High concentrations of persistent chlorinated hydrocarbon pesticide residues were detected by gas-liquid chromatography with an electron capture detector (3H), in eggs of hens collected from Lucknow under the pesticide monitoring programme. The present study reveals extremely high contamination of eggs, particularly with DDT and HCH residues. The eggs may be an important source of DDT and HCH build-up in the human body. Residue levels of p,p'-DDT and its metabolites p,p'-DDE and alpha, beta and gamma-isomers of HCH were higher in eggs of poultry-farm hens compared to those of domestic hens. Egg yolk contained higher levels compared with egg white, because of the lipophilic nature of pesticides and the high lipid content in the yolk. Average levels of total DDT and HCH residues in the yolk and white in the whole egg of a poultry-farm hen were found to be 18.5 and 4.6 micrograms respectively, whereas the average levels were 7.4 and 4.1 micrograms, respectively, in the whole egg of a domestic hen.
在农药监测项目中，通过配有电子捕获检测器（³H）的气液色谱法，在从勒克瑙收集的母鸡产蛋中检测到了高浓度的持久性氯代烃农药残留。本研究表明鸡蛋受到了极其严重的污染，尤其是滴滴涕（DDT）和六氯环己烷（HCH）残留。鸡蛋可能是人体内滴滴涕和六氯环己烷积累的一个重要来源。与家养鸡的鸡蛋相比，家禽养殖场母鸡产蛋中的对，对'-滴滴涕及其代谢物对，对'-滴滴伊以及六氯环己烷的α、β和γ异构体的残留水平更高。由于农药的亲脂性以及蛋黄中高含量的脂质，蛋黄中的残留水平高于蛋清。在家禽养殖场母鸡的整个鸡蛋中，蛋黄和蛋清中滴滴涕和六氯环己烷总残留的平均水平分别为18.5微克和4.6微克，而家养鸡整个鸡蛋中的平均水平分别为7.4微克和4.1微克。
