摘要
基于珠江三角洲不同环境介质(水体、大气和土壤)及食物中PCDD/Fs的研究资料,利用VLIER-HUMAAN模型评估了该区域不同暴露途径下PCDD/Fs对人群潜在健康风险。结果表明:珠江三角洲地区人群平均每日摄入PCDD/Fs的量(TDI)为3.312 pg WHO1998-TEQ/kg·d-1,低于世界卫生组织(WHO)组织推荐的容许标准(4 pg WHO1998-TEQ/kg·d-1)。从暴露途径来看,珠江三角洲地区成年人摄入PCDD/Fs的主要途径食物摄取,约占了98.0%。在食物暴露中,水产品是主要途径,约占总摄入量的70%,蔬菜和肉蛋类分别占了16.6%和10.5%,其它较低。水产品是PCDD/Fs引起人群健康风险的重要风险源,应采取有效措施保障水产品质量,同时,调整饮食结构,降低PCDD/Fs暴露的潜在风险。
Based on the environmental multi-media PCDD/Fs concentrations from the Pearl River Delta,potential health risk assessment for different routes of exposure carried out by using VLIER-HUMAAN model.The results showed that total daily intake（TDI） of adult from the Pearl River Delta region exposure to the PCDD/Fs was 3.312 pg.kg-1.d-1.Although it is lower than that recommended the tolerance daily intake value of 4 pg.kg-1.d-1 by the WHO,it has potential human health risk in Pearl River Delta region exposure to PCDD/Fs.For Multi-media exposure routes in the environment,food intake route exposure to PCDD/Fs was the main ways for human,accounted for about 98.0%.Among the food intake items,the fishery product was the main way to the total daily intake,which contributed about 70%.Vegetables,meat and eggs accounted for 16.6% and 10.5%,respectively,the other food items were lower.Fishery products is an important potential risk source for human exposure to PCDD/Fs.Measurement should be carried out to control and protect the quality safety of fishery products.General adult should be adjusted a reasonable food consumption structure.
