Abstract

Abstract

To investigate the seasonal characteristics and sources of water-soluble ions in PM₁ in the southwest suburb of Chengdu, samples were collected during typical seasonal months(January, April, July and October)of 2019, and 8 main kinds of water-soluble ions, including NO₃^-, SO₄^2-, NH₄⁺, Ca²⁺, Cl^-, K⁺, Na⁺, Mg²⁺ in the samples were detected, and finally the mass concentrations and correlation among PM₁ and its water-soluble ions components were analyzed in this research. The result showed that the annual average concentrations of PM₁ and total water-soluble ions were(30.1±12.5) μg/m³ and(8.5±6.2) μg/m³, respectively. Concentrations of ions were, from more to less, in an order of NO₃^->SO₄^2->NH₄⁺>K⁺>Ca²⁺>Cl^->Na⁺>Mg²⁺. Secondary ions(SNA) contributed as high as 90.0% of the total water-soluble ions, and their contributions to PM₁ were different between seasons, which were 35.0%, 23.6%, 22.0% and 17.5% in winter, spring, autumn and summer, respectively. The ratios of NO₃^-/SO₄^2- were 0.9 and 0.6 in spring and summer, and 1.2 and 2.1 in autumn and winter, which revealed that the vehicle sources played an important role in the formation of PM₁ in autumn and winter. The mean values of sulfur oxidation rate(SOR) and nitrogen oxidation rate(NOR) were 0.37 and 0.04, due to the variations in sources and meteorological conditions, respectively, indicating that there was a higher secondary aerosol transformation rate of sulfur. The results of principle component analysis indicated that the secondary inorganic sources, coal combustion, biomass burning and dust were the main sources of the water-soluble ions during the sampling periods.
