    Abstract:
    The surrounding of the poorly maintained tailing ponds is endangered by the toxic substances and represents a serious risk for the health of the local population. The aim of the study was to determine the soil pollution by the hazardous elements (As, Cr, Cd, Cu, Fe, Mn, Ni, Pb, Zn) around the tailing pond using contamination factor (Cf), degree of contamination (Cd) and pollution load index (PLI). The health and the condition of soil were evaluated by soil enzyme activity (urease, acid and alkaline phosphatase, florescein diacetate, and ß-glucosidase). The spreading of the airborne hazardous elements from the body of the tailing pond was evaluated by moss and lichen bag technique and relative accumulation factor was used for the result expression. Cd, Fe, and Mn in soils reached above the limit values at all sampling sites. According to the degree of contamination (Cd), the soils at the sampling area were very high contaminated by As, Cd, Cu, Fe, Mn, Ni, and Pb. The most part of the assessed area was according to the PLI values extremely polluted. The air pollution was the most serious around the tailing pond, but serious levels of some hazardous elements were determined also in the remote distances.
