| Abstract: | In order to characterize the seasonal dynamics and regional distribution of major water-soluble ions in atmospheric environment,aerosols were sampled during summer and winter of 2006,and spring and autumn of 2007 in Changjiang River Estuary and East China Sea and analyzed by ion chromatography.The results reveals that K+ and Ca2+ in the atmospheric aerosol has significant seasonal variations,showing a trend of decreasing from the shore to open sea,while Na+ and Mg2+ shows obvious differences of regional dis... |
