[Heterogeneity of microbial communities of surface waters on indices of antibiotic resistance of bacteria].
Microorganisms isolated from reservoirs within urbanized areas, have acquired multiple antibiotic resistance, in this connection during the microbiological monitoring of water objects as an additional criterion of anthropogenic pollution it is worth to take into account indices of antibiotic resistance of bacteria. The study of heterogeneity of microbial communities of largest reservoirs in Eastern Siberia (Angara River and Lena) in terms of antibiotic resistance bacteria was performed from the positions of cluster structuredness. ⋯ Thus, the heterogeneity of the microbial populations permits to present comparative quantitative assessment of reservoirs, as well as their portions, in terms of antibiotic resistance of microorganisms. The increment in the proportion of resistant strains reflects the sanitary and epidemiological importance of this property, because provides evidence of the contamination of water supplies by household sewage.

[New methodological approach to hygienic audit of learning and upbringing environment for children in educational institutions].
A methodical approach to the hygienic assessment of the educational environment in children's educational institutions was developed and tested for the objective determination of the level ofsanitary and epidemiological welfare and effective planning of preventive measures with bearing in mind environmental factors which have the most negative impact on children's health.

[Assessment of risk of contamination of drinking water for the health of children in the Tula region].
The hygienic analysis of centralized drinking water supply in Tula region was performed. Priority contaminants of drinking water were established. On the base of the application of risk assessment methodology there was calculated carcinogenic risk for children's health. A direct relationship between certain classes of diseases and pollution of drinking water with chemical contaminants has been determined.

[The features of the establishment of zones of sanitary protection of the water source].
There are regulatory gaps in sanitary laws, which specify the procedure of approval of projects of sanitary protection zones (SPZ) of water objects. It goes without saying that natural complexes, where water intake is organized, should have a special ecological status, which plays a substantial role in the creation of favorable conditions for human health. ⋯ Sanitary regulations and standards (SanPin) 2.1.4.1110-02 as well as the Water Code of the Russian Federation do not fully take into account the statements of some Federal laws regarding the protection of water objects. E.g. according to the Federal law No 33- FL of 14.03.1995 "On specially protected natural reservations" there is a legal base for increasing the status of SPZ of water sources by enlarging the list of Specially Protected Natural Reservations by including SPZ therein.

[Assessment of the quality of drinking water in the industrial city and risk for public health].
Karabash city sprang up around the copper plant that uses local copper ore, which was composed of zinc, sulfur, barium, beryllium, arsenic, manganese, lead, antimony, chromium, cadmium, gallium, indium, scandium, thallium, germanium, osmium, and others. Centralized water supply for the city is organized from the lake Serebry and the flowage on the river B. Kialim. ⋯ Carcinogenic risk is caused by arsenic compounds, hexavalent chromium, and dichloroethane. Carcinogenic risk from water sources of decentralized water supply is 9,6 E-05, for water from Kialim reservoir--7,3 E-05. Maximum carcinogenic risk is associated with the water from the Serebry aqueduct, the risk reaches 2,17 E-04 and is characterized as unacceptable.
