[The effect of the factors of the working and living environment on oxidative/antioxidative balance (a review)].

Because of the high reactivity of the free oxygen radicals the maintaining of a certain balance between the activity of the antioxidative system and the level of the free radicals is of great importance for the health of man. Literary data are reviewed concerning the shifting of this balance towards oxidants' excess due to many factors like ionizing radiation, hyperoxia, toxic noxae, considerable physical overstrain, overcooling, stress and others. The antioxidative and pro-oxidative food composition is of special importance for maintaining of the oxidative/antioxidative balance of the organism. The nutrition regiment could mould the toxicity of some of the mentioned agents.
