[The impact of environmental air pollution and incidence of acute respiratory viral infections].
The paper characterizes diffuse ambient air pollution (P index) in accordance with the data of Kazan stationary stations in 1996-2000. The incidence of childhood respiratory diseases is studied for the same period. ⋯ There is a direct significance correlation between Kazan's ambient air pollution and morbidity rates in children aged 0-14 years, which is as follows rxy +/- m = 0.626 +/- 0.104. The regression coefficient has been established, which is Ry/x = 0.183 when the atmospheric contamination is changed by one unit.

[Design of medical facilities for the saving of persons exposed to low temperatures].
The paper describes medical facilities for saving victims of general cooling. Physiological ways of recovery of the thermal status of individuals exposed to general cooling are substantiated. A physiological rationale is presented for the design of engineering aids to prevent overcooling in persons who do their work in cold. The specifications of electric heating cloth used in the design of these medical rescue facilities are characterized.

[Development of pre-neurotic disorders in senior school students: hygienic aspects].
The prevalence of preneurotic abnormalies was studied in senior schoolboys from 4 Bryansk regional areas with different levels of radiation contamination. The study is aimed at elucidating the correlation between the rate of development of preneurotic abnormalities and the level of radiation load in the environment. ⋯ There has been no significant relationship of studied psychological parameters to the radiation contamination of an area where the pupils live; however, there is a tendency for deviation from the optimum level of anxiety in senior schoolchildren who reside in radioactively polluted area. While implementing a package of preventive measures, it is necessary to pay a particular attention to the psychological atmosphere in the family of pupils and to the pattern of their learning load.

[Hygienic regulation of environmental air pollution with consideration of epidemiological data].
The authors hold that the maximum allowable concentrations (MAC) established in Russia for some ambient air pollutants can adversely affect human health and that they are worthy of reconsideration. This opinion is based on the published results of epidemiological studies of Western investigators and on the authors' own data obtained from the analysis by the time series method for a relationship of daily variations of dust or gaseous ambient air pollution to the so-called acute mortality or for that of the variations to respiratory symptoms and to the values of the maximum expiratory flow rate in preschool with or without respiratory abnormalities in their history; from the cross analysis of an association of the characteristics of atmospheric contamination in 13 urban areas with the prevalence of chronic respiratory diseases in junior schoolchildren, which was established by a special questionnaire. Particular emphasis should be laid on the reconsideration of not only established values, but mainly on the principles in laying down MAC for dust particles. The Western practice in measuring and evaluating risks separately for fractions of particles of varying sizes should be assessed for its use in Russian conditions; however, the authors' experience argues for this practice.
