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.
