动物饲料 有机氯化物农药残留物的测定 气相色谱法

[中文适用范围]： 本标准规定了测定动物饲料中有机氯农药残留量的气相色谱法。 本方法适用于含有以下一种或多种有机氯农药及其部分异构体和降解产物残留的动物饲料：艾氏剂、op'-DDE、pp'-DDE、op'-DDT、pp'-DDT、狄氏剂、硫丹、异狄氏剂、HCB、α-六氯环己烷 (α-BHC)、β-六氯环己烷 (β-BHC)、γ-六氯环己烷 (γ-BHC)、δ-六氯环己烷 (δ-BHC)、七氯、环氧七氯、op '-TDE (op'-DDD)、pp'-TDE (pp'-DDD) 和甲氧滴滴涕。 这些有机氯农药的测定下限为 0.005 μg/g。 然而，op'-DDT 和 pp'-DDT 的测定下限为 0.01 μg/g，甲氧滴滴涕的测定下限为 0.05 μg/g。 [外文原描述]： 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.
