“…Soil from a large area near the river Timok was contaminated by flotation tailing composed mainly of pyrite (FeS 2 ). Consequently vegetation in this area suffered abiotic stress induced by a low pH, high content of copper and lead, deficiency of soil organic matter and severe deficiency of the available mineral nutrients [1].…”

Background and Purpose: Mycorrhizal fungi are of high importance for functioning of forest ecosystems and they could be used as indicators of environmental stress. The aim of this research was to analyze ectomycorrhizal community structure and to determine root colonization rate with ectomycorrhizal, arbuscular mycorrhizal and endophytic fungi of poplars growing on pyrite tailings contaminated site near the river Timok (Eastern Serbia). Materials and Methods: Identification of ectomycorrhizal types was performed by combining morphological and anatomical characterization of ectomycorrhizae with molecular identification approach, based on sequencing of the nuclear ITS rRNA region. Also, colonization of poplar roots with ectomycorrhizal, arbuscular mycorrhizal and dark septated endophytic fungi were analysed with intersection method. Results and Conclusions: Physico-chemical analyses of soil from studied site showed unfavourable water properties of soil, relatively low pH and high content of heavy metals (copper and zinc). In investigated samples only four different ectomycorrhizal fungi were found. To the species level were identified Thelephora terrestris and Tomentella ellisi, while two types remained unidentified. Type Thelephora terrestris made up 89% of all ectomycorrhizal roots on studied site. Consequently total values of Species richness index and Shannon-Weaver diversity index were 0.80 and 0.43, respectively. No structures of arbuscular mycorrhizal fungi were recorded. Unfavourable environmental conditions prevailing on investigated site caused decrease of ectomycorrhizal types diversity. Our findings point out that mycorrhyzal fungal community could be used as an appropriate indicator of environmental changes.

“…In order to achieve a more critical test for the evaluation of white poplar genotypes for use in phytoremediation projects, we used modified medium with the intention to increase the bioavailability of lead by increasing its mobility both by lowering the pH and using citric acid as a chelating agent (Yang et al 2006). Beside general benefits in lead testing in vitro, test on acidic media could be especially important for situations where heavy metal pollution is accompanied by acidification of soil, such as soil pollution after accidents in mining facilities (Antonijević and Marić 2008).…”

This study evaluates in vitro tolerance of white poplar genotypes to the presence of lead in an acidic rooting medium. Lead was supplemented in form of Pb(NO3)2, in the following concentrations: 0 M (Control), 10-6 M, 10-5 M, 10-4 M and 10-3 M. After four weeks of cultivation, the following characters were measured: number of roots, the length of the longest root, the shoot height, dry root mass and dry shoot mass, and parameters related to photosynthetic pigments: content of chlorophyll a, b, a+b, and of carotenoids in fresh mass, as well as chlorophyll a/b ratio. For further statistical analysis, tolerance indices by Turner and Marshal (TI) were calculated for each measured character. The strongest inhibitory effect was achieved on the medium with 10-4 M Pb(NO3)2, but the best differentiation between genotypes was achieved on the medium with 10-5 M Pb(NO3)2. The highest tolerance indices for the length of the longest root and shoot height had genotypes L-12 and LBM, and for root and shoot dry mass genotypes LCM and L-12. There were no significant differences between genotypes in tolerance indices by any of the examined photosynthetic parameters. The obtained results suggest that both low pH and the presence of citric acid as chelating agent improved evaluation of lead tolerance in comparison with the results obtained on media with standard pH and without citric acid in similar studies. In vitro tests on acidic medium with citric acid can efficiently differentiate examined genotypes for lead tolerance, which could be important for their use in phytoextraction projects, especially on acidic soils.

“…According to World Health Organization (WHO) the metals of most immediate concern are chromium, copper, zinc, iron, cadmium and lead [5]. Although in nature cadmium occurs in trace amounts and constitutes only 0.00005% of the crust of the earth, it has been listed by UNEP/WHO as substance dangerous to the environment because along with such metals as lead, mercury, copper, zinc, chromium, tin and silver, it poses a risk of disturbing the balance in ecosystems [6][7]. One characteristic feature of cadmium is its high stability in environment.…”

This study explored the adsorption behavior of Cd(II) ions on Junipers Procera Roots powder from aqueous solutions. The effect of various operational parameters such as pH, contact time, initial adsorbate concentration, dosage of adsorbent and temperature on adsorption of Cd(II) ions were investigated using batch adsorption experiments. The optimum pH for Cd(II) adsorption was found to be 7.0. The suitability of Langmuir and Freundlich adsorption models to the equilibrium data was investigated. The adsorption was well described by the Freundlich isotherm model indicating the presence of heterogeneous sites for Cd(II) adsorption. Thermodynamic parameters showed that the adsorption of Cd(II) on Junipers Procera Roots was feasible, spontaneous and exothermic.
