At present it is a fact that changes in our living environment are much rapid than the progress of the human health protection techniques because we know the organism environment relationships only superficially. The rate of environmental changes, which is now faster during the life of one generation than previously took place during centuries, as well as disturbances in biorhythms, are the most dangerous symptoms of changes in ecological relationships. The environment comprises the overall surroundings of any object. In ecology the environment means all factors which affect the survival and reproduction of living organisms. Elements of the environment are : (a) Building and energy-sdupplying components, and (b) Regulatory components. Thus the environment comprises : material factor whose presence is decisive for survival and development of living organisms (oxygen, carbon, hydrogen), and factors regulating the living processes, e.g., compounds making part of the organism but present in small amounts (including catalysts and inhibitors of metabolic progresses). We hope that this timely publication will give some help to scholars/reasearch scientists to carry their further studies on environment.
