空气颗粒物人体暴露来源解析研究进展

Research Advance of Source Apportionment on Personal Exposure to Particulate Matter

颗粒物的短期或长期暴露均会对人体产生不良的健康效应。颗粒物暴露源解析,即定性识别和定量解析颗粒物不同污染源对人体暴露量的贡献,可以提高环境流行病学研究的准确性,并为确定优先控制污染源提供科学依据。该文就颗粒物人体暴露的来源、暴露测量、源解析受体模型的研究现状进行了综述,并提出了颗粒物暴露源解析存在的主要问题和发展趋势。

Both short-term and long-term exposures to airborne particulate matter have been proved to have a major impact on human health. Source apportionment on personal exposure to particulate matter can provide data to help characterize exposure - response relationships for epidemiological studies, and improve risk assessment/risk management. This paper focuses on the research advance of source apportionment on personal exposure to particulate matter, mainly including sources characterization, exposure measurement and receptor models for PM source apportionment. Also, the aspects of further researches on source apportionment of personal exposure are proposed in this paper.
