摘要
采用在线单颗粒气溶胶质谱仪对某区域大气细颗粒物PM_(2.5)进行连续在线源解析监测,综合分析了PM_(2.5)的组成成分及来源。该区域8月份PM_(2.5)污染来源综合性较强,主要为机动车尾气源19.7%、扬尘源17.2%、二次无机源15.4%、生物质燃烧源12.9%、燃煤11.3%,此外工业工艺源4.4%、其他11.2%。在线源解析技术为环保管理部门科学制定PM_(2.5)污染防治措施,实现精准管控提供了技术依据。
PM_(2.5) has a small particle size, large area, strong activity, and is easily accompanied by toxic and harmful substances(such as heavy metals, microorganisms, etc.). it has a long residence time in the atmosphere and a long transportation distance, thus affecting human health and atmospheric environmental quality. The air quality improvement target in the "14 th Five-Year Plan" still adheres to the PM_(2.5) indicator. With the narrowing of the fine particle reduction space, how to accurately control and continuously reduce the concentration of fine particles in the area is in a difficult situation. Carrying out source analysis of atmospheric particles and identifying their main sources can provide an important basis for environmental protection management departments to scientifically formulate PM_(2.5) pollution prevention and control measures and precise control. The PM_(2.5) online source analysis technology can divide the collected particulate matter into various sources such as coal, motor vehicles, dust, and biomass combustion within one hour, which overcomes the shortcomings of traditional source analysis methods such as time-consuming and high cost. This article is based on the online single particle aerosol mass spectrometer(SPAMS0515) of Guangzhou Hexin Instrument Co., Ltd. The article introduce the application of online single particle aerosol mass spectrometer in environmental management, through the analysis of PM_(2.5) source in a certain area of Guangzhou in August 2020, analysis of the components and sources of PM2.5 in the area[2].
