The purpose of work: is a reception of new experimental data and carrying out of a theoretical generalizations concerning to processes of accumulation of heavy metals in various components of the surrounding natural environment and processes of migration of elements between these components with the purpose of the forecast of a condition and studying of opportunities of restoration of the natural environment by natural way. Method of research - the chemist-X-ray fluorescent analysis of heavy metals concentration in components of landscapes and the mathematical modeling of ecological condition of natural landscapes dynamics. The review of theoretical methods of modeling of development and evolution ecosystem in conditions of a constant technogen and anthropogenous press is carried out. Existing models of processes of migration of heavy metals in components of landscapes and methods of a quantitative estimation of parameters of these models are considered. The review and the analysis of a modern condition of methods, means and equipments for quantitative definition of the heavy metals contents in components of an environment is executed. The substantiation of expediency of use for complex research of landscapes components of a method X-ray fluorescent analysis (XFA) is carried out. The general questions of XFA metrology are considered and calculations of metrological parameters are carried out by the example of measurement of the heavy metals contents in the certificated standard samples of the materials used in problems of the environment preservation. Three complex ecological expeditions on reservoirs and water-currents of pool r. Syverskiy Donets are carried out. The significant new actual material on a wide network of the data gathering which confirming high level of concentration of heavy metals practically for allpoints of sampling is received. Recommendations on use of results of the SRW are formulated. The especial attention is given to questions of monitoring throughborder channels.
