| ANOTACE "ČSN EN 15741 This document specifies a gas chromatographic mass spectrometric (GC-MS) method for the determination of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in compound feeds and feed materials (oils and fats, fish meal). The method is applicable to compound feeds consisting of less than 20 % water by mass and oil/fatty samples containing residues of one or more of the following OCPs and PCBs 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 o,p'-DDT, p,p'-DDT, p,p' TDE (p,p'-DDD), and p,p'-DDE; - endosulfan, as the sum of alpha-/beta-isomers and endosulfan-sulphate; - endrin, as the sum of endrin and delta-keto-endrin; - heptachlor, as the sum of heptachlor and heptachlor epoxide; - hexachlorobenzene (HCB); - hexachlorocyclohexane isomers alpha-HCH (alpha-BHC), beta-HCH (beta-BHC), -HCH (-BHC or lindane); - photo heptachlor; - cis- and trans-nonachlor; - non dioxin-like PCBs (ndl-PCBs), as the sum of PCB 28, 52, 101, 138, 153 and 180. The method has been fully validated by a collaborative trial for the substances and corresponding ranges (µg/kg) noted in Table 1." | ||
