对应分析在大气颗粒物源解析中的应用研究

摘要

In this paper,we adopt the correspondence analysis melliod to research the source of atmospheric particles in the city ofrnLongyan. The result shows that in the 4 monitoring sites of Longyan city,the main pollution source of Environmental MonitoringrnStation is Kaolin clay and Soil dust; Longyan College and Technology Institution's main pollution source are Motor vehiclernexhausts, Coal dust and Soil dust; moreover, the greatest contribution to Longyan Teacher Training School are Coal dust, Smallrncoal stove dust, Cement product, Cement Limestone Mine and Steel plant dust. The advantages of this method are combining Rrntype factor analysis and Q type factor analysis and synthesizing the relationship of sample and element, which provides a newrnpathway to study the source apportionment of atmospheric particulates.%采用对应分析方法定性研究龙岩市大气颗粒物来源问题.结果表明:龙岩市4个监测点位中龙岩市环境监测站的主要污染源为高岭土矿和土壤风沙尘；龙岩学院与闽西职业技术学院的主要污染源为机动车尾气尘、燃煤尘和土壤风沙尘；龙岩师专的主要污染源为燃煤尘、小煤炉尘、水泥成品、水泥厂除尘器集尘和钢铁厂除尘器集尘.该方法能将R型因子分析和Q型因子分析结合起来,综合体现样品和元素之间的关系,为大气颗粒物源解析提供了一种新的途径.
