[Comprehensive evaluation of carcinogenic load of development areas in Orenburg].
The paper identifies a risk for cancer for the population of Orenburg. Different environmental objects were found to contain 27 carcinogens. The highest proportion of priority carcinogens was recorded in drinking water, the least one was in the snow cover. There was a significant direct correlation between the pollution of soil and that of the ambient air, as well as water and deposited media.

[Hazard identification and comprehensive evaluation of allergy load on the population of an industrial town].
The paper presents the results of qualitative and quantitative analyses of air allergenic chemical pollution of the environment of development lands of Orenburg. The pollutants forming an allergic load are identified. ⋯ The Industrial District of the city was ascertained to be a highest-risk area. The greatest allergenic load has been recorded in winter months.

[Estimating the hazard of toxic exposure of the population living in the area of the Orenburg gas-chemical complex to specific pollutants].
Health anomalies in children are induced by environmental contamination with pollutants specific for this region due to the long-term running of the Orenburg gas-chemical complex. On assessing the health hazard of exposure to non-carcinogenic chemicals, the authors used such variable as the hazard coefficient. ⋯ According to the data of route studies, the hazard coefficient exceeded 1 with reference to hydrogen sulfide and nitrogen dioxide. Thus, upon exposure to specific air pollutants, such hydrogen sulfide and nitrogen dioxide, even at the concentrations below the maximum allowable concentration there is an increased hazard of their toxic effect on the population.

[Hygienic assessment of trace element levels in drinking water and food products within the system of socio-hygienic monitoring system].
The paper provides a comprehensive hygienic assessment of the levels of the essential and toxic trace elements chosen in terms of regional features in drinking water and foodstuffs of locally manufactured products. Priority pollutants of drinking water and foodstuffs are defined in the eastern, western, and central lands of the Orenburg Region. A significant imbalance of essential trace elements was revealed. Daily oral intake of priority and toxic trace elements were calculated in foodstuffs and drinking water.

[New microbiological approach to analyzing the sanitary and ecological status of natural water reservoirs].
The paper shows that in addition to the qualitative characteristics that are of rather informative value for evaluation of the sanitary and ecological conditions of environmental objects, there are suitable qualitative characteristics that may reveal the changes preceding irreversible changes in the natural environment. As such, the factors of persistence which are rather widely prevalent in aquatic microorganisms. By taking into account that the persistent properties of microorganisms label an ecological affiliation of bacteria, ecological type-specific differences of hydrobionts in persistent characteristics, they may be used as informative criteria for an indicator value in sanitary and ecological work. The value of these materials is great in the applied point of view as just now they open up vistas for microbiological monitoring and ecological studies of natural water reservoirs.
