“…Contents of Pb in our experiments varied from 0.36 mg/kg to 1.07 mg/kg. In other experiments results also ranged in very broad limits: from 0.68 [ 43] to 13 mg/kg and more [44]. Concentration of Ni in willow leaves in our experiments was 1-2 mg/kg.…”

Willow is a low-maintenance crop that has potential for energy production and enhancing the local environment. The area of commercial plantations of willow in Europe is mostly concentrated in Sweden, with more than 20 000 ha. Willow trees are used not only for energy production, but also for reclamation of polluted soils because a plantation may grow for 20–25 years, with a three-year period of harvesting. Our research covers issues of reclamation of soils contaminated by radionuclides and heavy metals, and decreasing of eutrophication of water ecosystems with using willow plantations. The field studies of phytoremediation of soil contaminated by 137Cs by willow plants were conducted in eastern Belarus, in the area where agricultural activity was banned after Chernobyl disaster. This region is heavily polluted with 137Cs (from 185 to 555 kBq/m2) and heavy metals. The transferring factors of accumulated 137Cs and heavy metals from the soil to willow biomass were determined. The field experiments showed that willow does not accumulate actively Cd and Pb, but it accumulates Zn, Cu and Mn intensively. The potassium application decreases the accumulation of 137Cs in willow biomass and increases accumulation of Cu, Zn and Mn, but has no influence on accumulation of Cd and Pb. Our results confirmed that soils polluted with radionuclide and heavy metals could be used for willow cultivation as energy crop, if adequate management is applied. The different potential of the willow species concerning heavy metals accumulation was also established. The yield of willow biomass on polluted soils achieved 11.5–12.8 DMg ha–1 per year, depending on variety, that is competitive with the ordinary yield of willow on mineral fertile soils. Willow plantations also may be used for accumulations of nutrients like nitrogen and phosphorus in watersheds. It enables to decrease impact for water ecosystems and to control eutrophication.

“…They cannot be degraded biologically and are difficult to clean up. A clean and effective method of removing heavy metals from soil, called phytoremediation, has been widely studied [2]. Plants are essential components in ecosystems because they transfer elements from the abiotic environment to the biotic one [3].…”

Salix matsudana Koidz was exposed to different concentrations of Cd (0, 10, 50, and 100 µmol/L) to study the effects of Cd on mineral metabolism and antioxidant enzyme activities. The results showed that plant height and root length were inhibited by 50 and 100 µmol/L Cd, except the one under 10 µmol/L Cd treatment. The Cd content accumulated in different organs of S. matsudana, gradually increasing with increased Cd concentrations and prolonged treatment times. The root was the main organ for absorbing and accumulating Cd. Cd inhibited the accumulation of Fe, Zn, Mn, and Cu. In addition, the activities of antioxidant enzymes and the contents of reactive oxygen species were also changed by different concentrations of Cd. The results obtained here can provide scientific and objective data for the use of S. matsudana in the remediation of Cd-contaminated soil.

“…The above list should be supplemented with a number of poplar and willow species that act as cadmium and/or zinc accumulators (Baltrėnas, Čepanko, 2009;Borišev et al, 2009;De Maria et al, 2011;Ermakov et al, 2015a;Markovskaya et al, 2015). In the area of the Unal tailings pond we discovered a new endemic metal accumulating plant species, Cladochaeta candidissima (M.…”
