This study aims to establish the relationship between the consumption of certain foods and the presence of organochlorine pesticides in human milk. A total of 167 samples of breastmilk were collected. Sample analysis was carried out by gas chromatography with electron capture detector. Pesticide concentrations (op’DDT, pp’DDT, pp’DDE, Σ-DDT, HCB, β-HCH) were grouped by consumption level of fish, dairy products, meat, eggs, and seafood and then were compared to each other. The odds ratio (OR) was calculated between the concentration of pesticides (higher and/or lower than median) and the exposure variable (high consumption). The results indicated low median concentrations of HCB, β − HCH, op’DDT and pp’DDT, whose fluctuations and trends between different frequencies of food consumption were not significant. pp’DDE and Σ − DDT values according to the increase in consumption of fish were significantly increased. Women with high fish consumption have a higher risk of high concentrations of pp’DDE and Σ-DDT (OR: high consumption: 5.6 (1.3–23.6). A protective effect was observed in the consumption of dairy products (β-HCH and op’DDT), meat (HCB), and seafood (pp’DDT). These results suggest that it is possible that the consumption of fish, dairy products, meat, and seafood influences the presence of organochlorine pesticides in the studied population.

这项研究旨在建立某些食品的消费量与母乳中有机氯农药的存在之间的关系。总共收集了167个母乳样品。通过具有电子捕获检测器的气相色谱法进行样品分析。将农药浓度（op'DDT，pp'DDT，pp'DDE，Σ-DDT，HCB，β-HCH）按鱼，奶制品，肉，蛋和海鲜的消费量分组，然后进行比较。计算农药浓度（高于和/或低于中位数）与暴露变量（高消耗量）之间的比值比（OR）。结果表明，六氯代苯，乙型六氯环己烷，op'DDT和pp'DDT的中值浓度较低，不同食物消费频率之间的波动和趋势均不显着。pp'DDE和Σ-DDT值根据鱼的消费量的增加而显着增加。鱼类消费量较高的妇女较高浓度的pp'DDE和Σ-DDT风险较高（或：食用量高：5.6（1.3–23.6）。在食用乳制品（β-六氯环己烷和op “ DDT”，肉类（HCB）和海鲜（pp'DDT）这些结果表明，鱼类，奶制品，肉类和海鲜的消费可能会影响所研究人群中有机氯农药的存在。和海鲜（pp'DDT）。这些结果表明，鱼类，奶制品，肉类和海鲜的消费可能会影响所研究人群中有机氯农药的存在。和海鲜（pp'DDT）。这些结果表明，鱼类，奶制品，肉类和海鲜的消费可能会影响所研究人群中有机氯农药的存在。
