Study of the impact of recultivated granite stone quarry dumps on the environment and agricultural land in the Leningrad region

Abstract

Abstract The environmental condition of the granite stone quarry dumps and the adjacent areas of Kuznechnoye village in the Leningrad Region of the Russian Federation was evaluated based on the results of field measurements of dust concentrations in the air (fraction size 1-10 microns) and analytical determination of chemical element contents in soil samples by spectral emission analysis and X-ray spectrometry methods. It has been established that dusting of unreclaimed dumps under conditions of humid climate, which is observed most of the year, and high pH values of soils leads to the formation of polyelement technogenic geochemical anomalies of Pb, Zn, Cu, Ba and Sr. The data obtained can be used in the selection of the most effective method of reclamation of dumps.
