The article presents the results of the study of the spread of psycho-emotional disorders in the population living in the Aral region. Pathological abnormalities of the nervous system among the population living in the conditions of ecological disaster are revealed.

Discussed changes occurring under the influence of external factors (РМ₁₀ and РМ_2,5) in the peripheral blood of the population living on the territory of ecological disaster - the Kazakhstan part of the Aral Sea region. We detected changes in erythrocyte parameters, showed the prevalence of these features in the surveyed women. We presented the correlation between particulate matters (РМ₁₀ and РМ_2,5) in the ambient air and blood parameters.

There is presented the hygienic characteristics of the production processes at the enterprise of chemical organic synthesis (production of Acrylonitrile, sodium cyanide and by-products), the analysis of conditions of labor in major industries and the results of the evaluation of their impact on the health status of employees by results of periodic medical examinations. It is shown that in the conditions of regular work of the enterprise and adequate system of hygienic, organizational, technical and medical and preventive measures the risk of diseases associated with working conditions is reduced.

The analysis of the results of quality control and security of their preliminary and periodic medical examinations in the Novosibirsk region in 2015-2017, the most typical violations. Suggested ways to address them.
