Biophysical aspects of the effect of physical and chemical factors on living organisms. Protective properties of antioxidants

: The review deals with the biophysical changes of free radical nature, which occur in living organisms under the action of environmental physical and chemical factors, i. e. ionizing irradiation, light, thermal agents, noise, toxic chemical substances. The significance of modern physical and chemical techniques (EPR, NMR, electronic microscopy etc.) in environment monitoring system is considered. A great attention is given to the efficiency of natural and synthetic antioxidants--inhibitors of free radical processes in prevention and elimination of damages in organisms which occur under the action of the factors mentioned above.
