摘要
利用单颗粒气溶胶质谱仪(SPAMS),结合哈尔滨市大气污染物排放源谱库对大气污染主要成分进行来源解析,结果表明,秸秆焚烧期间,哈尔滨市环境空气中细颗粒物质量浓度明显上升,生物质燃烧排放源仅低于燃煤和机动车尾气,位列第三大污染源,浓度占总颗粒物浓度的20%。同时,为了探讨秸秆焚烧对哈尔滨市空气质量造成影响的原因,结合气象观测资料,对污染期间气团后向轨迹分析,发现在高空无风不利于污染物扩散的情况下更易加剧哈尔滨环境空气质量污染的程度。
Using single particle aerosol mass spectrometer( SPAMS) in combination with analysis on Harbin source pollutants emission spectrum library main composition of atmospheric pollution source,the results showed that straw burning has increased fine particulate matter concentrations in ambient air in Harbin. Biomass burning emission is ranked as the third largest pollution source after coal and motor vehicle exhaust with a total particulate matter concentrations of 20%. In order to explore straw burning the cause of influence the air quality in Harbin,the research combined with the meteorological observation data and tracks of the pollution. It is found at high altitude without wind is not conducive to the spread of pollutants are more likely to exacerbate Harbin environmental air pollution degree.
