It should be added that not only the large number of indicators and aspects that require research, but their registration can occur in different ways. Finally, the information gathered may have a professional?nonaucnuu focus: economic, social, legal, geographic, etc.
There are difficulties in determining maximum permissible emission (MPE) of pollutants, so that they do not exceed the maximum allowable concentrations (MACs). Because the same depending on environmental emissions, in particular climatic conditions can lead to a variety of concentrations and vice versa, the task of calculating VAT for this source of pollution, generally speaking, in each case unique.
In the literature often use the term "environmental damage" and is associated with negative effects of Technogenesis. It usually refers to the actual or possible loss arising from adverse changes in the natural environment due to human influence.
