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).

Comparative Study[Complex effect of lead on various routes of human entrance in the Far North].
The results of the performed comprehensive study have allowed the authors to give a hygienic assessment of the risk from environmental lead pollution in the Yamal-Nenetsk Autonomous District. By taking into account the regional features in their studies, the authors revealed certain regularities in the formation of environmental lead pollution where, along with a tendency for ambient air pollution to rise, there was a conjugated impact on the quality of portable water on the increase of a complex environmental load. ⋯ To minimize the risk of environmental lead pollution to human health, the regional lead standards has been scientifically founded and recommended for the inhabited localities of the Yamal region, by keeping in mind its combined impact on the organism. When all environmental objects are polluted, human health safety may be, on lead's coming into the body via various routes and modes, afforded if the level of the metal in ambient air of 0.0002 mg/m3 and with that in the drinking water of 0.01 mg/l.

Comparative Study[Assessment of a risk from environmental factors to human health].
Analysis of the findings has shown that the estimation of the sensitization requires the use of a battery of tests, by taking into consideration both the persons having positive tests and the number of positive tests of the used ones. It is necessary to note that the estimation of the specific sensitization to hexavalent chromium has indicated the higher levels of parameters and percent of positive tests among the children living in the area adjacent to the industrial zone with a further decrease as the major sources of pollution is farther. It should be noted that the chromium sensitization is 10% even in the most distant areas.
