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.

Review[Assessment of the contribution of environmental factors to the formation of the demographic situation at the regional level].
The most informative priority environmental, social, and economic factors reflecting with the highest significance demographic processes in the urbanized and rural areas have been substantiated from the results of analyzing the data of the Regional Information Fund of sociohygienic monitoring by multivariate (correlation, factor, and regression) analysis methods. Models were obtained, which were used to define quantitative correlations between the demographic indices and the environmental-socioeconomic ones and to identify priority criteria for urbanized and rural areas while predicting their development and taking a managerial decision.

Review[Methodology for integrated assessment of anthropogenic and socioeconomic factors in the formation of a human health risk].
In the context of modern preventive medicine and a diversity of criteria for assessing the health status and the quality of the environment, the author has used an algorithm of comprehensive studies, which includes a differential analysis of the quality of the environment, by identifying xenobiotics in the atmosphere, soil, drinking water, and foodstuffs, then by ranging environmental factors in each specific region, by making a pooled assessment of a risk, by calculating the integral indices of public and community health, and by taking into account the socioeconomic situation in an area. Six priority indices of the 35 environmental ones, as well as 8 socioeconomic conditions that are most closely related with demographic parameters (r > 0.9) have been identified from the summarized environmental and socioeconomic conditions in the urbanized areas. Four ecological indices and 11 socioeconomic conditions have been identified in the rural areas.

Comparative Study[The structure of an aerogenic load and risk to human health in an industrial town's residential area].
Chemical air pollution of the residential and industrial areas of a town was evaluated. There was a significant relationship of the average daily actuating concentrations of priority substances to the air pollution of the study areas, the average annual concentrations of ambient air pollutants to their seasonal values. The structure of the risk to community health and the contribution of the industrial environment to the formation of a health risk were ascertained.

Comparative Study[Human health risk upon air exposure to chemicals in enclosed spaces and residential areas of an industrial town].
The study determined priority chemicals in the ambient air and air of enclosed spaces of the town's administrative districts, by taking into account the formation of a community health risk. The industrial town's areas were ranked by the hazard of carcinogenic and non-carcinogenic effects caused by the varying intraenvironmental distribution of substances. The distribution of pollutants in the study areas with varying anthropogenic exposures allows one to consider suspended matter, cadmium, nickel, and formaldehyde in the air of residential areas and formaldehyde, phenol, and suspended matter in the air of enclosed spaces as universal markers of exposure for dwelling environmental factors in the identification of toxicants and in the assessment of community health risk within the framework of sociohygienic monitoring and as indicators for the assessment of the immediate and final results of purpose-oriented departmental programs.
