| 摘 要： | 为搞清实施人工影响天气后,所用碘化银催化剂是否对环境造成污染这一问题,利用2002年12月至2003年3月在北京尖子山,使用碘化银地面发生器在人工增雨雪试验中,对4次人工降雪过程所采集雪水样品进行了Ag 测定及其他化学组分分析。发现雪水中Ag 浓度在不同天气过程中变化明显,变化与催化剂数量间没有直接线性关系,所测的Ag 浓度远低于我国生活饮用水标准。雪水化学特征明显,雪水中阴离子浓度最高是SO42-、NO3-,阳离子Ca2 、NH4 浓度最高。与污染较重的雾水相比,雪水中的诸离子浓度远低于北京地区雾水所测值。

| Abstract: | In order to explore whether AgI will pollute the environment after seeding,snow water sample data were collected in the snow enhancement experiment by using a ground AgI generator from December 2002 to March 2003 at Jianzishan Mountain of Beijing.Ag concentration and other chemistry components in the snow water are analyzed.The results show that Ag concentration varied obviously under different weather patterns.There is no direct linear relation between Ag concentration change and catalyst amount.The Ag concentration in the snow is far below the drinking water standards of China.There are obvious chemical characteristics in the snow water: the concentrations of SO2-4 and NO-3 are the highest in the anions,and the concentrations of Ca2 and NH 4 are the highest in the cations.The total ion concentration in the snow water is much lower than that of the heavily polluted fog water observed in the Beijing area. |
