龙岩市大气环境中可吸入颗粒物源项分析

在2009年9月至2010年3月期间,分秋冬春3个季节对龙岩市4个监测点大气中PM10含量及其各类污染源进行了系统采样和分析工作。然后,利用回归分析和假设检验结合的方法,对源和受体中的无机组分进行了研究。结果表明,在秋季,除了龙岩学院的主要污染源是道路尘外,师专、龙岩监测站和闽西大学大气污染的主要来源都是扬尘;在冬季,龙岩学院和师专的主要污染源是汽车尾气、扬尘和钢铁厂,监测站和闽西大学则是扬尘、汽车尾气和水泥厂;在春季,4个监测点位的最主要污染源是扬尘,其余有所不同。该研究结果有利于制定相应的PM10污染防治规划,提高规划的针对性和有效性,为大气污染防治提供科学依据。

Source Analysis of the Components in Inhalable Particulate Matter in Ambient Air of Longyan City

From September 2009 to March 2010,the content of PM10 and its various types of pollution sources were collected and analyzed respectively at four monitoring points in Longyan City in three seasons(autumn,winter and spring).Then the inorganic components of source and receptor were studied with regression analysis and hypothesis testing.The results showed that in autumn the main source of air pollution in Teachers College,Longyan monitoring station and Minxi University was dust,and the main source of Longyan University was road dust;in winter,the main sources of air pollution in Longyan University and Teachers College were vehicle exhaust,dust and steel plant,while those of Longyan monitoring station and Minxi University were dust,vehicle exhaust and cement plant;in spring,the main sources of the four sites were dust,the other major sources were different.The results of this paper were helpful in formulating the corresponding prevention and control planning of PM10,raising relevance and effectiveness of the program,and it provided a scientific basis for the prevention and control of atmospheric pollution.
