阿特拉津生产废水排放对水稻危害的风险分析

阿特拉津是目前世界上广泛使用的除草剂之一，在我国主要使用于东北和华北地区。近年来我国一些地区接连发现了灌溉含有阿特拉津河水的水稻疫苗受害事件。以河北省宣化农药厂的生产工艺为例，通过使用概率评价的方法，进行了阿特拉津对水稻危害的风险分析研究结果表明，这种风险不仅与工厂废水中阿特拉津的排放有关，而且还取决于河水的流量及其风险率所得结果与该厂历史上的实际情况相吻合。

Analysis of Atrazine Production Producing Wastewater Risk to Seedling Stage Rice

Atrazine is one of the herbicides used widely in the world at the present and used mainly in Northeast and North China areas. In recent years some places continually occurred accidents that seedling stage rice was damaged due to irrigate river water containing atrazine in China. In this paper, to take the production procedure of Xuanhua pesticide manufactory, Hebei Province,as example, the analysis of atrazine producing wastewater risk to seedling stage rice was studied with use of probabilistic assessment techniques. The results show that the risk not only is related to atrazine discharge from factory, but also dependent on river flow and its risk probability. The results have a good agreement with state of factory history.
