Abstract

Nanjing, an important city in the Yangtze River Delta region, faces serious air pollution problems, especially particulate pollution. PM_2.5 can reduce atmospheric visibility and affect climate change, as well as adversely affect human health. Therefore, it is very necessary to monitor the components of PM_2.5. In order to study the component characteristics and sources of PM_2.5 in the northern suburbs of Nanjing, 191 PM_2.5 samples were collected and quantitatively analyzed for water-soluble ions (WSI), organic carbon (OC), elemental carbon (EC) and water-soluble organic carbon (WSOC). The annual average mass concentrations of OC, EC, and WSOC were 5.30 μg m^-3, 0.96 μg m^-3, and 3.09 μg m^-3, respectively. The variation characteristics of their seasonal abundance were basically the same, which reached the maximum in winter and the lowest in summer. Based on the ratio of organic carbon to elemental carbon, we find that the air in the northern suburbs of Nanjing is affected by coal burning, exhaust emissions and biomass combustion. The annual mean mass concentration of WSI in PM_2.5 was 23.00 μg m^-3, and the order of seasonal concentration was winter > autumn > spring > summer. The WSI in PM_2.5 are mainly SO₄^2-, NO₃^-, and NH₄⁺. Through the concentration ratio of NO₃^-/SO₄^2-, we found that mobile sources were the main sources of pollution in autumn and winter, while stationary sources were the main sources of pollution in summer. Through the iterative calculation of PMF, five sources of PM_2.5 are determined, which are second generation (37.5%), traffic-related source (36.7%), combustion source (9.6%), marine source (8.5%), and industrial emissions (7.7%). In different seasons, PM_2.5 is significantly correlated with SO₄^2-, NO₃^-, and NH₄⁺, indicating that PM_2.5 mainly comes from secondary generation.
