Miroshnychenko M. Soil sustainability as a basis of pedoecological normalization of pollution

Object of research - stability of soils to pollution by different chemical substances (heavy metals, hydrocarbons, alkaline and alkaline earth metals). The purpose - development of the theory of soils' stability to effect of external factors, development of methodology of ecological normalization of chemical pollution of soils, creation of scientific bases of an estimation of danger of pollution with using of soil-adapted and functionally-differentiated systems. Methods - experimental simulation, field, landscaptive-geochemical, and laboratory-analytical. Theoretical results - the methodology and a terminology of the doctrine about soils' stability is advanced, classification of soils on their stability to heavy metals and scientific bases of pedoecological normalization is developed, the theory of aggregate stability of a thin-dispersed part of soil is advanced. Practical results - the Concept of ecological normalization of anthropogenous loading on a soil cover; methodical recommendations "Soil-geochemical inspection of urbanized territories"; the standard of the State committee of natural resources of Ukraine SOU 731-41-10.01:2004 Preservation of the environment. An estimation of soils' pollution and determination of losses of an agricultural production as a result of deterioration of the land areas during a construction of petroleum both gas boreholes and branch standard BSTU 41-00032626-00-023-2000 Preservation of the environment. The recultivation of lands during a construction of petroleum and gas boreholes; techniques of definition of aggregate stability of soil and determination of contents of mineral oil in soil by infrared spectrometry (MD 31-497058-014-2003 and MD 31-497058-009-2002). Novelty - functional and modal stability of soil is allocated, presence of feed-forwards and feed-backs between them and their value for normalization is determined; principles of soils' classification on their stability to heavy metals are developed and three basic classes is allocated; principles of determination of aggregate stability of a thin disperse part of soil, and change of this property under effect of external factors are fixed; the methodology of a regulation of soils' carbohydrate pollution is developed; necessity of transition to soil-adapted and functionally-differentiated systems to an estimation of pollution is proved. The degree of introduction - the Concept is put in a basis of creation of the State scientific program, the developed standards are used for preservation of the environment in oil-and-gas area, Methodical recommendations and techniques of measurement - at scientific researches and in practice of soils' protection. Sphere - scientific-educational and nature protection.
