| 摘要: |
| 依据上海市浦东新区2010—2015年2个代表性采样点的142份监测数据，对降水中的化学组成及各组分间的相关性进行了分析。结果表明，监测期间单次降雨的pH值为3.85~6.09，平均值为5.09，属硫酸型/硝酸型复合污染酸雨。其中SO42-和NO3-为主要离子，平均值分别为4.55和3.31 mg/L。通过SPSS统计分析得出，人类生活和生产过程以及海洋源是浦东新区大气降水化学组分的主要来源，但仍存在不同的区域特征。 |

| Abstract: |
| Based on the rainfall monitoring data of 142 precipitation events in Shanghai Pudong New Area from 2010 to 2015, the acid rain chemical composition and its correlation were studied in the paper. The results indicated that the pH values varied from 3.85 to 6.09 and with an average of 5.09. The acid rain at Shanghai Pudong New Area was sulfuric and nitric comprehensive type. Acid rainwater takes SO42-and NO3-as dominant ions, and the average concentration were 4.55 and 3.31 mg/L. According to the SPSS analysis of monitoring data, human activities, industrial source and marine source were the major source of chemical composition in atmospheric precipitation in Pudong New Area, but sub regional character factor was observed as well. |
