摘要
在贵阳市某工业园区对环境空气中VOCs进行样品采集和分析。结果表明:研究区域共检测出13种VOCs物质,VOCs平均质量浓度为416.69μg/m3,其中芳香烃平均质量浓度占96.7%,是研究区域环境空气中VOCs的主要成分,对OFP的贡献最为显著(98.42%)。健康风险评价结果显示:6种芳香烃化合物的非致癌风险危害熵值(HQ)为0.0123~0.525,对暴露人群不存在非致癌风险,但其非致癌总危害指数(HI)为1.46,对暴露人群有潜在的非致癌风险;苯的致癌风险值(Risk)为1.23×10-4,对暴露人群有潜在的致癌风险。
The samples of atmospheric VOCs were collected and analyzed in an industrial park of Guiyang. The results showed that 13 kinds of VOCs were quantified in the study area,and the mean of the mass concentrations of VOCs were 416. 69 μg/m3,in which the mean concentrations of aromatic hydrocarbons accounted for 96. 7%. That meant the aromatic hydrocarbons were the main components of VOCs in the atmosphere in the study area,and played the dominant roles for OFP（ 98. 42%）.The health risk assessment showed that the hazard quotient of 6 kinds of aromatic hydrocarbons ranged from 0. 0123 to 0. 525,and had no risk of non-cancer effect on the exposed population,but the hazard index was 1. 46,may cause appreciable noncarcinogenic risk on the exposed population; the cancer index exposed to benzene was 1. 23 × 10-4,may cause potential risk of cancer on the exposed population.
