“…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].…”

“…5). It was documented that total concentration of trace metals in soil or some soil properties could be related to plant metal concentrations [25,29] but other studies found no relationships [18][19]21]. Correlation analysis did not confirm positive relationships between Hg, Cr and Ni concentrations in the roots/aboveground parts of nettle and their total concentrations in soil.…”

“…Mobility of Hg, Cr and Ni in soils and their transfer from soil to plants is a complex function of several variables, such as geochemical fractionation of metals among soil components, physico-chemical and mineralogical characteristics of soil substrates and plant species [12][13][19][20][21][22][23][24][25][26]. Total concentrations of trace metals are not of prime importance for assessing the ecological and health risks of contaminated soils.…”

The former mercury ore deposit of Merník in Eastern Slovakia was selected for the investigation of the environmental availability of mercury (Hg), chromium (Cr) and nickel (Ni) in mine soils. Singlestep extractions with four chemical agents (deionised water, ethylenediaminetetraacetic (EDTA), acetic (CH 3 COOH) and hydrochloric (HCl) acid solutions) and chemical analysis of the common nettle (Urtica dioica) were used to determine the availability of the three metals. Regardless of the type of extraction, the soluble ratios of metals in mine soils increased in the order of Hg≤CrCH 3 COOH ≈ EDTA>˃H 2 O. The total or extractable metal concentrations in soil did not correlate with their concentrations in aerial parts of the common nettle, however, its ability to accumulate these trace metals in roots and aerial parts copied the results of extraction tests, i.e. Hg≤Cr

Wastewater recycling technologies have been widely used in tanneries to reduce environmental impacts. However, only a few recycling methods have been developed for vegetable tanning processes due to limited knowledge of their wastewaters. In this study, the structures of the polyphenols in the larch tanning wastewater (LTW) and commercial larch tannin (CLT) were characterized with spectrographic and chromatographic analysis. Structures of these polyphenols were illustrated accordingly; their collagen reaction abilities were then tested with thermal analysis and visualized with a molecular docking software. Results showed that polyphenols in LTW and CLT were all procyanidins. However, average molecular weight of the polyphenols in LTW was 1104Da, in contrast to an obviously higher value for the CLT sample (3334Da). Meanwhile, the LTW presented obvious lower reactivity in the collagen-polyphenol reaction, including lower thermal stabilities and docking energies, fewer hydrogen bonds, and lower interaction energies. These results provide a hint for vegetable tanning wastewater recycling: because of these structural differences, reactivity of the polyphenols in wastewater are lower than the ones in commercial tannins. Therefore, before the recycling processes, polyphenols must be chemically modified in accordance with these structural differences.

The objective of this research was to evaluate trends and relationships of energy and toxic elements accumulation in A-horizon (the depth of 0–5 cm) of soils and in selected plants of the hemioligotrophic (Dystric Cambisols) and oligotrophic (Skeletic-Rustic Podzols) spruce ecosystems situated along transect (750–1110 m a.s.l.) in the NP Slovenský raj (Eastern Slovakia). The results showed that EU limit values of risk elements in agricultural soils were exceeded for Cu and Cd at the altitude of 750–760 m a.s.l., and in case of Cd also above 1000 m a.s.l. Relationship between energy and toxic elements in soils revealed that with an increasing amount of energy, contents of Zn and Cu significantly declined with altitude (r > –0.5 or r > –0.9). The background value of Cu was exceeded in all plants, that of Zn for Dryopteris filix-mas and Rubus idaeus. Furthermore, excessive accumulation of Cd was revealed by all plants. Cu contents in soils were dominant in determining Cu uptake for Vaccinium myrtillus (r > 0.5); Zn and Cd for V. myrtillus (r > 0.6), D. filix-mas (r > 0.5 or r > 0.8) and Fagus sylvatica (r > –0.8 or r > –0.5); Zn also for R. idaeus species (r > 0.4). The soil-plant transfer coefficients higher than 1 hinted R. idaeus on the plots at the altitude of 960 m a.s.l. (Cd 1.1, Cu 1.2, Zn 3.1), which appears as an excellent native indicator of forest ecosystem contamination.
