本文报道了北京市城区人乳中六六六、滴滴涕(DDT)蓄积水平的动态研究。指出自1983年我国政府决定禁用和停用六六六、滴滴涕以来,人体内六六六水平、P,P′-DDT水平呈逐年下降趋势,而占总DDT含量80％的P,P′-DDE水平起伏不定,作者认为造成这一状态可能与本市使用三氯杀螨醇农药及近年来孕产妇脂性食品比例迅速上升等因素有关。
This article reports the dynamic study on the accumulation of BHC and DDT in human milk in Beijing. Pointing out that since the Chinese government decided to ban and stop the use of 666 and DDT in 1983, the level of P, P’-DDT in the human body has been declining year by year, whereas the level of P, P’- DDE level ups and downs, the authors believe that the resulting state may be related to the use of dicofol pesticides in the city and the rapid increase in the proportion of maternal fat foods in recent years and other factors.
