[The structure of environmental risk factors to the population's health in the Kolsky North].
The paper considers the problem in the comparative assessment of a carcinogenic risk and harm from ionizing irradiation and some chemical ambient air pollutants (formaldehyde, suspended matter) to the population's health in the Kolsky peninsula. The findings suggest that a chemical risk factor has a much greater impact on human health than a radiation risk factor, which should be taken into account while developing a nature-conservation policy in the region.

[Physical factors of the industrial environment and traffic safety].
The paper deals with the problem of optimization of working conditions of engine drivers in the control cabs of up-to-date locomotives, by toughening the sanitary-and-hygienic requirements for the levels of bad industrial factors. The authors associate the optimization of working conditions with the necessity of strengthening the reliability of their driving activity due to the increasing rail movement speeds and the transfer to one-person rolling-stock operation, and other factors.

The paper considers the problem while studying various physical factors of the environment. It presents prospects for further investigations of the influence of physical factors on human health and the quality of the environment. The paper also gives a detailed description of advances and promising lines of studies in the area under discussion.

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.
