Study of Source Apportionment of PAHs in Atmospheric Suspended Particles in City
摘要
Abstract
[ Objective] The aim was to study PAHs distribution status of atmospheric suspended particles in Jilin City. [ Method] Levels of 16 PAH species in atmospheric total suspended particles of Jilin City at 4 sites during 2005 were determined. Source apportionment results of PAHs were obtained form the factor analysis and multiple linear regression. [Result] The minimum and maximum of 16 PAHs was 0. 006 6 and 137.480 2 ng/m3, respectively. The average summation of the 16 PAHs ( ΣPAHs) was 118.775 6 ng/m3 , the range was 14.239 4 -445.436 5 ng/m3 . The average Σ PAHs of non-heating period was higher than that of heating period. PAHs mainly originated from gasoline and gas-related sources and the contribution rate was 77. 85% , coal-related sources as a second source and the contribution rate was 18.42% , the other sources contribution rate was 3.73%. [ Conclusion] The study provides a theoretical basis for confirming the source of pollutant and draw up planning of atmospheric pollution control.关键词
