本研究调查了北京、沈阳、中国等地人群通过食用各类食品摄入DDTS和HCHs的时间趋势及相关的健康风险。2005/2007年度的滴滴涕和六氯环己烷的估计膳食摄入量分别比1992年和20世纪70年代低了近一个数量级和两个数量级，显示了中国食品中滴滴涕和六氯环己烷被禁止使用后的历史下降。20世纪70年代和1992年不同食物对滴滴涕和六六六总摄入量的相对贡献与2005/2007年有很大不同，主要是由于食物的浓度差异显著和人口饮食习惯的变化。根据危害指南，得出的结论是，2005/2007年这两种杀虫剂的摄入量可能不会对人类健康造成不利影响。
The temporal trends in daily dietary exposure of the populations in Beijing and Shenyang, China to DDTs and HCHs through consumption of various food categories and the associated health risks were investigated in this work. The estimated dietary intakes of DDTs and HCHs in 2005/2007 were almost one and two orders of magnitude lower than those in 1992 and in the 1970s, respectively, revealing the historical decrease of DDT and HCH in Chinese foods after their applications were banned. The relative contributions of different foodstuffs to the overall intakes of DDTs and HCHs in the 1970s and in 1992 were very different from those in 2005/2007, mainly due to the remarkable concentration variance in foodstuffs and changes in diet habit of population. According to the hazard guidelines, it is concluded that intakes of these two pesticides in 2005/2007 may not exert adverse effects on human health.
