摘要/Abstract

摘要： 分析2010—2016年济南市区大气VOCs的浓度、组成特征、来源及健康风险。结果表明，2010、2011、2015和2016这4年总VOCs的平均浓度水平相当，2012—2014年总VOCs浓度较上述4年偏低。每年烷烃、烯烃和芳香烃的组分特征存在较大差异。利用主因子分析法对VOCs的来源进行探讨，结果表明所研究的7年间济南市大气VOCs的主要来源种类一致，都是机动车尾气、工业排放、涂料溶剂使用和油气挥发。健康风险评价结果表明，济南市区大气VOCs在所研究7年均不存在致癌风险，但部分年份接近致癌风险水平，应引起重视，加以管控。

Abstract: Atmospheric VOCs samples were collected to investigate the concentrations, compositions, sources, and health risk of atmospheric VOCs in urban Jinan. Results showed that the total VOCs concentrations were comparable in 2010, 2011, 2015, and 2016, while the total VOCs concentration were lower in 2012, 2013, and 2014. Significant differences in the compositional characteristics were found among alkanes, olefins, and aromatics for each year. Main sources of atmospheric VOCs in urban Jinan during the period of the studied 7 years were determined to be motor vehicle exhaust, industrial emissions, paint and solvent using, and oil evaporation by principal factor analysis (PCA). Health risk assessment of atmospheric VOCs was carried out. The results showed that there was no presence of non-carcinogenic risks during the period of the studied 7 years, while lifetime cancer risks were close to the level of carcinogenic risks in some of the years. Attentions should be paid and measures should be taken.
