The concentration characteristics of water-soluble ions in atmospheric fine particulate matter PM2.5 in Shenyang City were studied. Correlation analysis was carried out on the tested components. The results showed that SO42- and NO3- in the water-soluble ion concentration of PM2.5 in Shenyang City. The three ions of NH4+ account for a higher total ion concentration, accounting for 35.2%, 34.7%, and 11.6%, respectively. It was found that due to the unique terrain and climate of Shenyang, the spring pollution was more serious. Correlation analysis showed that the main forms of water-soluble ions in PM2.5 in Shenyang City were NO3NH4, KNO3, MgSO4, CaSO4 and so on.
