Abstract

Systematic geochemical study and mapping in Slovakia, allowed to understand distribution of potentially toxic trace elements in various natural media (soil, rocks, stream sediments, groundwater and forest biomass) related to geogenic and anthropogenic sources. Anomalous concentrations of chromium and nickel of geogenic character were detected in soils developed on flysh sedimentary rocks. The main interest devoted to such soils is motivated by possible toxic effect of chromium and nickel on plants and subsequently impact on living organisms and humans. The aim of this contribution was to assess the level of chromium and nickel concentration in assimilation organs of trees (needles). It was found high content of these elements in some soils. The studied sites were Podolínec, Forbasy, Stará Ľubovňa, Drienica, Kamenica. Content of these elements in needles of Norway Spruce (Picea abies) and Scots Pine (Pinus sylvestris) were very high on geogenically contaminated soils with higher values in more in the acidic soils with lower values of pH.

Key words: chromium, nickel, soil, needles, Šambron Member, Western Carpathians
