Abstract

Species of macrofungi were collected from extremely polluted sampling spots in the vicinity of abandoned antimony mines in Slovakia. Concentrations of potentially toxic elements in plants and fungi were determined by ICP-MS and in soils and sediments by both ICP-MS and ICP-ES. Of the edible species the highest values of arsenic and cadmium were recorded in Agaricus arvensis, lead in Imleria badia, and species of the genera Boletus, Leccinum, and Suillus accumulated high levels of mercury. Suillus species also accumulated high levels of antimony and chromium. Bioconcentration factors were calculated for selected species and antimony, cadmium, and mercury were accumulated by most of the sampled species. Based on our results, Cardamine amara belongs to accumulators of potentially toxic elements. We do not recommend the consumption of edible mushrooms and medicinal plants from the studied localities, as they may pose a risk of intoxication for humans. [ABSTRACT FROM AUTHOR]

Abstract

Weathering of open adits, dumps and non-isolated tailing impoundments at abandoned ore deposits cause many problems such as water, soil and stream sediments contamination by potentially toxic elements. Soil contamination often results in a local change in biodiversity. In the present study, we describe the diversity of plants and fungi in the areas contaminated mainly with arsenic and antimony. The highest contaminant contents (As, Sb, Pb, Zn, Cu) in soils were generally identified in alluvia of draining streams. In the soils, Sb and As are mainly bound in the structures of secondary Fe or Sb oxides and oxyhydroxides, which arise due to the oxidation of suldfidic minerals in soils in situ (precipitation from soil pore solutions). Phytosociologically, plant communities on anthropogenically significantly affected habitats - old mining dumps and ponds - differ significantly from those characteristic of the given type of vegetation zone on unpolluted substrates. Fungal diversity at the contaminated areas is realtively high and does not seem to differ from the surroundig habitats. However further research for the longer period is required to evaluate the whole mycobiota in its complexity. [ABSTRACT FROM AUTHOR]
