[Methodical issues of the monitoring for ammonium in indoors air].

Introduction. To perform mass studies of the indoors air environment of the ammonium content the actual issues are the shortening of the sampling time and material costs for their implementation, reduction of adverse effects of ammonium with keeping of the objectivity of results. Aim. The elaboration of the method of short-term air sampling for indoors ammonium and comparative assessment ofdifferent methods of sampling in the course of modeling and field tests. Materials and Methods. Air sampling for ammonium was carried out according to the developed program and standard method, under the average daily 4-fold taking according to State Standards (GOST) 17.2.3.01-86 andRD 52.04.186-89. The evaluation of the significance of deviations of analysis results was carried out in accordance with GOST R ISO 5725-6-2002 and Recommendations of the Interstate Standardization RMG - 61-2003. Results. There were executed model and field tests of air sampling for ammonium according to the standard method and the program of short-term sampling. There were obtained significantly comparable results of ammonium content in the indoor air in the course of model and field tests. Conclusions. Sampling according to the developed program has a number of advantages, including: the shortening of sampling time, material costs, increasing in productivity in the analysis of indoor airfor the ammonium content. The execution oftest sampling according to the developed program allows to reduce the time of ammonium exposure to personnel carrying out the test sampling.

[Experience of the implementation of the method of the integral assessment of drinking water on indicators of chemical harmlessness in St. Petersburg].

Providing population with quality drinking water--one of the priority tasks of the state policy aimed at maintaining the health of citizens. Hygienic rating of the drinking water quality envisages requirements to assurance its safety in the epidemiological and radiation relations, harmlessness of chemical composition and good organoleptic properties. There are numerous data proving the relationship between the chemical composition of drinking water and human health, and therefore the issue of taking a hygienically sound measures to improve the efficiency of water treatment has more and more priority. High water quality--the result of complex solution of tasks, including an integral approach to assessment of the quality of drinking water the use of hygienically sound decisions in the modernization of water treatment systems. The results of the integral assessment of drinking water on the properties of harmlessness have shown its actuality in the development and implementation of management decisions. The use of the spatial characteristics of integrated indices permits to visualize changes in the quality of drinking water in all stages of production and transportation from the position of health risks, evaluate the effectiveness of technological solutions and set priorities for investing.

[On the problem of assessment of occupational health risk in personnel performing intense visual work].

In the work an there is given an assessment of the working conditions during intense visual activity without the use of displays medium and optical devices. It is proved that the indices of evaluation of the light environment in accordance with "Guidelines for hygienic assessment of factors working environment and labor process" P 2.2.2006-05 R 2.2.2006-05 were substantiated to be been supplemented by indices of uneven brightness and color temperature of the light source. It is confirmed that the intense visual work is a meaningful evaluation of the constraint, especially in terms of sensory loads. In the dynamics of the working day there was revealed the deterioration of the visual analyzer and psychoemotional state. In periodic medical examinations there was noted a marked gain in revealed pathology of diseases of the eye and adnexa with increasing work experience. A method for estimation of the risk in people doing intense visual work, taking into account the evaluation of the light environment, intensity of work, dynamics of the functional state during the shift has been proposed.

[Modern problems of the application of sanitary regulations concerning sanitary protection zones and sanitary classification of enterprises, buildings and other facilities].

In this paper there was performed an analysis of the application of sanitary norms and rules concerning sanitary protective zones and sanitary classification of enterprises, buildings and other facilities, including requirements for the sufficiency and accuracy of information in the performance of projects in sanitary protection zone (SPZ). There is presented an analysis of regulations that set requirements for implementation of mapping works in drafting the SPZ. The design of the SPZ was shown to be, on the one hand, the element of territorial planning subjects of the Russian Federation, on the other hand, the object of capital construction. The substantiations of requirements for graphic and text content, structure, and composition of data, sources of their obtaining, methods of data convergence are reported. There are revealed inconsistencies in Sanitary Regulations and Norms (SanPins) and in their relationship with the Town Planning and Land Code and other laws, and regulations adopted in their development.

[Features of the regulation of legal relations in the field of sanitary and epidemiological welfare in the Eurasian Economic Community member-states].

The aim of this work was identification of both general trends and approaches, and the differences in the regulation of relations in the field of sanitary and epidemiological welfare of the population, determination of the necessary measures to harmonize legislation states in the countries - members of the Eurasian Economic Community (EurAsEC) in the noted sphere. As a result of the present research recommendations about unification and harmonization of legislations in member states of EurAsEC are developed for formation of uniform economic policy in noted sphere.

[Hygienic basis for combined models assessing occupational risks].

Occupational risk methodology enables to forecast probability of occupational and nonspecific diseases, to determine length of service load on workplaces and for occupations, increases role of preliminary and periodic medical examinations, therefore helping to solve problems of workers' health care.
