Geochemical Principles and Methods of Assessment of Surface Water Environmental Impact on Sensitive Zones

摘要

This paper describes how to carry out environmental impact assessment in an envi- ronmentally sensitive zone. The principles, he train of thought and methods are proposed in this paper. We have made the water environmental impact assessment on the engineeing pro- ject of technical reforms in Guiyang Battery Mill. The basis for engineering construction and environmental protection in this mill has been laid dawn.
