Animal feeding stuffs - Determination of residues of organochlorine pesticides - Gas chromatographic method (ISO 14181:2000)
This International Standard specifies a gas chromatographic method for the determination of residues of
organochlorine pesticides in animal feeding stuffs.
The method is applicable to animal feeding stuffs containing residues of one or more of the following
organochlorine pesticides and some of their isomers and degradation products: aldrin, op'-DDE, pp'-DDE, op'-DDT,
pp'-DDT, dieldrin, endosulfan, endrin, HCB, _-HCH (_-BHC), _-HCH (_-BHC), _-HCH (_-BHC), _-HCH
(_-BHC), heptachlor, heptachlor epoxide, op'-TDE (op'-DDD), pp'-TDE (pp'-DDD) and methoxychlor.
The lower determination limit for these organochlorine pesticides is 0,005 _g/g. However, the lower determination
limit is 0,01 _g/g for op'-DDT and pp'-DDT, and 0,05 _g/g for methoxychlor.
Futtermittel - Bestimmung des Gehalts an Organochlorpestizid-Rückständen - Gaschromatographisches Verfahren (ISO 14181:2000)
Anwendungsbereich
Diese Internationale Norm legt ein gaschromatographisches Verfahren zur Bestimmung des Gehalts an
Rückständen von Organochlor-Pestiziden in Futtermitteln fest.
Das Verfahren ist anwendbar auf Futtermittel, die Rückstände von einem oder mehreren der folgenden
Organochlor-Pestizide und einigen ihrer Isomere und Abbauprodukte enthalten: Aldrin, op0 -DDE, pp0-DDE,
op0 -DDT, pp0 -DDT, Dieldrin, Endosulfan, Endrin, HCB, a-HCH (a-BHC), v-HCH (v-BHC), g-HCH (g-BHC),
d-HCH (d-BHC), Heptachlor, Heptachlor-epoxid, op0-TDE (op0 -DDD), pp0 -TDE (op0 -DDD) und Methoxychlor.
Die untere Nachweisgrenze für diese Organochlor-Pestizide beträgt 0,005 µg=g. Die untere Nachweis-
grenze ist jedoch für op 0 -DDT und pp 0 -DDT 0,01 µg=g und für Methoxychlor 0,05 µg=g.
