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.

Review[The chemical and trace element composition of water sources in the Orenburg Region].
The chemical composition of drinking water was studied by some indices: total mineralization, oxidability, harshness by different regional economic areas of an angoindustrial region. The content of trace elements, imbalance of which had been found by earlier studies, was determined. Higher water mineralization was ascertained in the central area, higher water harshness and oxidability were in the eastern area. The areas under study showed the inhomogeneous content of trace elements.

Comparative Study[Practical use of a methodology for assessing an aerogenic risk to human risk in the substantiation of a control area].
The aerogenic risk to health was assessed in the population living in an area under the influence of an petroleum refinery in order to define the ambient pollution hazard, to identify the leading risk factors and their sources for further development of the most effective managerial decisions to reduce the risk, which comprise the substantiation of the extent of a control area.

Comparative Study[Malignancy monitoring in the pediatric population of the Orenburg Region].
The paper gives the results of a retrospective epidemiological survey for malignances in the pediatric population of the Orenburg Region in 1995 to 2007. The average long-term morbidity rates were determined by the main (central, western, eastern) areas of the region; the areas were ranked by the malignancy morbidity rates among the pediatric population as a whole and by nosological entities. The authors provide the structural characteristics of cancer in the Orenburg Region as compared with the general Russian data.

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.
