The preliminary study of the PM1 main components and of their seasonal variation using a linear parametric model

摘要: This study presents the mass concentration PM1(aerosol particles with an aerodynamic diameter below 1μm) together sixteen related trace elements (i.e. Al, Ca, Cd, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, Pb, S, Ti, Zn) measured during Summer and Winter periods in a characteristic anthropized area. Soil, Sulfate, total-metal-oxide (TMO) carbonaceous material (CM) masses were evaluated considered as main components of PM1. All variables log transformed to smooth extreme recording influence. A linear parametric model was estimated asses influence on PM1 evaluate possible differential effect observation the components contribution. Results showed that CM, Soil TMO explained about 44.32%, 33.56%, 11.4% 0.2% total variance PM1, respectively. The contributions Sulfate significative error 5%. contribution 10%. contributed significant difference between Winter, whereas non Winter. Therefore, which mainly anthropogenic origin 78% variance, component natural variance. differently result suggested seasonal sources activities for these components.
