烟台市大气PM_(2.5)在线源解析监测研究

Analysis of PM_(2.5) Source On-line Monitoring in Yantai

本文采用在线源解析质谱监测的方式,对烟台市大气中PM_(2.5)的污染水平、成分及其来源与贡献进行了研究分析,结果表明,烟台市2017年全年颗粒物首要污染源为燃煤(23.5%),其他污染源有机动车尾气(23.1%)、生物质燃烧源(14.3%)、二次无机源(13.0%)、工业工艺源(11.4%)等。在线源解析方式操作简单,使用方便,时间分辨率高,可以为政府部门大气污染防治和重污染天气应对提供及时高效的数据支撑。

The atmospheric PM2. 5 pollution level,components and their sources and contributions of Yantai were analyzed online with mass spectrometry monitoring method in this paper. The analytic results show that the main pollution source was coalfiring（ 23. 5%）. Other pollution sources were automotive exhaust（ 23. 1%）, biomass burning（ 14. 3%）, secondary pollution sources（ 13%） and industrial source（ 11. 4%） etc. With the advantages of simple operation,easy use and high temporal resolution,on-line source analyzing can provide timely and effective data support for government departments to prevent air pollution and cope with heavy pollution.
