Abstract PM_2.5 samples were collected at four cities (Xuzhou, Dongshan, Nanjing and Shouxian) from December 13th 2016 to January 5th 2017 to investigate the composition and source of water-soluble ions in this study. Moreover, the time variation of these ionic species coupled with the local meteorological conditions was analysed to shed light on the haze formation and dissipation mechanism in the Yangtze River Delta Region (YRD). The results revealed that: during the observation period, the average mass concentration of PM_2.5 in Xuzhou was 171.5μg/m³, which was much greater than the average mass concentration in the other three sites. The most important ionic components were NO₃^-, SO₄^2-, NH₄⁺, Cl^- and Ca²⁺. The variations of ionic components were due to the combined effects of emissions and weather systems. Under the influence of the same weather system, the pollutant concentration varied consistently in different areas of YRD. Under the static weather condition without obvious regional transport, the ion concentrations were mainly affected by the local sources. Xuzhou was mainly affected by the coal. Nanjing was mainly affected by the chemical industrial source. The major component in both Xuzhou and Nanjing was SO₄^2-. Dongshan is surrounded by the lake on three sides, and Cl^- increased significantly to 6.12μg/m³ under the static weather condition. Shouxian was mainly affected by the ammonia emissions of local agricultural activities, and NH₄⁺ increased significantly to 25.09μg/m³. The concentration of PM_2.5 and water-soluble ions of four sites varied with time consistently. When YRD was controlled by the weak high pressure accompanied with the uniform pressure field, this weather pattern was favorable for pollutant accumulation. The principal component analysis indicated that secondary formation had the largest contribution to PM_2.5 concentration, with the contribution rates of 39.83%, 42.27%, 50.56% and 38.40% at Xuzhou, Nanjing, Dongshan, Shouxian, respectively.
