摘要

摘要: 为研究沈阳城市表层土壤中多环芳烃(PAHs)污染特征,于2017年9月采集了沈阳城区74个表层土壤样品,检测了土壤中16种优控PAHs的含量,并利用基于蒙特卡罗模拟的概率风险评价模型定量评估了其健康风险。结果表明:沈阳城市表层土壤中PAHs含量为283~21821 μg/kg,平均值为2370 μg/kg;与国内外其他城市土壤污染状况相比,沈阳城市表层土壤中PAHs的污染较为严重。健康风险评价结果表明,沈阳城市表层土壤中PAHs对儿童和成人造成的总致癌和非致癌风险均处于可接受的水平;其中,苯并[a]芘是致癌风险的最主要贡献物质,芘、荧蒽和菲是非致癌风险的最主要贡献物质。

Abstract: In order to study the pollution characteristics of polycyclic aromatic hydrocarbons (PAHs) in urban top soil of Shenyang, 74 urban top soil samples were collected from the urban area of Shenyang in September 2017, the concentrations of 16 prior PAHs were determined, and the health risks were evaluated by probabilistic risk models based on Monte Carlo simulation. The results showed that, the concentrations of 16 PAHs ranged from 283 to 21821 μg/kg, with an average concentration of 2370 μg/kg. Compared with other researches, the pollution extent of PAHs in urban top soil of Shenyang was serious. The results of health risk assessment showed that, the total carcinogenic and non-carcinogenic risks caused by PAHs for children and adults were presented at an acceptable level. Among them, benzo[a]pyrene was the key contributor for carcinogenic risk, while pyrene, fluoranthene and phenanthrene were the key contributors for non-carcinogenic risk.
