PROBLEM-SOLVING ARTICLES
On the scientific and methodological support of the assessment of the performance and effectiveness of the control and supervision activity of the Federal Service For Surveillance On Consumer Rights Protection And Human Wellbeing
Abstract
The changes in socio-economic conditions of the modern world require the public authorities to improve the methods of management. The index of the effectiveness of this management is the achievement objectives of public interest. Based on historical data, taking into account recommendations of international organizations for the assessment of the performance and efficiency of Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing it is proposed to use infectious morbidity rate indices of the population controlled by means of vaccination; the level ofparasitic diseases; the percent ofprevented cases as a result of the activities of agencies and organizations of Federal Service For Surveillance On Consumer Rights Protection And Human Wellbeing, mortality rate due to the impact of environmental factors, percent ofprevented cases as a result of the activities of bodies and organizations of Federal Service For Surveillance On Consumer Rights Protection And Human Welbeing, the prevalence rate of diseases associated with neoplasms in the population, diseases of the circulatory system, asthma, liver disease, congenital abnormalities (newly diagnosed malformations, deformations and chromosomal abnormalities) and the value of economic loss, generated by medical and demographic losses and underproduction of Gross Domestic Product prevented by measures of Federal Service For Surveillance On Consumer Rights Protection And Human Wellbeing. Methodological approaches for monitoring and analysis of these indices have been developed. There are determined ways of the improvement of the system of collecting and processing information for the correct assessment of the performance and efficiency of service activities.

ENVIRONMENTAL HYGIENE
Conceptual assignment and experience of the task solution for optimization of supervisory activities in the field of sanitary and epidemiological welfare of the population
Abstract
In the article there is considered the problem of optimization of the control and supervision activities of the Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing on the criterion “prevention of the economic damage”. In the process of the solution of the multi-objectives optimization the task was reduced to one-criterion, to be solved by the methods of mathematical programming. The results were obtained by the use of main criterion methods and successive concessions. The problems were solved with the help of MS Excel means, by using “Search solution” tool. Testing of the solution of the problem was performed on the statistical data at the federal level. The optimal performance indices of the activity of agencies and organizations of Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing were acquired for the script, which preserves the existing level offunding. The use of an optimal model of action allows to predict an increase by 38% of prevention of economic losses from underproduction of Gross Domestic Product due to the loss of health of economically active population of the country at the same cost to the supervisory activities of Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing. The solution of problems of optimization by the criterion offinancial costs of activities of the Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing has shown that the reduction in funding of control and supervisory activities of the Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing even in case of the system of measures ’ optimization could have the effect of lowering the total avoided economic loss. The latter indicates to the relevance of the maintenance of the level of providing health surveillance when improving its structure and organization.

The assessment of environmental quality and risks for thepopulation of the city of Zakamensk - territory of long-term storage of waste of dzhidinsky tungsten-molybdenum combine
Abstract
The long-term storage of the waste of the past activity of Dzhidinsky tungsten and molybdenum combine (DTMC) in the territory of the Republic of Buryatia, city of Zakamensk, was shown to become a reason of the high content of suspended solids, lead and the constant presence of heavy metals (cadmium, nickel, chromium, etc.) in ambient air. In case of the regulatory water quality of centralized water supply system, the city is distinguished by high levels of heavy metals in the water ofpublic and private wells. The high concentrations of heavy metals in soils of the city have been registered. Locally produced food products comply with hygiene requirements, but in the plant and in the dairy and meat products the heavy metals are registered in the relevant concentrations, the combined effect of which generates higher levels of risk (HIfo up to 1.60). The presence of the components specific to the DTMC waste in all objects of the environment generates unacceptable for the residents carcinogenic risk (TCR up to 1.5*10-3) and non-carcinogenic risks of disorders of the respiratory function, central nervous system, blood system, the endocrine system and etc. (total hazard index (THI) accounted of up to 17). Priority risk factors are associated with chromium, lead, copper, manganese and cadmium particles entering the body with the atmospheric air, drinking water and localfood products.

On the update of the sanitary classification of objects of oil production, preparation and primary oil refining (from the experience of designing of sanitary protective areas)
Abstract
There are given results of generalization of designing materials for sanitary protective areas of objects of the oil production, preparation and primary oil refining. It is shown that as a result of manufacturing technology enhancement, renewal of the hardware park and implementation of air-security actions aiming at exhaust fumes reduction and the reasonable use of passing oil gas, considerable changes happened over the last decade as regarding the impact of objects on the atmospheric air and population health. The accumulated expertise of designing and concordance of the projects of sanitary protective areas for the oil production, preparation and primary oil refining objects confirms that for the majority of objects of approximate sizes of sanitary protective areas determined by the actual sanitary norms and regulations are excessive. Single and average daily maximum concentration limits as well as allowed levels of cancerogenic and non-cancerogenic risks for the health of the population are provided at the distances from the borders of construction sites which are considerably less than the ones determined by the sanitary classification. Calculation data is confirmed by results of the systematic instrumental research. There are given guidelines to introduce changes in the sanitary norms and regulations. For a number of objects it is suggested to keep the existing classification.

Analysis of cause-effect relations of the levels of biological markers of exposure to heavy metals with their personalized loading dose in the areas of wastes’ influence induced by the operation of the metallurgical plant in the past
Abstract
The article analyses and demonstrates methodical approaches to the practical implementation of the one of key stages in the formation of the evidential base of hazard to health caused by the negative impact of environmental factors. The stage comprises the establishment of the causal dependence (proven relation) of the chemicals’ content in biological media of exposed population on the personalized loading dose. The experiment included the local population (224 cases) living in the area of the exposure of the Dzhidinsky tungsten-molybdenum combine waste (Republic of Buryatia). The cartographic association of the residential areas of the population has been made as well as the approximation of the field study data of environmental factors due to 7 heavy metals has been performed. The total personalized loading dose caused by exposure to lead, cadmium, nickel, chromium, zinc, copper, manganese (the wastes of the metallurgical plant) was calculated. It is evident that the poor quality of the environment leads to the contamination of biological media (blood) by chemicals. More than 90 significant biologically-based mathematical models of the system “exposure - exposure marker” have been received. On the example of cadmium there was established the total dose of 0.0003 mg /(kg*d) for the child population, the excess of which significantly increases chances of both exceeding the concentration of a substance in blood over the control level and leading to the formation of a stable causal relationship with exposure markers of the multimedia load.

Space-time analysis of risk to public health under the exposure to urban noise (on the example of Perm)
Abstract
The study included acoustic calculations carried out on the territory of the assessment within the boundaries of the settlement area of the rectangle with the square 5.6 km2, containing more than 1200 linear noise sources, 2514 nodal points, 138 calculation points. In addition, in reference evaluation points there were performed instrumental measurements of noise levels in the study area, where more than 60 thousandpeople live. Calculated and instrumental noise pollution levels were associated by means of an approximation method. As a result of coupling computational and instrumental data 4 zones with different levels of potential chronic acoustic impact on the population were allocated. With the use of mathematical models of risk the trend of the formation of moderate, high and very high risk was determined in certain areas within the boundaries of the territory. Under the noise influence over 74% of the population were shown to live in conditions of unacceptable health risk. The critical points of a qualitative change in the risk levels moderate - high - extremely high were set, which is for the worst 4th zone is 7, 30, 40, respectively. To reduce noise levels the study suggested measures, the efficiency of which reaches 27 dBA.

On the evaluation of living conditions and health status of residents in precast framed houses of the micro-disrtict Usolsky-2 (the city of Berezniki, the Perm region)
Abstract
There are given results of instrumental studies of the air of 77 living rooms of precast framed houses of the microdistrict Usolsky, the Perm region, Russia. There were used materials emitting formaldehyde, phenol and other chemical impurities into the environment. In 90% of rooms levels offormaldehyde were shown to be systematically registered as by 1.5-10 times exceeding the hygienic average daily standard (0.01 mg/m3). Revealed concentrations create health risks to residents, which can be evaluated as unacceptable: lifelong cancerogenic risk made up about 2.8*10-4, non-cancerogenic risk for respiratory organs disorders accounted of 8.7HI. Profound studies of residents ’ health showed the increased level of respiratory diseases in adults living for 1.5-3.0 years in observed houses. The group of the exposed people of the micro-district Usolsky was characterized by significantly higher consistent blood level of formaldehyde (3-7 times higher than in the comparison e group), and the presence of negative prenosological changes of several laboratory indices, including some of indices which testify both to general and specific sensitization to formaldehyde and the risk of the development ofproliferative processes. There are given suggestions concerning the guidelines to arrange primary and secondary preventive measures against potential health disorders of the residents of the micro-district.

HYGIENE OF CHILDREN AND ADOLESCENTS
The disorders of physical development of children residing in the conditions of low-level contamination of the atmospheric air and drinking water by metals (lead, manganese, nickel, chrome, cadmium) on the example of the Perm region
Abstract
There was executed a clinical laboratory study of 183 children residing in the conditions of constant low-level impact of a complex of such consumed from atmospheric air and drinking water metals as lead, manganese, nickel, chrome, cadmium) and 46 children residing in the conditions of sanitary-hygienically wellbeing of the habitat. The evaluation of Total Hazard Indices (THI) for conditions of chemical substances entering with atmospheric air and drinking water have revealed the excess of accepted values (THI>1) regarding to disorders of the central nervous system in children (THI amounted for up to 4.93) and disorders ofendocrine system (up to THI of 1.13). The results of chemical-analytical researches showed the blood content of lead, manganese, nickel, chrome, cadmium in children living in conditions of low-dose complex load to exceed the reference level by 1.3-2.2 times. In persistent multi-medium polymetallic load the number of children having physical development disorders was found to increase up to 1.2-1.6 times (body weight deficiency - up to 16.5%). There is determined a verified direct probabilistic relationship of cause and effect ofphysical development disorders in children with high blood content of manganese, nickel, and chrome. Exceeding content of lead, manganese, nickel, and chrome (1.3-9.4 times higher than the reference level and the comparative group) in bio-media of children makes a negative impact on the central and autonomous nervous system, creates disorders in protein-synthetic processes in liver, form early shifts of hypothalamo-hypophyseal regulation with further deterioration of physical development indices.

OCCUPATIONAL HYGIENE
Biomarkers of work-related endothelial dysfunction in employees of ore-dressing production occupied in conditions of long-term noise exposure
Abstract
The article demonstrates the methodical approach to the justification of biomarkers of adverse effects (for example, endothelial dysfunction) in workers of sylvinite ore-dressing production occupied in conditions of the long-term noise exposure at the level of 85-95 dBA. The methodology testing revealed that the professional risk in workers of basic specialties is estimated from mild to unbearable by the criterion class of working conditions (3.1.-3.3.). Hypertensive heart disease is a most often occupationally conditioned disorder (RR = 8.69, DI = 2.53-29.83; etiological fraction (EF) = 88.49%). Endothelial dysfunction, pathogenetically related to the development of hypertension, has a high degree of occupational conditionality in terms of a reduced level of K-brachial artery sensitivity to stress and a reduced level of the relative increase in the brachial artery diameter. Biomarkers of endothelial dysfunction (in terms of reducing the relative increase in the brachial artery diameter) are elevated serum levels of TSH, MDA, IL-10, lipoprotein (a) in respect to the physiological norms. The reasonable biomarkers of negative effect allow to expand the evidence base of industrial conditioning of disease process in workers at individual and group level at the determined noise exposure.

METHODS OF HYGIENIC AND EXPERIMENTAL INVESTIGATIONS
Modern analytical techniques in the determination of highly n-nitrosamines in biological fluids (blood)
Abstract
There are given results of experimental research on the development of the high-sensitive and selective chromato-mass-spectrometric methodfor the detection of the N-nitrosamines (N-nitrosodimethylamine andN-nitrosodiethylamine) in blood with the use of distillation and automated system of solid-phase extraction Sepaths (Italy) on the cartridges Coconut 6 cm3 at the stage of sample preparation. Chromato-mass-spectrometric analysis of the extract allowed the detection of the completeness of extraction of N-nitrosodimethylamine from blood equal to 98.5% and for N-nitrosodiethylamine - to 100%.The developed chromato-mass-spectrometric method for the detection of N-nitrosamines in biological media (blood) allows the execution of the control of contents of N-nitrosodimethylamine and N-nitrosodiethylamine in the concentration range of 0.002 - 0.1 mg/dm3 at error not more than 27%. The usage of the developed method for the detection of blood N-nitrosamines levels in groups of the observed child population consuming drink water with different content of nitrates allowed to determine a verified difference and excess of N-nitrosamines content by 2.8 times in the group with higher nitrates content in the drinking water as compared to the group of observed cases who drink water with standard content of nitrates. In order to confirm the presence of the defined N-nitrosamines in the blood samples of the people under research there was executed chromato-mass-spectrometric identification in the SCAN mode. Mass spectrums of N-nitrosodimethylamine and N-nitrosodiethylamine discovered in blood samples of observed cases were compared to mass spectrums of NIST 08.L library. The results of identification of N-nitrosodimethylamine and N-nitrosodiethylamine in the blood samples showed that determined compounds have the same structure as the ones given in the library. The method can be used for biomonitoring, sanitary-epidemiological examinations, and researches in evidentiary medicine in order to determine the impact of the unfavourable anthropogenic factors.
