| Popis: | The dump-fields Podlipa and Reiner at L’ubietova abandoned Cu-(Ag) deposit is situated at the boundary of the village settlement. The heavy metal contamination of the technogenous sediments and soils at the investigated dump-field show irregular planar distribution. Also the heavy metal content in the surface water, drainage water and in the groundwater was studied both in the dry as well as during the rainy periods. The speciation of As and Sb showed that there are present both As3+, Sb3+ as well as the less toxic As5+ and Sb5+ species. In the sediments prevail As5+ and Sb5+ species while in the water is dominant the As3+ and Sb3+ form. The article also presents results of the plant tissue degradation study in heavy metal contaminated conditions and compares them with those from reference sites. The cementation process causes substitution of iron by copper. The technogenous sediments and the contaminated soil of the dump show only very limited acidification potential. The installation of the Fe0-barrier seems to an acceptable solution for cleaning of the underground water. |
