ASSESSMENT OF ENVIRONMENTAL RISKS OF THE POPULATION HEALTH IN AREAS RANKED BY THE DEGREE OF TECHNOGENIC POLLUTION

Abstract

The aim of this article is identification of environmental risks to the public health from polluted areas. Methods. Ranking of all districts of the Bryansk region according to the degree of radiation-chemical pollution of environment (E) for 8 environmental groups was made to analyze cause-and-effect relationships in the system "environmental factors - health status of the population", according to the environmental condition of the region and annual statistical reporting. Ecological groups were used to study the dependence of hematological parameters in patients with allergopathology from the degree of the territories contamination. To estimate the impact of E factors on the health status of the population the analysis of variance (fixed effects model) and a nonparametric analysis of variance using non-parametric rank criterion of Kruskal and Wallis was applied. 403 adolescents aged 15-17 years were examined. Functional indicators of the cardiovascular system with the calculation of the adaptive capacity of circulation, the content of immunoglobulin classes M, G and A were studied. /4s a result a statistically significant sensitivity of eosinophilic (Fcalc = 3,46 at Fbl = 3,05) and platelet reactions (Fcalc = 6,19 at Ftabl = 3,05) to the degree of technogenic pollution of E was established. Statistically significant sensitivity of the hemoglobin, leucocytes and thrombocytes was stated (Ncalc = 9,68; 9,83 and 9,48 at Ntabl = 9,49) to the degree of environmental technogenic pollution. Conclusions. The factor analysis affecting the surveyed organisms discovered the role of increased technogenic loads, each of radiation and chemical nature as health risk. Students living in conditions of combined radiation-chemical and radiation pollution of the E, discovered increased levels of immunoglobulin classes M, G and A. The analysis allowed to identify early signs of eco-dependent pathology risks with the aim to work out measures for the prevention of such diseases development.
