摘要: 针对太湖区域环境中DDTs和HCHs混合暴露的健康危害,基于对居民DDTs及HCHs不同途径暴露量的分析,通过建立DDTs及HCHs的PBPK模型,分析其在人体内的累积分布过程,并应用内效应综合危害指数评价其混合暴露的健康风险。结果表明,居民健康风险度分别为0.147~2.499(男性)和0.138~2.223(女性),超过可接受风险的概率分别为24.6%(男性)和16.5%(女性)。相较于传统的混合健康风险评价方法(HI法),基于PBPK模型的内效应综合危害指数法(HI tissue-dose )更能反映混合健康风险的发展趋势。

Abstract: Based on the investigation of residents DDTsHCHs mixed exposure via different ways in Taihu Lake region, a physiologically based pharmacokinetic (PBPK) model was built to analyze the distribution and accumulation processes of the pesticides in human tissues, and a tissue dose hazard index was used to assess the health risk of the mixed exposure. For the male and female residents, their health risk index was 0.147-2.499 and 0.138-2.223, and the probability of exceeding the acceptable risk was 24.6% and 16.5%, respectively. Comparing with the traditional mixed health risk assessment method,  i.e ., HI method, the PBPKbased tissue dose hazard index (HI tissue-dose ) could better reflect the development trend of mixed health risk.
