[Specific features of the development of pathology of the upper respiratory tracts in the workers employed in the ore mining industry in the subarctic regions].

Criteria for the risk of development of occupational pathology of the upper respiratory tracts in the workers employed in the ore mining industry have been proposed based on the results of evaluation of the occurrence of pathological changes, morpho-functional characteristics of upper respiratory tract mucosa, and immunological properties. These criteria provide a basis for the development of differential approach to the choice of priority hygienic and medical preventive measures designed to a lower the risk of respiratory organ pathology.
