Chromium and Nickel Accumulation by Plants Along an Altitudinal Gradient in Western Carpathian Secondary Spruce Stands

Abstract: Our research was realized in segments of 80-year-old secondary spruce ecosystems selected in the buffer zone of Slovenský raj NP (western Carpathians). The vertical transect (635-1,110 m a.s.l.) consisted of three localities with six geobiocoenological plots. The Cr contents (mg kg R. idaeus, D. dilatata, S. ovatus, S. virgaurea) rooted in surface horizons of Cambisols were higher than 1, thus pointing at the impact of soil contamination. Cr TC higher than 1 were found for D. dilatata (2.4) and V. myrtillus … Show more

“…There were significantly higher concentrations of Hg, Cr and Ni in roots than in aboveground parts in almost all sampling stations, while TF values were below 1.0, with two exceptions. This means that nettle roots served as a biogeochemical barrier for all three elements, which is consistent with previous studies [21,23,25]. Mercury concentrations in the aboveground parts were always below 0.05 mg/kg and BCF values were quite low.…”

“…Despite its low availability, Cr was present in the aboveground parts of the plant in concentrations that exceeded the respective reference concentration in plants according to [46] (Table 2). Several studies evaluated the transfer of soil Cr to plants and also recorded its minimal migration with BCF values below 0.1 [13,21,23]. From the point of view of geochemical fractionation, Cr in soils occurs mainly in residual pools that are generally stable and not available [11].…”
