Comparative Study[Regional features of children's biological reactions to environmental factors].
The levels of trace elements in the biological substrates were comparatively analyzed in the children living in the towns of Aktobe, Orenburg, and Orsk. The values of blood metals were ascertained in the Aktobe children residing in the areas differently spaced from the town's industrial zone. Immunity was evaluated and the degree of immunodeficiency was established.

Comparative Study[Comparative hygienic evaluation of the interenvironmental distribution of trace elements in the environment].
The paper presents the results of long-term monitoring of the content and interenvironmental distribution of the chemical elements Ni, Cd, Pb, Cr, Cu, Zn, Fe, and Mn over 1993-2007 in the environmental objects. The studies were made in the urbanized and rural areas of the Orenburg and Orsk-Troitsk industrial centers. General regularities were found in the quantitative distribution and priority relationships of the elements in the drinking water, in the atmosphere of residential areas (snow cover), in soil, foodstuffs, and children's biomedia.

Comparative Study[Influence of environmental factors on the pediatric population in the urbanized and rural areas of the Orenburg Region].
The paper gives the data of studies establishing the regularities of formation of the composition, levels, and space-time features of pollution of ambient air, soil, and drinking water in the risk of their influence of the health status of the children residing in the urbanized and rural areas. The studies have ascertained that the magnitude of a complex anthropogenic load of the environment on the pediatric population living in the urbanized area is 4.9 times higher than that in the rural area. ⋯ The urbanized area has been found to be most unfavorable as to the risk of development of non-carcinogenic effects with the calculated hazard indices being kept in mind. The same trend is shown for the calculated population risk indices.

Comparative Study[The functional status of the autonomic nervous system in schoolchildren and gymnasia pupils upon complex exposure to schooling and environmental factors].
The paper gives the data of a study evaluating the autonomic nervous system in 645 gymnasia and school pupils exposed to different anthropogenic loads of K(total) 25.81 and 22.74 units and to the complex influence of intraschooling environmental factors of a gymnasia and a school. The studies have established that multicomponent influence of poor factors of the educational space and the environment is much more responsible for the functional status of the autonomic nervous system of gymnasia pupils than that of schoolchildren, which leads to disorganization of intra- and intersystemic effector interactions and appears as excess autonomic provision.

[Hygienic evaluation of soil pollution in a South Ural agroindustrial region].
The results of soil monitoring the Orenburg Region (from 2003 to 2007) were comparatively analyzed. The structure of soil pollution with gross (vanadium, lead, nickel, chromium, cobalt, manganese, copper, zinc, tin, titanium, boron, molybdenum) and mobile (cobalt, manganese, copper, zinc, chromium, nickel) compounds was revealed. The Orenburg Region's soils experience an anthropogenic load, as evidenced by a two-fold soil clarke excess as described by A. ⋯ The highest soil pollution has been established in the eastern region that is most industrially developed. The presumable associations with possible pollution sources are outlined. Correlation analysis has revealed the inter-environmental distribution of trace elements in foodstuffs and the population's biological media.
