Kharlamova A. Influence of atmospheric pollution by mining and metallurgical enterprises on the formation of psycho-physiological status of 3-7 years aged children

The informative indices of physical, psycho-physiological development in 3-7 years aged children which are sensitive to anthropogenic pollution by mining and metallurgical enterprises are highlighted in the dissertation. The unfavorable effect of atmospheric pollution in mining and metallurgical region on parameters of embryonic and postnatal development is experimentally proved. It is found that the action of aerogenic xenobiotics on fetus during embryogenesis leads to changes in the functioning of central nervous system, reducing the functional reserves of the cardiovascular and respiratory systems of animals in different postnatal life periods, indicating the reduction of animal organism's adaptation to environmental conditions. It is determined that sensitivity of hemodynamic parameters to the unfavorable environment differs in children of different age and sex groups and the negative effects of environmental exposure on the cardiovascular system increase with age, while in 6-7 aged girls it is more manifested then in boys. It is revealed that informative psycho-physiological parameters (image-logical and visual-active thinking, perception, memory, speech) get worsened in children from 3 to 7 years aged under the influence of anthropogenic factors of mining-metallurgical pro-duction. Under the environmental stress the speaking is sensitive cognitive indicator in 3-years boys, in 6-7 years boys - figuratively and logical thinking, perception; in 3-years girls it is respectively memory and image-logical thinking, in 4-years girls - visual-active thinking, in 5 and 6-years - image-logical thinking.
