Omprehensive Ecological-Hygienic Evaluation of Environmental Objects of the Territory Under Harmful Climatic and Anthropogenic Exposure

Abstract

Adverse climatic and anthropogenic factors can affect the health of people living near the dried-up Aral Sea. There was modified the comprehensive assessment of inorganic chemical pollution of the environment of the village in the Zhosaly Kyzylorda region of Kazakhstan. The comprehensive assessment score included 5 categories: satisfactory, intense, critical, crisis, catastrophic. According to own research over 2014-2015 based on the mentioned assessment score, the comprehensive assessment score amounted to 41 points and showed a critical situation. In the air, there was observed the phenol content of 1.02 MAC, suspended solids - 0.5 MAC. The main part of the fine suspended solids sized of 1.5-2.5 mm, round shape, was formed in the process of condensation and evaporation of the sea and the Syr Darya River. In the dust, there was found the excess in silicon content of 2.8 MAC, iron - 1.3 MAC, zinc 1.1 MAC. As soil pollutants, there were detected sulfates - of 173.5 MAC, chlorides - 9.0 MAC, mercury - 0.56 MAC, nickel - 0.49 MAC. In drinking water, there was revealed cadmium excess of 1.3 MAC, nickel - 1.2 MAC, chlorides - 1.25 MPC, sulfates - 1.0 MAC. In the water of the Syr Darya River, there was revealed an excess in nickel - of 2.2 MAC, sulfates - 1.8 MAC, dissolved oxygen - 2.0 MAC. In the sediments of the Syr Darya river, the sulfate content accounted for 3.36 MAC and chlorides - 1.53 MAC. In the snow cover there was revealed an excess of manganese - 5.14MPC, chromium - 2.04 MAC, zinc - 1.2 MAC. In a critical situation a significant portion (30-50%) of the population may be in a state of exertion and adaptation surge, and the most susceptible part seems to be in a state of adaptation failure, characterized by an increase in incidence rate.
