Abstract
Currently, serious problems associated with environmental pollution are observed all over the world, especially in developing countries, which manifests itself in the form of a negative impact of environmental factors on the health of the population as a whole, especially on the health of the younger generation. Epidemiological studies conducted in Organisation for Economic Co-operation and Development countries have established indisputable evidence that there is a reliable link between environmental pollution and morbidity and mortality from neoplasms and respiratory diseases. At the same time, there is no reliable data on the role of environmental factors in the development of chronic diseases in children and adolescents, including the study of the interaction between chemical, social, behavioral factors and the gene pool with the environment. That is, these studies had some limitations in studying the epidemiology of chronic diseases and environmental stress factors.
