Source Apportionment And Distribution Of Total Suspended Particles During Autumn In Changchun

In the process of rapid urbanization in China, the atmospheric pollution problemof northeast China region become more and more serious due to the long heatingperiod and the growing number of urban population and cars in recent years. Totalsuspended particle (TSP) is the main factor of the urban environmental air pollution.In October2013, this paper sampled in five functional areas of Changchun usingintelligent high flow TSP sampler. The concentration and ingredient of TSP sampleswere researched and analyzed. The research content includes the spatial distributioncharacteristics of TSP; The pollution characteristic of chemical component of TSP;using PMF method for analysis source of TSP. The research aims to analysis of themain source of TSP in Changchun and understand the characteristics and distributionof the pollutant compositions and provide scientific basis for prevention and controlof atmospheric pollution in the region.The conclusion could be drawn by researching the TSP and its chemicalcomponents in the autumn of Changchun that the main sources of cultural andeducational area were the source of waste incineration, coal source, the source ofindustry and the source mixture of construction dust and karaburan., and thecontribution rates were28.8%,39.8%,18.1%and13.4%; the main sources ofresidential area were coal source, the source of waste incineration, construction dust,soil wind dust source and the kitchen smoke source, and the contribution rates were20.3%,34.9%,24.3%,7.7%and12.9%; the main sources of traffic area(1) were soilwind dust source and other sources, industry source and road dust source, automobileexhaust emission source, building source, coal source, and the contribution rates were20.6%,15.7%,41.2%,7.5%and15%; the main sources of traffic area(2) were coal source, the source of waste incineration, the burning of fossil fuels, industry source,soil wind dust source, automobile exhaust emission source, and the contribution rateswere31.2%,12.3%,3.0%,22.3%, and31.2%; the main sources of commercial areawere road dust source and the source of waste incineration, industry source, soil winddust source, coal source, automobile exhaust emission source, and the contributionrates were43.2%,16.2%,6.8%,28.0%and5.8%; and the average concentration ofTSP was268.5μg/m3. The daily average concentrations of five areas were commercialarea> traffic area(2)> traffic area(1)> residential area> cultural and educational area.All areas reach the national secondary standard (300μg/m3) except commercial area.The average concentrations of heavy metals elements in TSP were Ca>Al>Fe>Mg>K>Zn>Mn>Ba>Cr>Cu>Cu>Ni>V>Co>As>Cd. The concentrations of Water-soluble anionic in TSP of cultural and educational area were NO3-> Cl->PO43-> SO42->F->NO2-; and the concentrations of Water-soluble anionic in TSP of residential areawere NO3-> PO43-> Cl->F->SO42->NO2-; and the concentrations of Water-solubleanionic in TSP of traffic area(1) were NO3->PO43->Cl->F->NO2->SO42-; and theconcentrations of Water-soluble anionic in TSP of traffic area(2) wereNO3->Cl->PO43-> F->NO2->SO42-; and the concentrations of Water-soluble anionicin TSP of commercial area were NO3->Cl->PO43->F->NO2-=SO42-. The averageconcentrations of total organic carbon of all areas were cultural and educational area>commercial area> traffic area(2)>traffic area(1)> residential area.
