POSSIBILITIES FOR THE REDUCTION OF THE NEGATIVE IMPACT FROM THE USE OF SECONDARY FUEL FROM SOLID MUNICIPAL WASTE ON SANITARY CONDITIONS OF THE LIFE AND HUMAN HEALTH

Vaisman Y., Korotaev V., Borisov D., Bazyleva Y., Barannikov V.

Аннотация

There are considered possibilities of the reduction of the negative impact of the use of secondary fuels from solid municipal waste (SMW) on the sanitary conditions of the life and health through the application of the proposed technology for production of solid fuel of specified quality with the content of acceptable levels of hazardous components that determine the formation of emissions of priority pollutants under the use of the secondary fuel. There are presented results of investigations for the production of a proposed quality of secondary fuels from SMW with the use of the experimental-industrial complex for the optical and mechanical sorting of the waste. There is described the technology of the production of sanitary, toxicological and environmentally safe recycled fuel, based on the use of methods of optical-mechanic waste sorting and devices allowing to reduce in the secondary fuel, the content of chlorine-, mercury-and cadmium-containing components to the normative level and low-calorie roughage substances. There are given recommendations for the reduction of the anthropogenic impact on the population and objects of the environment to an acceptable level under the use of secondary fuels derived from SMW.

Chereshnev V., Kirichenko L., Barannikov V., Maslov Y., Varankina S., Khokhryakova V., Safonova D., Dementev S.

Аннотация

The active use of sylvinite constructions in the treatment and prevention of various nosologies made it necessary to search for an objective criterion to predict and control the intensity of the basic physical indices in these devices. In conditions of salt constructions the body of patients is affected by complex hygiene factors, among which the most significant are the natural air ionization and salt condensation aerosol. There is suggested the integrated test “sylvine content in sylvinite fences”, as just sylvine is the major producer of main curative factors of the internal environment of potash constructions. The amount of the mineral sylvine in Silvinite was counted with the use of a specially designed computer software for the analysis of the digital image of salt surface of constructions, which processes the image as pixel by pixel. Investigations were executed out in two sylvinite rooms, differed in sylvine mineral content in salt surfaces. Hygienic indices of the internal environment were investigated with the use of conventional methods. Levels of factors (radiation background, air ionization, multicomponent fine dry salt aerosol, optimal microclimate), affecting on the body of the patients were within a therapeutically significant range and were significantly higher in sylvinite physiotherapapeutic room where the mineral content in sylvinite sylvite fences was by 2.5 times more in comparison with the salt sylvinite device. The results have confirmed the validity of the selection index “content in sylvinite sylvite fences” as integrated one for the implementation of health control of the future performance of constructions consisted of natural potassium salts as in the design as in the choice of material for the manufacture of salt devices.

Ivanenko A., Sudakova E., Skvortsov S., Bestuzheva E.

Аннотация

There was executed the assessment of carcinogen and non-carcinogen risks for population health in some areas of the western, south-western and south-eastern administrative districts of Moscow under the exposure to air borne contaminants whose levels are kept track by various government agencies as part of the socio-hygienic monitoring. The value of chronic non-carcinogenic risks to the health of the population as measured according to the danger index for the combined impact of average annual concentrations of leading air borne contaminants with unidirectional impacts are at near alarming or high level depending on the location of monitoring outposts while for on-off short term exposure to maximum concentrations the impacts are at alarming or acceptable level. The highest danger indices were detected at outposts located near major motorways and industrial facilities. According to monitoring data collected by all agencies the air borne contaminants pose the highest risk to the respiratory organs due to exposure to formaldehyde, air-borne particles and nitrogen dioxide. The extra deaths resulting from chronic exposure to РМ10, estimated by the Moscow Environmental Monitoring make up about 1% of the total mortality rate without bearing in mind of external causes for the population residing in the western, south western and south eastern administrative districts. The total individual carcinogenic risks resulting from the exposure to average annual concentration of a number of carcinogens was found to be between the acceptable and alarming levels. The leading compound contributing to the increased carcinogenic risk is formaldehyde.

Frolova O., Tafeeva E., Bocharov E.

Аннотация

The paper presents the data of the regional characteristics of the zinc content in the soil, products of plant and animal origin in the territory of the Republic of Tatarstan. The soil on the territory of the republic is established to be characterized by low values of the gross content of zinc (from 53.6 to 67.7 mg / kg of dry soil) and mobile forms of zinc (from 9.75 to 12.4 mg / kg of dry soil). This demonstrates the deficiency of this important trace element in the soil. The zinc content in animal products from 20 to 89% less than the average for the reference data, in plant products - from 10% to 360%. The study of nutrition found that the share of diets with normal zinc content is in men - 27.5%, in women - 22.5%. The average value of zinc in the blood serum of the population living on the territory of the Republic of Tatarstan, was 490 ± 40.7 ug / l. This is below the norm. The deviations from the recommended values are observed in all groups, regardless of their level of physical activity. Zinc status of surveyed persons has been below the norm in 80% of cases.

Kandrychyn S.

Аннотация

The aim of the study was to investigate the conjugacy of the spatial distribution of most common helminthiasis (enterobiasis and ascariasis) and tuberculosis between eastern and western regions in Belarus manifested in the different historical periods: 1970-1989 and 2000-2014. The study based on the retrospective collection and analysis of the available information from the annual statistical reports of the national Ministry of Public Health. The paper analyzes a main spatial gradient in the distribution and incidence rates of most common helminthiases and tuberculosis with the regard to historical division of Belarus on the eastern and western parts before the year 1939. Our findings show that East-West differentiation in the prevalence of intestinal parasites and tuberculosis rate on the territory of Belarus may be considered as a result of historical interaction between two different civilizations: the European that has been spread its influence from the West and the Russian Orthodox advanced from the East.

HALOTOLERANCE AEROMONADS ISOLATED FROM WATER AND PERCH (SANDER LUCIOPERCA) IN THE DELTA OF THE VOLGA RIVER

Obukhova O., Lartseva L.

Аннотация

The article presents the results of a study of halotolerance in aeromonads isolated from 447 specimens of perch (Sander lucioperca) and 375 water samples in areas of its habitat in the delta of the Volga River. They were subdominant in the microbial landscape of these biotopes. There were no significant differences inoculation aeromonads found in various parts of the delta. Their halotolerance was studied by means of inoculation of daily pure cultures of meat--peptone broth with 3, 7 and 10% of sodium chloride content and incubation at 37◦C. All the studied microflora of this spieces was established to have significant indices of halotolerance with a predominance in water isolates. Whereby in cases of 3.0 and 7.0% NaCl concentrations were 2.2 times more and in the 10.0% NaCl solution with water and fish strains had similar indices, showing them to be of “marine origin”. Among isolated aeromonads, shattering the water and fish most halophilic strains of A. hydrophila and A. sobria, and halophobic strains were presented by A. caviae. As a rule, water strains had stability indices above in the average of 1.3 times higher than fish ones. Epidemiologically important strains of A. sobria were isolated from water more frequently than from fish, whereas A. hydrophila was isolated as in water as in fish at the same level. Halotolerance of isolated aeromonads in hydroecosystems of the delta of the Volga River had seasonal specificity and dynamics. The gain in halotolerance in aquatic strains of aeromonads in spring and autumn was caused by natural and climatic processes and the elevation in the salinity of delta waters. Enhanced halophilic strains of fish in these seasons is determined by their migration with fish, because in seasons pike migrates from the sea to the river ecosystem.

THE INFLUENCE OF SMALL DOSES OF THE HERBICIDE 2,4-DICHLOROPHENOXYACETIC ACID ON THE BODY WEIGHT OF ANIMALS UNDER THE DIET WITH NORMAL OR HIGH CALORIE

Karmanova D., Chesnokova L., Krasikov S.

Аннотация

There was studied the effect of 6-weeks intake of small doses of the herbicide 2,4-DA on the body weight of animals. The consumption of water containing the herbicide in a concentration of 0.5 MPC was shown to have led to the greater gain of the body weight in experimental rats in comparison with the control. Simultaneously there was noted the gain of the mass of epididymal fat and increase in the concentration of leptin. This effect was more pronounced in rats treated with 2,4-DA, under the diet with high caloric content. The results obtained are likely to be associated with the disrupting action of the herbicide, leading, in particular, to the disturbance of the regulatory function of the thyroid gland and insulin resistance.

Smagulov N., Adilbekova A.

Аннотация

The work is dedicated to methodological problems of the mathematical assessment of the impact of meteorological factors on the adaptive function of the teachers of the High School Institutions. Objects of research. Male teachers of the High School Institution, aged of from 24 to 49 years. Meteorological data were evaluated during the investigation of anthropometric indices of height and weight, individual-typological features and the physiological assessment of the central nervous system, cardiovascular system of the High School teachers. Statistical analysis was performed with the use of Statistica 6.0 package and special statistical software. Paired correlation coefficients obtained as a result of calculation were used to estimate the proportion of the influence of input factors (arguments) on the output factors (functions). A mathematical analysis has allowed to reveal leading meteorological factors that cause a certain level of functional exhaustion during the investigated period. The use of a non-linear correlation analysis allowed to enhance significantly the ability for analytical processing of the results, increase of the effectiveness and the possibility of interpreting the interaction of factors in achieving optimal adaptation of teachers in the working process and to identify the role of meteorological factors in this process. Knowledge of leading factors and the percentage of their contribution to the functional state allowed to give the more accurate assessment of stress to the organism in specific circumstances. The ultimate aim of the mathematical analysis should be not only to find the critical value defined the priority factor characterizing the degree of of information load, but the critical combination of all priority factors causing disruption and the beginning of “start-up” adaptation process in the system “dose-effect. “
