Abstract

In this study, PM_2.5 samples were collected in Beijing and Shijiazhuang in winter, 2014. The characteristics of PM_2.5 and its water-soluble ions component were investigated. Then the WRF-CAMx modeling system was developed to examine the regional transportation impact of PM_2.5 and secondary inorganic species within the same period of sample collection. The result showed the concentration of PM_2.5 in Beijing during sample collecting period was (116.6±87.0)μg/m³. Total water-soluble ions concentration was (45.3±40.6)μg/m³, and the concentration of SO₄^2-, NO₃^- and NH₄⁺ were (13.3±13.6)μg/m³, (14.8±15.1)μg/m³ and (9.1±7.2)μg/m³, respectively. The PM_2.5 pollution in Shijiazhuang was more serious than Beijing, which could be found through the result that the concentration of PM_2.5 in Shijiazhuang was (267.7±166.7)μg/m³. The concentration of total water-soluble ions, SO₄^2-, NO₃^- and NH₄⁺ were (111.8 ±104.3)μg/m³, (36.6±36.5)μg/m³, (28.5±29.3)μg/m³ and (25.5±29.8)μg/m³, respectively. SOR and NOR in two sites was 0.12, 0.10 (Beijing) and 0.11, 0.14 (Shijiazhuang), respectively. Atmospheric oxidation effect in winter was relatively weaker. Heterogeneous oxidation was the mainly mechanism of aerosol reaction. The simulation results showed the contribution of regional transportation to urban area of Beijing and Shijiazhuang in January was 28.1% and 28.3%, respectively, and the increased regional contribution were found during heavy pollution period. The regional transportation contribution of NO₃^- was much higher than that of SO₄^2- in both sites.

Key words： PM_2.5 water-soluble ions secondary reaction ratio WRF-CAMx regional transportation
