对中国大陆12个省、自治区、直辖市母乳中持久性有机氯农药（OCPs）的残留情况进行了调查。二氯二苯三氯乙烷（DDTs）是最普遍的毒剂，其次是六氯环己烷和六氯苯，而氯代氯仿化合物、杀虫剂和灭蚁灵的水平较低。福建省农村地区DDE/DDT比值相对较低，表明福建省农村地区居民接触DDT的时间较近。南方地区母乳中DDTs含量高于北方地区（p < 0.05）。母乳中DDTs浓度与动物源性食品消费量呈正相关，表明该参数可能在影响哺乳期妇女OCPs负担方面发挥重要作用。母乳喂养的婴儿对不同有机氯农药的平均估计日摄入量均低于每日耐受摄入量。(C)2010爱思唯尔有限公司版权所有。
The occurrence of persistent organochlorine pesticides (OCPs) in breast milk samples collected from mothers from twelve provinces in mainland China was investigated. Dichlorodiphenyltrichloroethanes (DDTs) were the most prevalent agent, followed by HCHs and HCB, whereas levels of chlordane compounds, drins and mirex were lower. The relatively lower DDE/DDT ratio in the Fujian rural area suggested more recent exposure to DDT than in other areas. The mean level of DDTs in breast milk from the southern China was higher than those from northern China (p < 0.05). A positive correlation was observed between concentration of DDTs in human milk and consumption of animal-origin food, suggesting that this parameter could play an important part in influencing OCPs burdens in lactating women. The mean estimated daily intakes of different OCPs for breastfed infants were lower than the tolerable daily intake. (C) 2010 Elsevier Ltd. All rights reserved.
