Environmental assessment of soil Syzran

Zhukova Maria Vladimirovna  (postgraduate student, Ulyanovsk State University, Ulyanovsk, Russia)

Introduction. Due to anthropogenic loading in the natural and anthropogenic complexes (NAC) now ecological assessment of state of environment to become more and more relevant. Materials and methods of a research. Sampling was made in residential, industrial and park zones. Methods of an ultra-violet luminescence, are applied to definition of oil products, and atomic and absorbing spectrometry, to definition of toxic metals. Results of a research and their discussion. Excess of background level on the content of oil products is revealed on sites of industrial zones of JSC Oil Refinery, JSC Samara Terminal (excesses have made by 4 times). Essential pollution of soils oil products is noted also in the neighborhood of the village of Uvarovka (excess twice). In residential territories such heavy metals as zinc, lead, copper prevail. The average and maximum content of fluorine, nitrates and sulfates in the soil of the studied objects have made tenth-hundredth shares of maximum allowable concentration (0,02 - 0,60 maximum allowable concentrations). For these substances any case of excess of threshold limit values isn't registered. Conclusion. Researches on studying of an ecological condition of soils of the city of Syzran have allowed to obtain data on maintenance in them gross forms of oil products and heavy metals. The condition of soils of industrial territories is satisfactory, gross contents on some heavy metals, on average by 1,5-4 times, exceeds threshold limit values. The explored territory can be characterized as the territory of moderate risk in which continuous monitoring of an ecosystem is necessary.
