Pushkarova I. Improvement of integrated assessment of ecological status and protection methods of technonatural systems from heavy metals pollution

The dissertation is devoted to the improving of the ecological monitoring control methods at the environment state, on the base of complex estimation of ecological state of Chernigov technonatural systems around 3 ecological danger works by integrated coefficient of ecological danger (In, in ball).It include the integrated rates of technogenous contamination, especially by heavy metals: atmosphere air - Kn, soil - Zc and accumulation heavy metals by plants - Kac, the integrated index of surface water contamination (r. Desna, Strigen, Bilous). The resistance corrosion rates of construction metals (steel, Al) of technical structures for the first time have been introduced in the complex integral estimate of ecological state technonatural systems soil, river water - KCM а.о., which characterized ecological danger of the technogenous accidents. For their prevention synergist protective compositions of complex action with the active polydentatic chelatoformators have been developed. They convert the mobile forms heavy metals in non-mobile to formation of the stable metalochelating in soluble complexes. It is suppressed accumulation heavy metals by soil and water biota and increasing (with diminution Zc, index of surface water contamination) corrosion resistance construction metals and considerably rise the exploitating reliability of technical structures by the surface modification with strong protecting nanostructuric membranes, which are isolated from the aggressive action of medium. It is reached the considerable decreasing of the levels of the technogenous influence on technonatural systems and creation of conditions for prognosis diagnostic of the ecological risks, safety of human life and optimization of ecological safety management. Results of the work have been found on industrial utility and educational process.
