Environmental chemistry is an intersectant subject by environmental science and chemistry. Its core problem is to study the chemical transformation and effect of chemical pollutant in environment. The research object of environmental chemistry is a complicated system with many components and mediums. The content of chemical pollutants researched by environmental chemistry is very low. These chemical pollutants distribute extensively, move and transform quickly, and have obvious dynamic change under different space-time conditions.

环境化学是环境科学与化学的交叉学科，它的核心问题是研究化学污染物在环境中化学转化和效应；环境化学研究的对象是一个多组分、多介质的复杂体系；环境化学所研究的化学污染物在环境中的含量很低；化学污染物分布广泛，迁移转化速度较快，在不同时空条件下有明显的动态变化。
