Comparative Study[Human health risk assessment of environmental pollution at the municipal level].
The established tense environmental situation in Krasnouralsk, Sverdlovsk Region, presents a serious threat to human health. Development of a medium-term municipal environmental program for a Krasnouralsk urban district provides solutions of environmental problems. The human health status and carcinogenic and non-carcinogenic risks from exposure to chemical substances polluting ambient air, drinking water, and soil have been assessed within the framework of the program. The findings have served as a basis for elaborating technological and sanitary-and-hygienic measures of the environmental program to assure human environmental safety.

Comparative Study[Health status hygienic assessment of primary military education establishment pupils].
During a comprehensive study, the investigators have made a hygienic assessment of an academic process and the actual nutrition of military school pupils, revealed the specific features of functioning of the body's major systems in adolescents at a closed primary military education establishment, studied the body's adaptive reactions to a combination of factors during study, and hygienically evaluated the pupils' health. Their health has been shown to improve at a closed education establishment according to the basic parameters of the body's functional status and nonspecific resistance, physical development. Specific recommendations are proposed to correct daily diets for pupils of primary military education establishments in order to bring the actual nutrition of cadets in compliance with the standard physiological requirements for this group of pupils.

Comparative Study[The cytogenetic status of children living in the vicinity of a pulp-and-paper mill].
To evaluate the cytogenetic and cytotoxic effects of a set of pollutions in the town of Koryazhma, the investigators made a complete karyological analysis (cytogenetic, apoptotic, and indirect proliferation parameters) of buccal and nasal epithelial exfoliative cells in two groups of old school age children living at various distances from a pulp-and-paper mill (PPM). The residential area that is adjacent to the PPM can be considered to be poor in the influence of genotoxic factors since there were 1.6- and 1.65-fold increases in cytogenetic disorders and cells with an atypically shaped nucleus, respectively, with a 1.57-fold reduction in the level of cell apoptosis. Karyological changes were revealed in the nasal mucosa, rather than in the buccal mucosa, which permitted one to recommend for the evaluation of the influence of environmental factors, the impact of ambient air pollution in particular, and to conduct cytogenetic studies on the cells of not only the buccal epithelium (that has been better studied), but also those of the nasal epithelium.

Comparative Study[Rationale for a differential approach to molding a healthy lifestyle in schoolchildren].
The lifestyle of schoolchildren in a large industrial town was studied in relation to the residence (industrial and administrative areas) and the type of an education establishment (general education schools and innovative education establishments). The spread of lifestyle defects (sleep and walk irregularities, inactivity, bad habits, employment) was shown to be higher in the schoolchildren living in the industrial areas, in general education school pupils in particular. That of lifestyle defects was higher in girls (sleep and diet irregularities, inactivity) than in boys. The findings provide evidence that there is a need for a differential approach to molding a healthy lifestyle in schoolchildren, by keeping in mind the environmental and socioeconomic situation of a residence, the type of an education establishment, age, and gender.

Comparative Study[Hygienic rationale for the maximum allowable concentration of agidol 10 in the ambient air of inhabited localities].
The subjects of studies were laboratory animals (rabbits, guinea pigs, albino rats, albino mice) and a chemical substance (agidol 10, a alkyl phenol derivative). The purpose of the study was to provide a rationale for the maximum allowable concentration (MAC) of agidol 10 in the atmosphere of inhabited localities. ⋯ The recommended average daily MAC of agidol 10 was 1.0 mg/mn; the maximum single dose was 2.0 mg/m3. The limiting index was its resorptive activity.
