Comparative Study[The dynamics of the risk of morbidity in the industrial cities of Irkutsk region].
An assessment of the dynamics of medical and environmental situation in the industrialized cities of Irkutsk region on the relative risks of morbidity in children and adolescents due to changes in environmental loads in recent years (air pollution levels) was performed. The data presented indicate to environmental troubles in territories of considered industrial cities over the past two decades due to the high degree of intensity of medical and environmental situation on levels of morbidity (accordingly to medical aid appealability rate) of child and adolescent population.

Comparative Study[On prediction the hygienic standards of chemical substances having a selective action, in the atmospheric air of populated areas].
There are proposed new mathematical models for calculation the TSELs of substances with selective (with a predominant effect on the nervous system, liver and specific irritant action) or polytropic character of influence on the organism body in a single inhalation exposure. For substances with a predominant effect on the nervous system and the simultaneous effect on the kidney, liver and nervous system there was established high correlation between the TSELs and Limac.

[Analysis of radiation-hygienic and medical consequences of the Chernobyl accident].
Since the day of "the Chernobyl accident" in 1986 more than 25 years have been past. Radioactively contaminated areas 14 subjects of the Russian Federation with a total area of more than 50 thousand km2, where 1.5 million people now reside were exposed to radioactive contamination. Currently, a system of comprehensive evaluation of radiation doses of the population affected by the "Chernobyl accidents", including 11 guidance documents has been created. ⋯ In 2011 - 20/2 there were carried out comprehensive maritime expeditions under the auspices of the Russian Geographical Society with the participation of relevant ministries and agencies, leading academic institutions in Russia. In 2012, work was carried out on radiation protection of the population from the potential transboundary impact of the accident at the Japanese nuclear power plant Fukushima-l. The results provide a basis for the favorable outlook for the radiation environment in our Far East and the Pacific coast of Russia.

[Justification of the significance of Pseudomonas aeruginosa index in assessing the quality of drinking water].
The analysis of literature data was carried out and performed research justifying the epidemic value of detection in water P. aeruginosa in drinking and domestic water use. The were revealed features of the vital activity of P aeruginosa in water bodies as opposed to conventional microbiological indicators. It was shown that the coliform group indices can not guarantee the epidemic safety of drinking water use in relation to P aeruginosa. The data obtained justify the need for the introduction of P aeruginosa as an additional index in monitoring the water quality of centralized and decentralized water supply.

[Factors of anxiety and autonomic tonus in senior preschool children from Magnitogorsk].
In the paper there are presented the results of a study of anxiety and balance ofparts of autonomous nervous system in healthy children 5-7 years old, residing in different parts of Magnitogorsk. It is shown that state of heightened and high alert was shown to be more common among children living on the left bank of the Urals river around the Magnitogorsk Metallurgical Integrated Plant. In these children an imbalance in the work of the parts of the autonomic nervous system was detected more frequently, at that shifts were observed mainly in the direction to ergotropic tone. ⋯ Discovered psychosomatic features of examined children turned out to be associated with both the social characteristics of family lifestyle and the emotional stress of parents, and the contents of some organic compounds in total snow samples collected in the territories of kindergartens which they attended. One ofthe most significant results ofthe work we consider the detection of a correlation relationship between emotional stress of parents and activity of key enzymes in their children, reflecting the protective and adaptive reactions of the organism. On the basis of these and previously obtained data, we suggest that social and psychological factors of the family are not only a potential source of maladaptation of the child, but, probably, can have an impact on the stability and sensitivity of the genome of children.
