Ecological hygienic assessment of soils quality in urban areas

Assessment of the soil quality is of prime importance essential for the characterisation 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. In this study, the authors undertook a 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 of food, 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.
