[Influence of some environmental factors in urban areas on public health (review of literature)].

The authors present results of studies concerning influence of environmental factors in urban areas on public health. Modern men indoors and outdoors are exposed simultaneously to multiple hazards with levels sometimes exceeding physiologic tolerance, and some of these hazards could be assigned to risk factors. Preventive medicine requires new theoretic basis for prophylactic activities grounded on medical ecologic and biologic views explaining cause-effect relationships between mechanisms of human health in connection with environmental hazards.
