摘要
为探究阜新市大气颗粒物污染来源,2017年,于阜新市4个不同功能区内进行大气PM2.5及PM10采样,应用富集因子法、地质累积指数法、Spearman相关系数及分歧系数法来解析阜新市大气PM2.5及PM10元素特征及来源。结果表明阜新市大气PM2.5及PM10中元素呈春冬偏高、夏秋偏低的趋势,PM2.5中主要元素为Al、Si、K、Ca、Fe、Na、Mg,PM10中主要元素为Ca、Na、Al、Mg,且PM2.5与PM10中成分谱源解析可能相似,阜新市PM2.5及PM10中污染元素主要来于土壤风沙尘、建筑尘、燃煤与汽车尾气。
In order to explore the sources of atmospheric particulate pollution in Fuxin City in 2017,the atmospheric PM2.5 and PM10 samples were taken in four seasons at four functional areas.The enrichment factor method,geological accumulation index method,Spearman correlation coefficient and divergence coefficient method were used to analyze the element characteristics and sources of PM2.5 and PM10 in Fuxin city.The results showed that the elemental changes in PM2.5 and PM10 in Fuxin City were higher in spring and winter,and lower in summer and autumn.The main elements in PM2.5 were Al,Si,K,Ca,Fe,Na,Mg.The main elements in PM10 were Ca,Na,Al,Mg,the sources apportionment of PM2.5 and PM10 in Fuxin may be similar.The pollution elements were mainly derived from soil dust,construction dust,coal burning and automobile exhaust pollution.
