Wpływ nielegalnych wysypisk odpadów na niektóre właściwości gleb na terenie gminy Kobylanka

Abstract

The study confirmed the impact of uncontrolled dumping waste sites on some chemical properties of soil, particularly in the surface layers. It manifests itself as: the change in pH within the landfill as compared to adjacent areas, increase of conductivity indicated on the higher salinity of soil, increase of organic matter content resulting from the deposit of organic waste, increased content of C and N and the extension of C:N ratio, which indicates on reduced ability of microorganisms to the processing of organic matter and increase in soil additives in the form of glass, metals, plastics, which can contribute to degradation of soils. The wastes stored at the surveyed illegal dumping sites within the area of municipality Kobylanka not significantly affected the heavy metal contamination of soils. The most of soil samples shall be eligible for the soils with the natural category of Cr, Cu, Hg, Ni, Pb and Zn content. Only a few samples of soil were classified to category with increased content of Zn, Cu, Pb and the average of Ni and Cr.
