“…Copper at a concentration of 0.05 mM, manganese at 0.80 mM, and zinc at 0.12 mM showed a negative effect on shoot growth (number of shoots per explant and shoot length) in Ailanthus altissima, considered a fast-growing and contamina tion-resistant species (Gatti 2008). Zinc was found toxic in aspen (Populus tremula x tremuloides) cultures at 0.5 mM concentra tion, while lead at the same concentration did not show toxic effects and was accumu lated at 3500 μg per g of biomass (Kalisová-Spirochová et al 2003). In vitro studies were also developed to investigate the effects of high concentrations of zinc and copper on the biosynthesis and accumulation of poly amine in Populus alba (Franchin et al 2007).…”

Soil contamination by heavy metals is among the most serious danger for the environment, and new methods for its containment and removal are claimed, in particular for agricultural soils. Phytoremediation is an emerging, potentially effective technology applicable to restoration of contaminated soils and waters. Besides hyperaccumulator herbaceous plants, several woody species are now considered of interest to this aim. Many woody plants are fast growing, have deep roots, produce abundant biomass, are easy to harvest, and several species revealed some capacity to tolerate and accumulate heavy metals. Biotechnologies are now available for investigating this potential and enlarge the possibilities of exploitation of trees for remediation. The use of in vitro cultures, the role of bacteria and mychorrhizas, the powerful tool of genetic engineering, are some of the aspects focused in this paper that open prospects of global relevance for a better understanding of the processes related to the uptake of heavy metals by woody plants. In recent years significant progress has been made in identifying native plants and developing genetically modified tree plants for the remediation of heavy-metal polluted environment. Despite the intensive research developed in the last years, few field trials demonstrated the feasibility of the approach described, therefore much efforts should be addressed to this goal

“…According to Huang et al (1997), in most of the contaminated soils they examined, lead content in soil solution amounted to less than 0.1% of the total lead content in the soil. Also, Kališova-Špirochova et al (2003) found that in a highly polluted industrial area, where contaminated soil contained 16000 mg•kg -1 of Pb 2+ , the content of lead in water leachate was just 0.45 mg.l -1 (i.e. 5.49 μM).…”

“…Developmental and molecular data obtained by Castiglione et al (2007) in white poplar support the use of in vitro techniques in the study of heavy metal stress responses. Tolerance of white poplars to heavy metals, including lead, has been tested in controlled conditions, and differences among genotypes were found (Kališova-Špirochova et al 2003, Bojarczuk 2004, Bittsanszky et al 2005, Katanic et al 2007, 2008, di Lonardo et al 2011. Nowadays, these tests include the use of media that increase bioavailability and mobility of heavy metals by lowering pH and the use of chelators (Vuksanović et al 2017a).…”

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.

“…Arsenic was higher in roots than in leaves for corn [7] but higher in leaves with Chinese Brake ferns [43]. Corn gave a better heavy metal uptake when compared to sunflower although both gave significant successes as observed by Mathew [7] and Spirochova et al [44].…”

This review presents the justification of research into heavy metals and clean-up technologies with particular emphasis on phytoremediation of heavy metals contaminated soils. The generating sectors and heavy metal contaminant contributors are reviewed alongside likely types. The new paradigm by researchers in response to negative impacts of various clean-up methodologies has been discussed. This work reports limitations and prospects of phytoremediation in view of the future direction and reviewed issues with bioavaliability, mobility, and response by plants to heavy metals in their environment. It reviews various plants used in phytoremediation of heavy metals and level of success recorded by teeming researchers. Diverse options available for optimization of this relatively novel technique to enhance performance have been elaborated. Suggestions for responsible abandonment of emitting sites and facilities, safety issues and appropriate disposal and management methods for plants used in this technology have been documented.
