“…A similar relation has been noted by Symeonidis and Karataglis (Symeonidis and Karataglis 1992) in the studies of interactions between the metals in Holcus lanatus L. The antagonistic effect of Zn on Pb was also observed in Faba vulgaris Moench (Bystrická et al 2013). Reduction of lead content to 0.61 ± 0.17 μg/g was due to the presence of zinc in an amount of 80 μg/g.…”

Abstract:The article presents the results of research which describes antagonism between Pb-Zn in selected plant species from the area of Czestochowa -Mirow district (north-western part of the Czestochowa Upland). There were analyzed changes in the ratio of Pb/Zn in different organs of the tested plants as a function of the Zn content changes. The content of metals in the plants and the soil was determined using atomic absorption spectrophotometry AAS. In all organs of the plants there was observed antagonistic decrease of Pb uptake and accumulation, resulting from the increase in the concentration Zn.Antagonism between Zn and Pb in roots of the tested plants occurred at Zn content of 200-600 μg/g. In turn, antagonism in stems and fl owers occurred at lower contents of zinc (100-180 μg/g). In leaves, antagonism between Pb and Zn occurred when Zn was present at the level of 300-800 μg/g.Ex defi nition of the analyses confi rm the presence of antagonism of lead with regard to high levels of Zn. The study also confi rmed that the degree of antagonism depends on the plant species.

“…Several studies have been carried out on the defense mechanism of plants under oxidative stress (Mizuno et al 1988;Hegedu¨s et al 2001;Lee et al 2001;Cao et al 2004;Wang et al 2004a,b). The coexisting heavy metals at multi-elemental contaminated sites have synergistic, additive or antagonistic effects in the plants (Rosko and Rachlin 1977;MartinPrevel et al 1987;Symeonidis and Karataglis 1992;Siedlecka 1995;Krupa et al 2002). The knowledge of detoxification mechanism is of critical importance from a practical standpoint of optimizing the mechanism of phytoremediation through improvement in cellular defense mechanism to combat heavy metal stress in hyperaccumulator plants (Aravind and Prasad 2005).…”

The present study investigates the interactive mechanism involved during the uptake of heavy metals and stress tolerance in Brassica juncea L. seedlings under the influence of Mn(II) in binary combinations with Cr(VI), Ni(II), Co(II) and Cu(II) in terms of changes in antioxidative enzymes-superoxide dismutase (SOD), guaiacol peroxidase (GPX), catalase (CAT), ascorbate peroxidase (APX) and glutathione reductase (GR). The order of uptake of heavy metals by the seedlings in single metal solutions was observed to be, Mn CuCo CrNi. As revealed by multiple regression and path analysis, manganese (Mn) in binary combination with other heavy metals mutually decreased the uptake of each other. Mn and other metals were antagonistic to each other for the activities of SOD, GPX, APX and GR, and decreased the effect of each other through interaction, whereas antagonism between these metals increased the activity of CAT.

“…Combination of Pb and Zn supplied during treatment was reported to increase the uptake of Zn, but decrease the uptake of Pb (Symeonidis & Karataglis, 1992), while our current study found Pb combined with Zn in the nutrient solution insignificantly influenced the uptake of Zn, but increased the uptake of Pb. The presence of some specific buffers (e.g.…”

“…The effects of Cu and Pb in our study had a synergistic effect on the growth of N. caerulescens according to the classification of plant responses to metals in the growing medium (Symeonidis & Karataglis, 1992). The significant reduction in shoot dry mass in the treatments involving Cu, and the significant reduction after treatment with Zn + Pb, showed that Cu markedly inhibited plant growth and that the Pb levels imposed were also causing.…”

“…Uptake and accumulation of Cu in plants was independent of the level of Zn exposure, but an excess of Cu in the solution culture reduced Zn in plants (Reboredo, 1994). A combination of Pb and Zn supplied during treatment was reported to increase the uptake of Zn, but decrease the uptake of Pb (Symeonidis & Karataglis, 1992). The uptake of Zn in N. caerulescens was reduced by 9%, 87% and 84% when 5 ppm Pb, 1 ppm Cu or 2 ppm Cu was added to the nutrient solution, respectively (Walker & Bernal, 2004).…”

Phytoextraction of zinc by the hyperaccumulator Noccaea caerulescens: accumulation, distribution and multi-element interactions

Phytoextraction involves the removal of heavy metals from contaminated sites using hyperaccumulators such as Noccaea caerulescens F.K.Meyer (formerly Thlaspi caerulescens) which is a well-known Zn hyperaccumulator and a model species for hyperaccumulator studies.This PhD thesis investigates the zinc response of the hyperaccumulator in terms of accumulation, distribution and multi-element interactions. The impact of Zn, Pb and Cu on the growth, Zn accumulation and distribution, and interaction between the metals and between the metals and other plant nutrients were examined in soution culture to provide insights into the physiological and biochemical mechanisms of metal hyperaccumulation and detoxification.Noccaea caerulescens were treated with a range of Zn concentrations to investigate uptake, tolerance and distribution of Zn, and these were compared with the responses in a related nonhyperaccumulator, Thlaspi arvense. Noccaea caerulescens showed a high Zn requirement for growth and a higher Zn accumulation and tolerance, with in excess of 2.5 % Zn in the shoot dry mass occurring without visible toxicity symptoms. Thlaspi arvense displayed Zn toxicity symptoms within two weeks of comparable Zn treatment. Increasing shoot Zn concentrations in N.caerulescens reduced Ca and P concentrations by up to 50% and 35%, respectively. Scanning electron microscopy with energy-dispersive X-ray (SEM-EDS) showed that Zn-containing crystals were abundant in leaf epidermal cells and the cortex of the roots during the later growth phase of N. caerulescens.The impact of Pb and Cu on Zn phytoextraction in N. caerulescens was investigated and these metals in solution were found to inhibit both growth and Zn accumulation when present in combination with Zn. Plants were more sensitive to Cu than Pb with Cu being more readily transported to the shoots while almost all Pb was retained in the roots. Concentrations of other essential nutrients such as Ca, Mg, P, S, Fe, and K were decreased in shoots but increased in roots when there was a prolonged period of metal exposure. Higher levels of Zn accumulation decreased the concentrations of Ca, Mg, S and Fe in shoots. Sub-cellular elemental localization analysis using SEM-EDS revealed that Zn accumulated primarily inside the vacuoles of leaf epidermal cells. Znrich crystals were observed in the SEM freeze-dried leaf samples of the control and the Zn plus Pb treatment after extended exposure, but no crystals were found in the cryo-SEM leaf samples.Copper and Pb were not detected in the Zn-rich crystals of the freeze-dried samples or the cryo-SEM samples.ii A fluorescent probe technique was developed and applied to investigate the distribution of Zn ion in fresh plant tissues. Noccaea caerulescens was found to have not only a high capacity for Zn accumulation, but also a high tolerance to Pb. Both these characteristics were more prominent in younger plants. Zinc in combination with Pb had less impact on plant growth than Zn alone. In this thesis, a number of novel techniques were succe...
