The factors for environmental pollution can be classified into three catagories: physical, chemical and biological and the chemical pollution covers about 80% to 90% among them. The development in chemistry is follwed by a series of environmental problems.
The factors that cause environmental pollution can be classified into physical, chemical and biological three aspects, and among them by chemicals pollution accounted for about 80% -90%. With chemical development, a series of environmental problems to follow.
There are three categories of causes that create environmental pollution: physical, chemical, biological. Among them, pollutions by chemical substances cover about 80-90% of all pollutions. As chemistry continues to develop, it creates a series of environmental problems.
