工业区住宅积尘二噁英污染特征及暴露风险
|
摘要
文章选取广东某废弃资源综合利用园区周边的住宅以及远离园区住宅的室内积尘作为研究对象,对积尘中的二噁英进行了研究测定。结果表明,工业区二噁英毒性当量浓度为37.3～174ng I-TEQ/kg,商住区为2.47～18.1ng I-TEQ/kg,工业区浓度均值是商住区的14.5倍,两区域浓度具有统计学显著差异。二噁英的暴露风险显示园区成人和儿童的总暴露风险均值分别为1.19×10~(-6)和8.26×10~(-6),其暴露风险虽然较小,但考虑其长期暴露性,需引起相关部门的高度重视并制订相应的防护措施。
Choosing indoor dust sampled from residences nearby an industrial area for comprehensive utilization of waste resources and those far from the industrial area in Guangdong as study objects. And dioxins in dust have been researched. The results indicated that the toxicity equivalent concentration(TEQ) of PCDD/Fs in the industrial area ranged from 37.3 to 174 ng I-TEQ/kg. The TEQ of PCDD/Fs in the commercial and residential area ranged from 2.47 to 18.1 ng I-TEQ/kg. The average TEQ of industrial area is 14.5 times that of commercial and residential area, and there is a significant difference between the two areas. The exposure risk of dioxins for adults and children in the industrial area was 1.19×10~(-6) and 8.26×10~(-6). Though the risk is low, it is necessary to take protective measures for the population considering its long-term exposure.
