Comparative Study[Sanitary and microbiological evaluation of the hydrosystem in the Volga river estuary upon anthropogenic pollution].
The paper gives many years' data on the size of the opportunistic and sanitary-significant microflora of pike perches (Stizostedion) and water in the producer's food fish areas of the Volga river estuary, as well as the results of ecological and microbiological studies of the water from the above areas, which include the determination of the total amount of the bacterial plankton on membrane filters, the number of heterotrophic bacteria, which has provided an assessment of the habitat quality of hydrocoles in accordance with the complex ecological classification of the quality of the land's surface water. The paper analyzes the seasonal abundance and spatial distribution of the most common opportunistic microorganisms, as well as the markers of their pathogenicity.

[Assessment of a risk from exposure to atmosphere bus industrial emissions].
The carcinogenic and noncarcinogenic risks to health were estimated in accordance with the requirements stated in the guide P 2.1.10.1920-04 "Guidelines for assessing the health risk in the population exposed to the chemicals polluting the environment" (approved by G. G. ⋯ The individual carcinogenic risk to health has been found to be higher than the acceptable (safe) level (10-4) was due to the probable exposure to a 2-heptane fraction (nefras ChS 94/99) and hexavalent chromium. The highest non-carcinogenic risk to human was also due to the heptane fraction (nefras ChS 94/99) (hazard coefficient > 1).

[Evaluation of the sanitary-and-epidemiological hazard of solid garbage in Astana].
According to the national plan of actions on environmental protection, industrial garbage recycling is to be introduced in Almaty and Astana for the sustainable development of the Republic of Kazakhstan. Integrated assessment of the hazard of garage is made by the sanitary-and-chemical and sanitary-and-epidemiological indices to provide the hygienic and ecological reliability of a procedure for neutralization and utilization of solid garbage (SG). According to the data obtained, Astana SG Astana in summer is characterized by the high total level of bacterial contamination. ⋯ Comparison of the sanitary-and-epidemiological indices of different types of SG (wastes from housing facilities, wholesale and retail outlays, and education, culture, and entertainment institutions) revealed no significant differences. According to the sanitary-and-helmintological indices, the Astana soil should be classified as pure (noninvasive). Involvement of SG into industrial recycling should be accompanied by a hygienic assessment of the hazard of waste and the reliability of used technologies in the context of warning and on-going sanitary surveillance.

[Prediction of acute inhalational effects in the assessment of a risk to human health].
The paper deals with a problem in choosing the criteria for a risk of acute inhalational exposures. It analyzes Russian, foreign, and international criteria for ambient air quality, by using the most authoritative sources (Agency of Toxic Compounds and Diseases Registration; Office of Environmental Health Hazard Assessment of US Environmental Protection Agency, etc.). ⋯ The issues of prediction of the regulated indices of evaluation of varying toxic effects on the population's health are considered. Valid models have been developed to predict the reference concentrations upon acute inhalational exposure to chemical substances, which allow the uncertainty in the assessment of the risk caused by acute exposure to ambient air pollutions to be reduced.
