Objective - hygienic characteristic of labor conditions and labor process mobile workers: administrative and office workers and technicians. Office workers are exposed to a combination of factors: climate parameters of electromagnetic radiation of different frequency range, static electricity, etc., and their work is characterized by neuro-emotional stress 3 class first degree.. The main adverse factor for technicians is the electromagnetic field of ultrahigh frequency from the base stations, which is the energy flux density in the workplace in 28% of cases exceeds the permissible parameters. Complex assessment of working conditions made it possible to carry the working conditions of technicians - harmful to the third class 2 and 3 degrees, depending on the intensity of the electromagnetic energy.

The aim of the study was to estimate the prevalence of diabetes mellitus (DM) among children and adults of industrial Levoberezhniy district of Voronezh and to analyze of air pollutants effect on diabetes primary morbidity. It has been found that in children from 0 to 14 years the prevalence of diabetes mellitus is 0.1 - 0.6 cases per 1000 population and is represented by type 1 diabetes. In adult population (18 years and more) the prevalence of diabetes is mainly represented by type 2 diabetes with a frequency of 2 - 5 cases per 1000 population. Type 1 diabetes also occur in some years, but its frequency ranges from 1.2 to 5% of the total number of newly diagnosed DM. Correlation analysis showed the presence of certain regularities between the indicators of diabetes 1 primary morbidity annual average concentration of sulfur dioxide, formaldehyde and carbon monoxide in the atmospheric air. Type 2 DM correlates with annual average concentration of copper oxide. Pair correlation coefficient varies from 0.47 to 0.79. According to medico- social serious consequences of this disease, early detection of carbohydrate metabolism disorders and regenerative therapy of medical rehabilitation is necessary.

The article describes the characteristics of underground aquifers and water quality from artesian wells used for centralized drinking water supply to the population of the Ryazan region. Purpose of the study: To give a comparative description of the quality of water in underground water sources used for centralized household and drinking water supply in the areas of the Ryazan Region. Materials and methods: The material of the study was data on the quality of artesian aquifers in the Ryazan Region. The method of comparative analysis was used. Statistical processing was carried out by the method of variance analysis. Results of the research: Due to the fact that water from different aquifers is used for water supply in the regions of the Ryazan region, it seemed expedient to conduct a comparative study of the chemical composition of artesian waters in some settlements of these territories. Since the Ermeshinsky, Kadomsky and Pitelensky districts use the Podolsk-Myachkovsky aquifer, the Oka-Tarusa aquifer is used in the Mikhailovsky region, and in the Ryazhskoye, Sapozhkovsky, Sarayevsky, Skopinsky and Uholovsky districts the Ozersko-Khovansky aquifer is predominantly used comparison of water quality in these areas. The study revealed statistically significant differences in the average concentrations of iron in the water of underground sources of water supply in Ryazhsk, Sapozhok, Sarai, Skopin, Uholovo, and sulfates in Ermis, Kadom, and Pitelino. The differences in the concentration of iron (2+) can be explained by the use in the city of Skopin of the waters of the Ozersko-Khovanskii aquifer characterized by its higher content. A higher content of ammonium salts in the water of artesian wells was characterized by the Oka-Tarusa aquifer, which is located in the Ryazan Region in the Mikhailovsky District. The high content of ammonium salts in the artesian wells of the Mikhailovsky district can be related to the fact that the average depth of artesian wells in the Mikhailovsky area is on average 26 to 50 meters, which in turn can indicate the arrival of organic substances from the surface. Conclusions: Various aquifers are used in the territory of the Ryazan region. In the Ermeshinsky, Kadom and Piteleni districts, the Podolsk-Myachkovskiy aquifer is used, in the Mikhailovsky region the Oka-Tarusa aquifer is used, and in the Ryazhskoye, Sapozhkovsky, Sarayevsky, Skopinsky and Uholovsky districts, the Ozersko-Khovansky aquifer is predominantly used. In Skopin, the concentration of iron in the wells reaches 1.38 mg / l, which in accordance with GOST 2761-84 "Sources of centralized domestic drinking water supply. Hygienic, technical requirements and selection rules "indicates that this source of water supply can be attributed to the second class. The higher content of sulfates in the water in the territory of Kadomsky district can be associated with the use of the Podolsk-Myachkovsky horizon. The increased content of ammonium salts in the city of Mikhailov is associated with the use of the Oka-Tarusa horizon, which lies at shallow depths, which in turn causes a large number of wells with a depth of up to 25 meters, and this can lead to potential organic contamination from the surface.
