Abstract

Membrane samples of atmospheric PM₁ were collected and their chemical components were analyzed during typical months of each season in 2015 at Chengdu downtown area, to investigate the pollution characteristic caused by atmospheric PM₁. Results showed that average mass concentration of the atmospheric PM₁ at Chengdu downtown area during 2015 was 51.97μg/m³. Main backbone of the atmospheric PM₁ was appeared as water soluble total ion (TWSI), which accounting for 44.56% of the total atmospheric PM₁. An average NO₃^-/SO₄^2-of 0.66 (<1) indicating a greater contribution of stationary sources in atmospheric PM₁ pollution than that of mobile sources. A much faster conversion of sulfur than nitrogen was proved by the higher SOR of 0.34 (than NOR of 0.07). The weaker correlation of organic carbon (OC)/elemental carbon (EC) in summer (R²=0.66) than other seasons (R²=0.89), indicated that the sources of OC and EC in summer was widely, while in other seasons were fixed. Source analysis results showed that there were six kinds of main source of the atmospheric PM₁ at Chengdu downtown area in 2015, which were secondary nitrates, secondary sulfates, vehicle exhaust and biomass combustion, coal dust, dust source, and metallurgy.
