[The epidemiological validation of the MPEL for grain dust in the atmosphere].
The use of calculating and gravimetric methods for examining the grain dust pollution of the ambient air at the site of an elevator determined the maximum single, mean daily, and mean annual concentrations at different distances from the source of dust emission. The mean ratio of these concentrations was 12.1:4.3:1, respectively. The calculated concentration-effect and concentration-time relationships provided evidence for the maximum single, mean daily, and mean annual allowable concentrations for grain dust in the ambient air.

Comparative Study[Prevention of health status impairment in children under conditions of the Extreme North].
Under the influence of climatic and geographic conditions of the Arctic, 7-9-year-old children develop some functional tension, as evidenced by studies of their thermal reactions and cardiorespiratory system. Ethnic thermoregulatory features were found, which involved retained sensations of thermal comfort at lower skin temperatures and a higher gradient of skin temperatures in the trunk and extremities. In the morbidity pattern of young school-children, there is a prevalence of acute and chronic respiratory diseases whose major causes are cooling and recooling. The findings suggest that there is a causality of the children's health status and the environmental factors and show it necessary to develop scientifically substantiated preventive and conditioning measures to promote children's health.

Comparative Study[Social-hygienic aspects of optimization of child nutrition in the Extreme North].
Children's nutrition in the Arctic areas is characterized by deficiencies of major nutrients and some groups of foodstuffs, among which there are lower dietary protein, fat, and vitamin intakes, shortage of meat, fish, dairy products, fresh vegetables and fruits. Based on the studies, the authors propose within the framework of the goal-oriented programme "Children of the North" their complex hygienic recommendations for optimization of nutrition and alimentary status of the Arctic children, involving some functional nutritional elements aimed at improving and promoting their health.
