摘　　要：在上海市区设置五个采样点监测上海市区 1 998～ 1 999年的酸雨状况 ,并采用单柱离子排斥 -阳离子交换色谱系统同时分离和测定了雨水中的阴、阳离子。结果表明 ,上海市区 1 998、1 999年的酸雨出现频率分别为 2 4 .2 %和 2 1 .0 %。酸性降水主要集中在梅雨季节 ,说明天气条件的变化已成为上海市区酸雨的主要外因。作为雨水中的主要酸性阴离子 ,1 999年与 1 998年相比 ,SO2 - 4 的平均浓度有所降低 ,而 NO- 3 的平均浓度则有明显增加。Five sites were set up for sampling rainwater in Shanghai A simple, selective and sensitive method was used for simultaneously determining ions in rainwater by single column ion exclusion cation exchange chromatography with conductometric detection The frequency of acid rain in 1998 and 1999 were 24 2% and 21 0%, separately Acid rain mainly dropped in the plum rains season As the main acidic ions in rainwater, the average of SO 2- 4 concentration in 1999 was less than that in 1998, and the average of NO - 3 concentration in 1999 was more than that in 1998
