通过观察人奶中有机氯化合物的蓄积水平及动态变化来评价有机氯化合物对环境的污染和对人群健康的影响。［方法］采用与１９８８年环境生物监测研究规划相同的调查方案和监测试法，在长沙市四个行政区内采测了３０岁以下、０～４岁月婴儿乳母的乳样共６１份。［结果］测得６１份人奶样品中，以全奶和奶脂计的中位数水平分别为：六氯苯４． ７１μｇ／ｋｇ和０． １９ ｍｇ／ｋｇ；六六六５１． ５ μｇ／ｋｇ和２． ２０ ｍｇ／ｋｇ；ＤＤＴ ５６．２μｇ／ｋｇ和２． ４３ ｍｇ／ｋｇ。［结论］我省自１９８５年停止使用六六六、ＤＤＴ，经过１３年的时间，长沙地区人体六六六、ＤＤＴ的蓄积水平已由１９８８年的严重污染水平下降了８０％，六氯苯的浓度却以每年６．５％的速度上升，有可能成为继六六六、ＤＤＴ限用和停用后，新的污染物。
The effects of organochlorine compounds on the environment and the health of the population were evaluated by observing the accumulation level and dynamic changes of organochlorine compounds in human milk. [Method] With the same investigation plan and monitoring method as the research plan of environmental biological monitoring in 1988, a total of 61 milk samples from infants aged 30 years and 0 to 4 years were collected and tested in four administrative districts of Changsha City. [Results] The median levels of total milk and milk fat in 61 human milk samples were: HCB4. 71 μg / kg and 0. 19 mg / kg; 5 μg / kg and 2. 20 mg / kg; DDT 56.2 μg / kg and 2. 43 mg / kg. [Conclusion] The province stopped using BHC and DDT since 1985, and after 13 years, the accumulative level of DDT in human body in Bhutan and Liuzhou in the Changsha area has dropped by 80% from the serious pollution level in 1988. HCB However, the rate of increase of 6.5% per year is likely to become the new pollutant after the 666th DDT is restricted and disabled.
