摘要
采用理论设计、现场采样、实验室分析和模型计算相结合的方法,对南昌市罗家集工业区可吸入颗粒物(PM10)的来源进行定量解析。在南昌市南昌钢铁责任有限公司监测站和南昌市罗家集何家村监测点采集了(PM10)的样品,同时收集了土壤尘、煤烟尘、冶金尘、建筑尘和机动车尾气尘等五种源样品。用等离子体发射光谱法(ICP)分别测定了受体和源样品中Ca、Mg、A l、As、Fe、Mn、Pb、S、Ti等9种的元素的含量,在此基础上建立了南昌市罗家集工业区源解析的化学质量平衡(CMB)受体模型,并利用CMB模型计算得到各种源对PM10污染的贡献率,分别为:煤烟尘32%、建筑尘22%、冶金尘16%、土壤尘13%、机动车尾气尘8%及其它尘9%。
The apportionment of PM10 in Luojiaji industrial area ambient air of Nanchang city has been performed by academic designing,local samples collecting,laboratory analysis and model calculating etc. The Samples of PM10 were collected at two sites： Nanehang iron＆steel company of Environmental Monitoring Station, Luojiaji industrial area of He village. At the same time ,the samples of five sources were collected, such as soil dust, coal smoke dust, steel dust, building material dust and traffic dust. Nine elements such as Ca,Mg,Al,As,Fe,Mn,Pb,S and Ti in both ambient and sources were measured by ICP -AES. On the basis of the Chemical Mass Balance （CMB） model for Nanchang city was developed. And the contribution rates of five sources to PMto were got through model calculating：coal smoke dust was 32% ,building material dust was 22% ,steel dust was 16% ,soil dust was13% ,tragic dust was 8% ,and other dust was 9%.
