Assessment of the soil quality is ofprime importance essential for the characterization of the ecological and hygienic condition of the territory, as the soil is the first link of the food chain, the source of secondary air and water pollution, as well as an integral index of ecological well-being of the environment. Herewith the qualitative analysis of soil complicated by the specifics of the soil genesis in the urban environment, in which an important role is played by manmade land bulk and alluvial soils; the inclusion of construction of material debris and household garbage in upper horizons; the growing up of the profile due to the perpetual introduction of different materials and intensive aeolian deposition. It is advisable to consider the currently neglected question of the study of soil vapor containing volatile chemicals. These pollutants penetrate into the building through cracks in the foundation and openings for utilities. Soil evaporation may accumulate in residential areas or in the soil under the building. Because of this, it is necessary to pay attention to the remediation of areas allocated for the built-up area, possessing a large-scale underground parking. Soil contamination is the result of significant anthropogenic impacts on the environment components. In general, about 89.1 million people (62.6% of the population of the country) live in terms of complex chemical load, determined by contamination offood, drinking water, air and soil. The list of microbiological and sanitary-chemical indices of the assessment of soils of urban areas may vary in dependence on the data obtained in pilot studies due to changes and additions to the assigned tasks. Timely forecast for the possibility of the usage of released lands of urban territories for the construction and the creation of new objects for different purposes should become the prevention of chronic non-infectious diseases in the population residing in urban areas.

One of the main criteria which determine the possibility of the use of a particular type of ice-melter reagents (IMR) is the degree of their safety for the environment and human health, which is reflected in the establishment of safe doses and concentrations. In this regard, the current area of research is to improve the ecological and epidemiological principles of risk assessment of modern types of anti-icing agents. Currently available data concerning monitoring soil studies and the snow held in various cities of Russia, show that there is a process of accumulation of the main components of IMR - sodium and chlorine ions in the areas related to the roadway. The article is designated a problem of existing methodological approaches to the assessment of the phytotoxic impact in the investigation of anti-icing agents in the laboratory. There was executed the comparative characteristics of the results of the preliminary pilot studies on the phytotoxic properties of IMR under using different substrates for germination of seeds - soil and filter paper. The data obtained are characterized by differences in the degree of phytotoxic action of the same species depending upon ice-melter reagents methodical setting circuit laboratory experiment. As a result, there was shown the imperfection of the existing method of rapid analysis in relation to ice-melter materials (IMM).

Introduction. Taking into account the prevailing urban planning situation, the residential area has almost come close to the burial sites. Justification of the possibility of a safe interposition for the population of residential and “zones with special conditions for the use of territories”, to which the sanitary protection zones (SPZ) are referred, requires scientific and methodological study due to the lack of normative fixation of the procedure. The purpose of the study was the hygienic assessment of burial sites as sources of environmental pollution, the development and practical testing of methodological approaches to substantiating the size of the sanitary protection zone, the admissibility (inadmissibility) of placing normalized, in accordance with the requirements of sanitary legislation, objects in the SPZ cemeteries. Materials and methods. The design and technical documentation were studied, the analysis and assessment of the obtained data on the quality of environmental objects on the territory and boundaries of the SPZ of the cemetery for compliance with sanitary and epidemiological requirements and hygienic standards was carried out. Results. To substantiate correctly the hygienic requirements for the conditions of burial and the safe operation of cemeteries, excluding the possibility of their negative impact on the health of the population, a comprehensive sanitary and chemical assessment has been developed with the determination of the degree of influence of burials on environmental objects. An algorithm for the formation of the evidence base for the absence (presence) of the negative impact of the fact of the location of residential buildings in the sanitary protection zone of cemeteries is proposed. A step-by-step assessment mechanism has been worked out including identification of hazards, instrumental measurements of the quality of environmental objects, selection of priority pollutants and objects (sources) that pose a threat to public health. Limitations. The research was carried out for the territories of cemeteries, it includes an assessment of the sources of environmental pollution specific to this type of burial. The methods used for this study are used to assess soil, groundwater, and atmospheric air. Conclusion. The proposed procedure, tested in real conditions of a large city, makes it possible to form the criteria and priorities of the evidence base for making a decision on the assessment of the hazard (safety) of the placement of residential buildings and other standardized territories within the boundaries of the existing sanitary protection zones of cemeteries.
