[Modern problems of maintenance of hygienic safety of drinking water consumption at the regional level].

Problems of hygienic reliability of the drinking water use in regions of the Russian Federation are observed in the article. The optimization of the water use was shown must be based on the bearing in mind of regional peculiarities of the shaping of water quality of groundwater and surface sources of the water use, taking into account of the effectiveness of regional water protection programs, programs for water treatment, coordination of the activity of economic entities and oversight bodies in the management of water quality on the basis of socio-hygienic monitoring. Regional problems requiring hygienic justification and accounting, include such issues as complex hydrological, hydrogeological, climatic and geographical conditions, pronouncement of the severity of anthropogenic pollution of sources of water supply, natural conditions of the shaping of water quality, efficiency of the water treatment. There is need in the improvement of the problems of the water quality monitoring, including with the use of computer technology, which allows to realize regional hygienic monitoring and spatial-temporal analysis of the water quality, to model the water quality management, to predict conditions of the water use by population in regions taking into account peculiarities of the current health situation. In the article there is shown the practicability of the so-called complex concept of multiple barriers suggesting the combined use of chemical oxidation and physical methods of the preparation of drinking water. It is required the further development of legislation for the protection of water bodies from pollution with the bigging up the status of sanitary protection zones; timely revision of the regulatory framework, establishing sanitary-epidemiological requirements to potable water and drinking water supply. The problem of the provision of the population with safe drinking water requires complex solution within the framework of the implementation of target programs adopted at the Federal and regional levels.

[Risk-oriented model of the control of the level of electric magnetic fields of base stations of cellular communications].

The purpose of this study was to give the description of harmful effects of the impact of electromagnetic radiations from base stations of cellular communication as the most common sources of radio frequencies of electromagnetic fields in the environment. The highest values of the energy flux density were measured on the roofs of houses where antennas are installed - more than 10 pW/cm. The lowest values were recorded in inside premises with expositions of 0.1-1 pW/cm. In the close location of the railway station to the base stations of the cellular communication there was seen a cumulative effect. There are proposed both new safe hygienic approaches to the control for the safety of the work of base station and protective measures.

[The improvement of methodical approaches of hygienic regulation of pesticides in water bodies].

The article highlights the methodical features of hygienic regulation of pesticide preparation in water bodies, concretizes and supplements (specified) number of positions of the acting current methodical document on hygienic evaluation of new pesticides. From the position of the comprehensive hygienic standardization there are marked principles of the study of MPC for pesticides in water bodies, there is substantiated the expediency of expanding the arsenal of methods for determination of threshold concentrations of pesticides on the impact on organoleptic properties of water and sanitary regime of reservoirs, shows the role and importance of hydrolysis processes of active ingredients ofpesticides in water, which should be considered in the assessment of the impact of drugs on the processes of self-purification of water bodies.

[THE HEALTH OF CHILDREN IN THE INDUSTRIALIZED REGION].

There was performed an assessment of the quality of the environment and the state of health of the child population of the one out of industrialized regions of the Moscow region. There were determined priority risk factors for diseases of the respiratory system and skin. The indices and the structure of morbidity rate were analyzed according to the incidence of outpatient visits. There was developed a comprehensive hygienic model for the preventive and therapeutic activities aimed at the improvement of the environment and reduction of the morbidity rate in children's population.

[Safety of nanoparticles and nanomaterials for environmental and occupational space].

National and international experience, international standards, reports and recommendations relating to the assessment of harm to health, safety in the new nanoscale production for environmental and occupational space (ISO / TR 12885:2008 (E), BSI PD 6699-1:2007, etc .) have been analyzed.

[Regional problems in the provision of hygienic reliability of drinking water consumption].

The paper gives the recent results of researches made at the F.F. Erisman Federal Hygiene Research Center on water-supply hygiene. It presents a functional model of comprehensive assessment of the factors determining the sanitary reliability of drinking water supply, shows the specific features of formation of conditions for water consumption in a number of regions of the Russian Federation and the risk of a water factor to human health, and substantiates the mechanism of water quality control and management at the regional level.

[Present-day problems of complex hygienic evaluation of drinking water use].

The authors offer substantiated methodical approaches to complex evaluation of the sanitary reliability of drinking water supply systems. They recommend not only evaluating drinking water quality, but also assessing the sanitary state of water sources (catchment areas), the reliability of water preparation and transportation, the standards of water supply and the reliability of production laboratory control. A range of complex hygienic studies have demonstrated that the problems of Voronezh interurban reservoir as a water source are caused by its multi-purpose use. Under these conditions insufficient hygienic efficiency of the conventional water preparation schemes and low sanitary reliability of water transportation systems favors negative influence of water factor on population mortality. The offered methodical approaches give the systematic idea of factors that determine drinking water quality. Operative administrative decisions concerning hygienic safety of public water use may be made with these methodical approaches taken into consideration.

[Environmental and occupational problems of safe water supply]. / Ekologo-gigienicheskie problemy bezopasnosti pit'evogo vodosnabzheniia.

The paper gives the results of hygienic studies which determine some priorities in formation of unfavourable sanitary conditions of potable water supply in a number of Russian Federation areas. A tendency is shown towards an increase in the content of chemicals with organoleptic and sanitary and toxicological hazards (3-17% rate of increase) in underground and surface water sources, a frequency growth of finding non-standard, by the epidemiological criteria (25%), water test characteristic of areas with intensive industrial and agricultural enterprises. There are risk factors found in the quality of potable water at the stages of water preparation (chlorination) and transportation (corrosion) for human health; data of fundamental studies are given, on hygienic substantiation of ecologically pure methods of water treatment (UV disinfection). Scientific developments have provided the basis for systematizing a number of considerations for basic documents for a law on water protection quality, by revealing and predicting the processes affecting the quality of potable water, improving adequate laboratory water quality monitoring.
