α-/β-- and sulphate). Individual laboratories are responsible for ensuring that the equipment that they use, achieves these limits of quantifications. The LOQs apply to the individual OCPs.

Futtermittel - Probenahme- und Untersuchungsverfahren - Bestimmung von OCP mittels GC-ECD

Dieses Dokument legt ein gaschromatographisches Verfahren mit Elektroneneinfangdetektor (ECD) für die Bestimmung von Organochlorpestiziden (OCP) in Futtermitteln fest.
Das Verfahren ist auf Futtermittel mit einem Wassergehalt bis zu etwa 20 % (Massenanteil) und für öl-/fetthaltige Proben anwendbar, die Rückstände von einem oder mehreren der folgenden OCP, Toxaphen und einige von deren Isomeren und Abbauprodukten enthalten:
 Aldrin;
 Dieldrin;
 Chlordan (als Summe von Chlordanisomeren und Oxychlordan);
 Dichlordiphenyltrichlorethan (DDT) (als Summe der Isomere von op'-DDT, pp'-DDT, pp'-TDE (pp'-DDD) und pp'-DDE);
 Endosulfan (als Summe von α-/β-Isomeren und Endosulfan-Sulfat);
 Endrin (als Summe von Endrin und Delta-Keto-Endrin);
 Heptachlor (als Summe von Heptachlor und Heptachlorepoxid);
 Hexachlorbenzol (HCB);
 Hexachlorcyclohexan-Isomere α-HCH (α-BHC), β-HCH (β-BHC), γ-HCH (γ-BHC oder Lindan);
 Photoheptachlor;
 cis- und trans-Nonachlor.
Für die betreffenden OCP wird eine Bestimmungsgrenze (LOQ) von 5 ng/g angestrebt. Jedoch gilt bei Heptachlor, Aldrin, Endrin, Dieldrin und Endosulfan (α-, β- und Sulfat) eine Bestimmungsgrenze von 10 ng/g. Die einzelnen Labore sind dafür verantwortlich, dass die von ihnen verwendeten Geräte diese Bestimmungsgrenzen erreichen. Die Bestimmungsgrenzen gelten für die einzelnen OCP.

Aliments des animaux: Méthodes d'échantillonnage et d'analyse - Dosage des pesticides organochlorés (POC) par CPG/ECD

Le présent document spécifie une méthode de chromatographie en phase gazeuse (CPG) avec détection par capture d’électrons (ECD) pour le dosage des pesticides organochlorés (POC) dans les aliments pour animaux.
La méthode est applicable aux aliments composés pour animaux, aux huiles et graisses ainsi qu’aux farines de poisson dont la teneur en eau s’élève jusqu’à environ 20 % en masse et aux échantillons d’huiles/de graisses contenant des résidus d’un ou de plusieurs des POC, du toxaphène et de certains de leurs isomères et produits de dégradation suivants :
- aldrine ;
- dieldrine ;
- dichlorodiphényltrichloroéthane (DDT) (isomères de 'op'-DDT', 'pp'-DDT', 'pp'-TDE' ('pp'-DDD') et 'pp'-DDE') ;
- endosulfan (sous forme de somme d’isomères α-/β) ;
- endrine ;
- hexachlorobenzène (HCB) ;
- isomères d’hexachlorocyclohexane α-HCH (α-BHC), β-HCH (β-BHC), γ-HCH (γ-BHC ou lindane) ;
Pour les POC suivants, la méthode considérée est une méthode de dépistage. Une validation interne supplémentaire est requise pour rendre des résultats valides.
- chlordane (sous forme de somme d’isomères de chlordane et d’oxychlordane) ;
- endosulfan-sulfate ;
- delta-kéto-endrine ;
- heptachlor (sous forme de somme d’heptachlore et d’heptachlore époxyde) ;
- photo-heptachlore ;
- cis
- et trans-nonachlore.
Il est prévu d’obtenir une limite de quantification (LQ) de 5 μg/kg pour les POC mentionnés. Cependant, une limite de 10 μg/kg s’applique à l’heptachlore, l’aldrine, l’endrine, la dieldrine et l’endosulfan (α-/β- et sulfate). Il incombe aux laboratoires individuels de s’assurer que les appareils qu’ils utilisent atteignent ces limites de quantification. Les LQ s’appliquent aux POC individuels.
