Ecological Aspects as a Basis for the Formation of Sustainable Development of Technogenically Loaded Areas

Abstract

The purpose of this work is to identify the environmental aspects of poultry farming complexes and develop environmental measures that help prevent man-made impacts on environmental components and restore groundwater quality. Materials and methods. The study is based on an expert examination of primary sources of pollution (poultry farms) located in the right-bank part of the Lipetsk industrial district, soil sampling in agricultural fi elds irrigated with industrial clarifi ed wastewater. Results and discussion. According to the results of research in the areas of poultry farms, namely in the central, northwestern and western parts of the studied area, a high level of terrain fragmentation with maximum values of 0,5- 0,7 km/km2 was revealed. Within the Lipetsk industrial district, under the infl uence of intensive poultry farming, zones with persistent excess concentrations of nitrates up to 3,1 MPC have been formed. For a number of chemical elements in soils irrigated with clarifi ed wastewater, background values exceeding 10-30% were detected. This environmental problem requires the development and implementation of management solutions aimed at improving the quality of groundwater in the operated Zadonsko-Yelets aquifer complex. Conclusion. According to the results of the conducted research, the sources of pollution are systematized according to the degree of negative impact, among which primary and secondary ones are distinguished, which differ in a complex of environmental aspects. Natural factors that enhance the transformation of groundwater quality have been identifi ed. Environmental protection measures are proposed for the selected groups of economic entities.
