This material is harmful to the environment, water and atmosphere of the pollution caused by organic acid, can be easily in atmospheric chemistry, and the atmosphere in the physical change form acid rain. So when PH value to 5 below in animal and plant cause serious harm, fish breeding and development be severely affected soil and water, river basin in the sediment can be dissolved metal into the water poisoning fish. The acidification of the water in the composition of the aquatic organisms structure changes of algae and fungi, acid increased, while those with roots plants, bacteria and vertebrates, reduce the decomposition of the organic matter rate to decrease. Will lead to serious after the acidification of the lakes, rivers, fish reduce or death in.
