| 摘 要： | 庐山春季高山降水和云雾水均已严重酸化，所采样品的ｐＨ值全部小于５．６，主要酸性物质是硫酸，硝酸占次要地位；云雾水中离子浓度高于降水，且酸度强于降水；对不同相态降水的比较表明，固相降水组成比雨不高２－６倍，但ｐＨ值比雨水高０．６。而氧化性物质Ｈ２Ｏ２在降水中浓度高于云雾水中浓度，液相降水中浓度于固相降水。

| Abstract: | The precipitation and cloud water in spring at the top of Lushan was acidified seriously, the pH value of all samples was below 5. 6, the major acid was sulfuric. The concentration of ions in cloud water was higher than that in precipitation. The concentration in solid precipitation was higher than that in liquid precipitation by 2-6 factors, the pH value of solid precipitation was higher by 0. 6. But H2O2 concentration in precipitation is higher than that in cloud water and it is higher in liquid precipitation than that in solid precipitation. It is speculated that the acidification of precipitation was caused by the integration of long-distance transport and scavenging of local pollutants. |
