Abstract

Organochlorine pesticide residues were analysed in 150 samples of butter collected from several places in the cities of Santa Fe and Rosario (Argentine Republic) over a period of 18 months. Pesticides analysed in butter were: HCH (alpha and gamma isomers), heptachlor and its epoxide, aldrin, dieldrin, and DDT (p,p' DDE, o,p' DDT and p,p' DDT). Most samples contained residues of gamma-HCH (Lindane) and heptachlor (92% and 78%, respectively); alpha-HCH and aldrin were detected in 58% and 55% of samples; dieldrin, heptachlor epoxide, DDT isomers were found in few cases (30%). Mean values of pesticides residues in butter fat were: sigma HCH 0.029 ppm; sigma heptachlor 0.064 ppm; sigma aldrin 0.11 ppm and sigma DDT 0.024 ppm. Residue levels exceeded the limits prescribed by the Food and Agricultural Organization/World Health Organization in only very few cases.

摘要

对从阿根廷共和国圣菲市和罗萨里奥市若干地点采集的150份黄油样本进行了为期18个月的有机氯农药残留分析。分析的黄油中的农药有：六氯环己烷（α和γ异构体）、七氯及其环氧化物、艾氏剂、狄氏剂和滴滴涕（p,p'-滴滴伊、o,p'-滴滴涕和p,p'-滴滴涕）。大多数样本含有γ-六氯环己烷（林丹）和七氯的残留（分别为92%和78%）；在58%和55%的样本中检测到α-六氯环己烷和艾氏剂；狄氏剂、七氯环氧化物、滴滴涕异构体仅在少数情况下被发现（30%）。黄油脂肪中农药残留的平均值为：总六氯环己烷0.029 ppm；总七氯0.064 ppm；总艾氏剂0.11 ppm和总滴滴涕0.024 ppm。只有极少数情况下残留水平超过了联合国粮食及农业组织/世界卫生组织规定的限值。
