【摘要】 应用受体模式的化学元素平衡法,对西宁市市区3个环境监测点环境空气中的总悬浮颗粒物(TSP)进行污染源的源解析,得出4类主要污染源对TSP的平均贡献率:煤烟尘37%,土壤尘27%,建筑尘15 4%,冶炼尘2 9%。同时,对该市市区的地面扬尘也进行了源解析,结果表明地面尘中土壤尘60 2%,建筑尘10 2%,煤烟尘6 0%,冶炼尘1 3%。这与该市环境空气中TSP的构成有所不同。更多还原

【Abstract】 The pollution source of TSP in urban atmosphere of Xining from three environmental monitoring sites were analyzed by the chemical mass balance method(CMB)based on receptor model.The average contribution of four pollution sources to TSP were that:coal smoke dust was37%,soil dust was27%,building dust was15.4%,smelting dust was2.9%.The source of land surface dust was also researched,the average contribution of four pollution sources to land surface dust were that:soil dust was60.2%,building dust was10.2%,coal smoke dust was6.0%,smelting dust was1.3%,this constitution was dif-ferent from TSP in atmosphere.更多还原
