“…In our experiment, the presence of Cu affected the concentration of the macroelements, Ca, Mg, N and P. An excess of Cu inhibits the activity of phosphatase, thereby diminishing the availability of P (Tyler, 1976). Lin and Wu (1994) found that in Lotus purshianus, an excess of Cu reduced the concentration of P in both root and leaf tissues. Cu-Ca interactions are highly complex and apparently cross-linked with the range of pH in the growth media (Kabata-Pendias and Pendias, 2001), and Mg is replaced in the chlorophyll by Cu (Küpper et al, 2002).…”

Plants have gained importance in situ bioremediation of heavy metals. In the present study, different concentrations of zinc (Zn 2? ) (0.5, 5, 10, 15, 20 mg/l) and lead (Pb 2? ) (1, 2, 4, 6, 8 mg/l) were used to evaluate metal tolerance level of Lemna minor. L.minor were exposed to metals for 4 days and tested for its dry to fresh weight ratio (DW/FW), photosynthetic pigments production and protein content. The oxidative damage was detected by measuring catalase activity. L.minor showed tolerance against Zn and Pb 2? toxicity up to the concentration of 10 and 4 mg/l, respectively. Hence, the metal tolerant property of this plant shall be exploited for bioremediation of Zinc and Lead in polluted water. Further, the detailed and wide range of heavy metal toxicity studies should be done to reveal the possible use of this plant on large scale bioremediation purpose.

“…It was evident that Cu stress was much more critical for K and Mn nutrition than Cd stress; conversely, Cd stress showed more deleterious effects on Zn content in comparison with Cu. A number of reports also suggested a strong reduction of Mn uptake as a common manifestation of Cu phytotoxicity (Lidon and Henriques 1992;Lin and Wu 1994), which is not necessarily the case for Cd (Kabata-Pendias, 2011); likewise, Cd similarity with Zn is considered as a recurrent cause of its phytotoxicity (Verbruggen et al 2009). Combined effects of metals on plant mineral nutrition have received little attention from researchers.…”

Heavy metals' frequent occurrence and toxicity caused considerable concerns in assessing the interactive effects of metals on exposed plants. Therefore, a hydroponic study was conducted to assess the growth response and physio-chemical changes in Brassica napus plants under single and combined stress of two environmentally alarming metals (Cd and Cu). Results showed that 15-day metal exposure to different metal concentrations (0, 50, 200 lM) significantly enhanced Cd accumulation, while lesser extent of Cu was observed in plant tissues. Nonetheless, Cu caused more pronounced oxidative damages and plant growth retardation. Both metals showed similar trend of changes in mineral composition, although Cu proved more damaging effect on K and Mn contents, and Cd on Zn contents. In combined treatments, Cd stimulated Cu uptake, notably at low concentration, while its own uptake was restricted by the presence of Cu. At either level of concentration, combined stress of these metals exacerbated plant growth inhibition and caused further oxidative damages compared to their individual stress. However, metals synergistic effects occurred only in conditions where Cu uptake was enhanced by Cd. A greater synergistic effect was observed in sensitive cultivar Zheda 622 as compared to the tolerant cultivar ZS 758. As to mineral composition, no metals synergistic effects were noted. This study highlighted the ecotoxicological significance of Cd-led Cu uptake in B. napus, which was assumed to drive metals' synergistic toxicity, and showed that the relationship between Cd-led Cu uptake and plant growth responses could vary with respect to cultivar.
