Comparative Study[Comparative characteristics of lead and cadmium intoxication in the Khanty-Mansi autonomous district].
The Khanty-Mansi Autonomous District (KMAD) occupies a prominent place in the economy of Russia in oil and gas production and energy generation. The development of hydrocarbon raw material extraction in the district does great damage to the environment and nature. ⋯ The levels of lead, cadmium, calcium, and zinc were measured in the hair of indigenous and non-indigenous populations of the district. High lead and cadmium and low calcium and zinc concentration were found in indigenous adults and children in the KMAD.

Comparative Study[Regional standardization of water chemical substances in case of the Arkhangelsk region].
The paper gives the data characterizing the status of water supply systems, the efficiency of waterworks, and the quality of drinking and Severnaya Dvina River waters. It generalizes the data characterizing the sanitary-and-epidemiological situation and human health in the region. There is evidence for the assumption that regional standardization of chemical compounds in the drinking water of northern regions should be carried out during water preparation, which confirms the conclusions of hygienic and toxic studies previously conducted in individual areas and those given in the references.

Comparative Study[Conceptual model for assessment and management of human risk from transport pollution].
The existing methodology for human health risk assessment allows one to appreciably study cause-and-effect relationships between environmental factors and human health. Risk management is a logic continuation of the assessment of human health risk and it is aimed at substantiating the choice of decisions that are best in a specific situation to eliminate or minimize it, to make follow-up monitoring of exposures and a risk, to evaluate the efficiency of health-improving measures and to correct the latter. Risk management involves technical, technological, organizational, social, legal, economic, normative, political, and other decisions made on the conclusions and estimates obtained when characterizing the risk.

Comparative Study[The hygienic features of nutrition and elemental status in the children of the Orenburg region].
The paper analyzes the trace element status in the children residing in Orenburg and the Sakmarsky District, Orenburg Region. The study was conducted among 2nd-3rd-form pupils. Their hair samples were used as a biosubstrate to ascertain the trace element status; chemical elements were determined in accordance with guidelines 4.1.1482-03 and 4.1.1483-03 approved by the Ministry of Health of the Russian Federation in 2003. The studies ascertained the children's trace element profiles that are indicative of the high prevalence of imbalance in the hair content of elements among the rural children in the presence of inadequate nutrition in both rural and urban schoolchildren.

Comparative Study[Monitoring of biological contamination of household water supply objects].
Biological contamination of environmental objects was monitored in 245 monitoring points of the region according to the monitoring observation program. In 2005-2008, the proportion of drinking water samples from the distributing network of household water supply systems, which meet no hygienic standards, is 1.3 to 1.8% and the proportion of those from non-centralized water supply sources is 6.2%, which is due to a weak protectability of aquifers from their surface contamination. Comprehensive assessment of household water supply factors has indicated that water preparation and transportation are key links in the formation of household water supply problems.
