Review[Topical problems of the comprehensive hygienic characterization of urban environmental factors and their influence on the population's health].
The authors consider the topical problems of the influence of urban environmental factors (the quality of drinking water, the pollution of the ambient and dwelling airs and soil) on the health of residents in the urbanized areas. They show it necessary to apply a comprehensive approach to studying and analyzing the influence of a large number of interrelated factors on the population's health and its vulnerable subgroups, by employing the current sensitive biomedical studies, as well as to develop and introduce noninvasive techniques for the early diagnosis of environment-induced diseases.

[Use of morphofunctional and cytogenetic studies to analyze the influence of environmental factors].
Long-term studies of 2 (cytohistology and genetic monitoring) laboratories of the Research Institute of Human Ecology and Environmental Hygiene, Russian Academy of Medical Sciences, to investigate the influence of environmental factors in the experiments made it possible to develop a noninvasive procedure for evaluating their cytological and cytogenetic impacts on man. A concurrent study of morphofunctional (histological, cytological) and cytogenetic parameters in both experimental and field trials can substantially extend and refine the interpretation of responses to environmental factors, which generates a need for using these parameters in hygienic and epidemiological studies.

A questionnaire survey made in different Voronezh population groups suggests that they spend 80 to 90% of time in the enclosed space. The greatest contribution to the chemical load caused by ambient air pollution made by production areas (54.9%) in the adult able-bodied population and by dwelling areas (56.0-86.9%) in children, adolescents, and pensioners. Pollution of ambient air (K = 9.19) is pronounced to a lesser degree than that of the air of office buildings (K = 12.49), which suggests that there are internal contamination sources in the closed space. The results of the questionnaire survey of respondents suggest that 20% suffer from allergic diseases and 7% of them associate these diseases with dwelling area contamination.
