中文摘要: 中国自1958年以来开展人工影响天气作业。碘化银作为主要的催化剂,是否会对环境造成影响备受关注。分析了国内外使用碘化银开展人工增雨雪和人工防雹外场试验作业后降水、土壤和湖泊等的Ag+含量,尽管催化后Ag+含量会有不同程度的增加,尤其是地面燃烧炉催化和人工防雹作业,但降水和水库中的Ag+含量远低于饮用水标准。统计了我国外场人工影响天气作业的碘化银用量,结合降水和水库中Ag+浓度观测,认为我国人工影响天气使用的碘化银不会对水资源和环境造成影响。
Abstract:Weather modification operations in China has been carried out since 1958 with silver iodide as the main seeding agent. Whether silver iodide affects the environment has attracted much attention. This paper analyzed the content of silver ions in precipitation, soil and lakes after silver iodide seeding in several countries in the world. The amount of silver iodide used in China was counted, and silver ions in precipitation and in the reservoir were measured. It is found that the silver iodide used for weather modification in China do not affect water resources and the environment.
