Abstract

Organochlorine pesticide residues were analyzed in 345 samples of butter purchased from Mexican supermarkets in 1994. Three national brands and one foreign brand were analyzed. Most samples contained residues of gama-HCH (91%), HCB (90%), and p,p'-DDE (88%). Residues of alpha-HCH (63%), p,p'-DDT (42%), beta-HCH (38%), o,p'-DDT (17%), heptachlor epoxide (7%), and endosulfane sulfate (3%) were also detected. Mean values of pesticide residues determined were 0.093 mg/kg fat for total HCH and 0.056 mg/kg for total DDT. Mean values of organochlorine pesticide residues in Mexican butter were comparable with those in a foreign brand.

摘要

1994年对从墨西哥超市购买的345份黄油样本进行了有机氯农药残留分析。分析了三个国产品牌和一个外国品牌。大多数样本含有γ-六氯环己烷（91%）、六氯苯（90%）和p,p'-滴滴伊（88%）的残留。还检测到了α-六氯环己烷（63%）、p,p'-滴滴涕（42%）、β-六氯环己烷（38%）、o,p'-滴滴涕（17%）、环氧七氯（7%）和硫丹硫酸盐（3%）的残留。所测定的农药残留总量中，六氯环己烷的平均值为0.093毫克/千克脂肪，滴滴涕的平均值为0.056毫克/千克。墨西哥黄油中有机氯农药残留的平均值与一个外国品牌的相当。
