ENVIRONMENT is usually undertood to mean the surface. AFFECTS An Organism During ITS LIFETIME. From a Human Perspective, Environmental Issues Involve Concerns About Science, Nature, Health, Employment,Profits, POLITICS, ETHICS, and Economics.
The general discussion is a natural environment, which can be divided into: living environment; geographical environment; geological environment; cosmic environment.The environment of environmental global chemistry research mainly refers to the geographical environment, which refers to the four geochemical systems that are closely related to human survival activities, namely atmospheric systems, water systems, soils and biological systems, and surface rock rings systems.
Native environment or first environment (environment of nature):Refers to the natural environment formed by the Earth’s own formation process and subsequent long -term geological history, and its basic composition elements formed under the action of various geological strength.The material component characteristics and structural characteristics of this type of environment are naturally formed.
The pollution environment is also the second environment (the environment of human cause):Refers to the transformation caused by human production activities and social life to the natural environment, which has caused its original component characteristics and structural characteristics to change violent and even quality, forming a new environment that is not completely synchronized with the original natural environment.
2. Environmental elements

3. Environmental quality, environmental capacity and environmental effects
1) Environmental quality
Refers to the appropriateness of some elements of the environment or generally to the development of human or socio -economic development in a specific environment.
Environmental capacity
Refers to human survival and natural environment without being harmed, the environment may accommodate the maximum load of pollution substances.
2) Environmental effect
Refers to the phenomenon and consequences of the environment under the action of environmental elements.
3) Environmental characteristics
a) Platerality; B) Limitation; c) Irregularity; d) hidden nature; e) continuity; f) Disaster amplification.
