【Abstract】 Based on the data of wet depositions from the west Pacific, middle Pacific, Venezualan, Corsica and Qingdao. This study reveals major factors/processes influence the chemical compositions of rain water in these regions. Concentration of Ca in rain water is greatly affected by the continental materials. Na and Cl mainly come from the sea salt, i. e. , they are contributed through washing sea salt aerosol in atmosphere. Elevated value of SO42- is considered from the contribution of man-made pollution and volcanic events etc. Whereas NO2 is mainly supplied from NO2 that are both natural and man-made pollutions. Consequently H2SO4 and HNO3 are the major causes of acid rain, CaCO3-CO32- system (calcite dissolution) could buffer rain acidity and increase pH.更多还原
