In order to assess environmental exposure-associated human health risk of dioxin compounds for the population in the vicinity of a municipal solid waste incinerator (MSWI) in Shanghai, the atmospheric samples (n = 24) and soils samples (n = 96) were collected and analyzed to obtain the concentration level, pollution characteristics and seasonal changes of dioxin compounds in environmental medias. The toxicity equivalent concentration range of 2,3,7,8-substituted polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) was 30.9-409 fg WHO-TEQ·m in atmosphere and 0.362-8.55 ng WHO-TEQ·kg in soil. The non-carcinogenic health risk and carcinogenic health risk from PCDD/Fs environmental exposure of people living in the vicinity of the MSWI in Shanghai were all within the allowable range of the US Environmental Protection Agency, which implied that the MSWI in Shanghai did not produce additional risk for the population living in its vicinity.
为了评估上海市某生活垃圾焚烧厂(MSWI)附近人群的二恶英化合物环境暴露相关健康风险,采集并分析了大气样本(n=24)和土壤样本(n=96),以获取环境介质中二恶英化合物的浓度水平、污染特征和季节变化。大气中二噁英和呋喃(PCDD/Fs)的 2,3,7,8-四氯代取代物的毒性当量浓度范围为 30.9-409 fg WHO-TEQ·m,土壤中的浓度为 0.362-8.55 ng WHO-TEQ·kg。居住在上海 MSWI 附近的人群通过 PCDD/Fs 环境暴露所面临的非致癌健康风险和致癌健康风险均在美环保局可接受范围内,这表明上海的 MSWI 并未给附近居民带来额外风险。
