Aim. Generalization of literature and proprietary data on genetic-physiological and evolutionary processes occurring in human populations in environmentally neglected industrial cities. In the review information is given about damage to the genetic apparatus of cells of a human organism under influence of unfavorable environmental factors and disadaptations of different genesis. To denote the totality of alterations induced by the given exposure, a new term is introduced – ‘genetics of disadaptations'. The information of mutagenic factors of the environment of industrial cities associated with growth of oncological diseases and of malformations resulting from chromosomal aberrations in cells is generalized. The problem of genetic burden of human populations in environmentally neglected territories and of the influence of disadaptive factors on this process is discussed. Information of the ecological situation and morbidity of the population in Cherepovets industrial city is given. A role of disadaptations in genetic-evolutionary processes occurring in human populations is shown. The cause of different manifestations of disadaptation in the population is stated to be divergence of traits. A hypothesis is proposed and evidences are given in favor of the existence of natural selection for a disadaptive trait in human populations. It is suggested that being accumulated in a human organism, disadaptive disorders may be transmitted to the next generations reducing vital ability of organisms and inducing different diseases. Conclusion. Within the topic, examples of different prophylactic measures for improving the health of the population of industrial cities are given to prevent unfavorable alterations of human genome under the influence of unfavorable ecological and related disadaptive factors.
