CHEMICAL CONTAMINATION OF THE ENVIRONMENT AND HEALTH STATUS OF PRESCHOOL CHILDREN BASED ON SOCIO-HYGIENIC MONITORING DATA

Abstract

High levels of industrial development of the region’s areas caused long-term and continuous of habitat objects pollution. Based on socio-hygienic monitoring data, over 70 per cent of the Sverdlovsk Region population is exposed to a set of various chemicals, and children constitute the most sensitive risk group. Lead, cadmium and arsenic are priority contaminants of the habitat in industrial cities and towns of the region. According to the integral estimates, chemical contamination of the habitat by these toxicants forms non-carcinogenic risks to public health. The established non-carcinogenic health risks are confirmed by social and hygienic monitoring indicators of the children chronic morbidity level in organized groups and indicate a statistically significant excess compared with the average regional indicators. According to the mathematical modeling data, statistically significant interrelations were found between the content of lead, cadmium, arsenic in environmental objects and the biomonitoring results.
