[Hygienic bases for listing the indicators for evaluation and control of the safety of drinking water].
The authors describe their developed methodology to draw up lists for drinking water quality control on the whole territory of the Russian Federation and at specific waterworks of its subjects. The paper considers a 4-step scheme for applying the methodology and a possibility of its use to add and shorten the lists, by keeping in mind the local sanitary situation. The proposed scheme for listing the priority substances and indicators may be regarded as the optimal solution for equalization of mutually exclusive trends in the quality control of drinking water by a sanitary service and water canals and ensures its safety to human health, reasonably focusing attention only on the minimum of actually priority substances that are individual to each water supply system.

Comparative Study[Comparative assessment of educational conditions in various secondary educational institutions in Samara].
The educational medium in varying secondary educational establishments of Samara was comparatively analyzed in accordance with the sanitary regulations SanPiN 2.4.2.1178-02 "Hygienic requirements for teaching conditions in general educational establishments". The study demonstrated that the teaching conditions at schools primarily required that school load be rationalized and the ergonomic parameters offurniture and artificial illumination improved.

Comparative Study Historical Article[Consideration of a potential death risk in the methodology of assessing the population's health].
It has been shown that when calculating the summarized population's health index and the significance (weight) of partial signs, it is expedient to use the calculation from the potential death risk index rather than an expert judgment. The results of calculation examples using morbidity and mortality rates suggest that public health can be assessed on this methodic ground. It is advisable to apply the proposed method for assessing the population's health during sanitary-and-epidemiological surveillance (sociohygienic monitoring) when decisions are taken on the lines of health-promotion measures to reduce morbidity and mortality mainly by circulatory diseases, neoplasms, injuries, and intoxications.

Comparative Study[Estimation of adaptive capacities in Magnitogorsk children from the activity of some detoxification enzymes].
The paper provides the first fragment of a multiparameter study analyzing the influence of environmental pollution, the social and psychological features of a family, and some endogenous factors on genome stability and sensitivity in a developed ferrous metallurgy town. It also gives data on the urine and serum activity of the lysosomal enzyme N-acetyl-b-D-glucosaminidase (NAG) and the serum activity of catalase in an organized contingent of apparently healthy children (n = 178; 6 kindergartens) aged 5-7 years, who live permanently in Magnitogorsk at different distances from the metallurgical works. More than 70% of children selected for examination were found to have average normal levels of activity of the enzymes studied. ⋯ In the children from the left-bank area, enzyme activities varied more greatly, which suggests the higher prevalence of tense adaptation. Correlation analysis revealed association between the children's serum activity of enzymes and some components of snow pollution. It is anticipated that the found changes in serum activities of N-acetyl-beta-D-glucosaminidase and catalase may be determined by individual differences in a child's response to ambient air pollutants.
