统计最近9年丹东市的大气降水资料，pH值平均值为4.66，降水呈酸性，平均酸雨频率为71.5%，酸雨最多最强的是2007年，全年降水34次，其中32次为酸雨，酸雨频率为94.1%，pH值为4.22，降水的酸度很强，降下来的水几乎都成弱酸。测定了市区内主要河流、水库及山泉水的pH值，并进行分析，虽然大气降水pH值较低，但受地表土壤径流、原有地表水、山泉水的中和，各主要河流地表水pH值在7.08-7.56之间，属正常水平，酸性降水对地表水的pH值影响不大。

Statistics in recent 9 years the atmospheric precipitation data of Dandong city, the pH average value is 4.66, acidic precipitation, average frequency of acid rain is 71.5%, the acid rain is the most strongest in 2007, annual precipitation 34 times, including 32 times as acid rain, acid rain frequency was 94.1%, the pH value of 4.22, precipitation acidity is very strong, almost all the water came down into the weak acid. Determination of the urban area of major rivers, reservoirs and mountain spring pH value, and carries on the analysis, Although atmospheric precipitation pH value is lower, but the surface soil and runoff, the original surface water, mountain spring, the main river surface water pH value between 7.08 to 7.56, belong to the normal level, pH value of acid precipitation on surface water. The pH of the acid precipitation effects A little on surface water.
