“…J-172 and Salix babylonica L. (Chen et al 2012). Kissoon et al (2010) also found the flooding significantly increased metal (Cu, Fe, and Mn) uptake by Rumex Crispus L. It was suggested that iron plaque formed on root surface in flooding conditions reduced the uptake of metals by plants because of its iron hydroxide functional groups (Batty et al 2000;Liu et al 2011a). The increase in HMs in the roots was partly due to the retention effect of HMs by iron plaques on the root surface.…”

As a metal immobilizer, biochar can be used to remediate contaminated soil. Biochar’s effect on the phytoremediation process in flooded conditions under a scenario of increasing flooding frequency as global climate change is not well understood. This study investigated bamboo biochar (BBC) effects on growth and metal accumulation of Salix in multi-metal contaminated soil under non-flooded versus flooded conditions. Salix cuttings were cultivated in pots with severely contaminated soil by Cd and Zn, for 120 days, with four treatments including non-flooded treatment, flooded treatment, non-flooded with 3% BBC application (BBC/soil, w/w), and flooded with 3% BBC addition. BBC, flooding, and BBC× flooding significantly decreased the bioavailability of metals in soils (P < 0.05). The BBC addition markedly stimulated Cd concentration in leaves under non-flooded (94.20%) and flooded conditions (32.73%) but showed little effect on roots. The BBC significantly boosted Cd and Zn transport from roots to aboveground parts by 68.85% and 102.27% compared with no BBC amendment under non-flooded treatment, while showing insignificant changes under flooded treatment. Although the plant biomass was little affected, BBC significantly increased Cd and Zn accumulation in the whole plant by 52.53% and 28.52% under non-flooded while showing an insignificant impact under flooded conditions. Taken together, BBC enhanced the phytoremediation efficiency of Salix to Cd and Zn in severely polluted non-flooded soil, while flooding offset this effect. The results indicated the effects of BBC varied under different soil moisture, which should be considered in the biochar-assisted phytoremediation to variable and complex environments.

“…This has predefined the choice of methods to atomic absorption spectrometry (AAS) and ICP-AES and ICP-MS. Recently, however, many less studied elements such as REEs and platinum metals are increasingly used in different technological processes and present potential ecological problems on the one hand, though, on the other hand, some of them may be beneficial to plant growth (39,40) or correlate with other elements in the plant (1, 2). Thus, the necessity to determine as many elements as possible in different concentration intervals demands the use of methods and/or a combination of methods permitting multielement analysis with high accuracy and precision.…”

The study of the ionome (ionomics) is defined as quantitative and simultaneous measurement of the element composition of living organisms and changes in this composition in response to physiological stimuli, development stage, and genetic modifications (Salt et al., Ann. Rev. Plant Biol., Vol. 59, 2008). The necessity of understanding the regulation processes of elements in the organisms demands determination of many elements in the organism, tissue, and cell (Baxter, Plant Biol., Vol. 12, 2009) . A prospect for ionomics is environmental pollution where great variety of conditions and pollutants exist resulting in concentration and interelemental changes in the plant ionome. The capabilities of and problems with several multielement analytical techniques, including instrumental neutron activation analysis (INAA), X-ray fluorescence, inductively coupled plasma-atomic emission spectrometry (ICP-AES), inductively coupled plasma-mass spectrometry (ICP-MS), and atomic absorption spectrometry (AAS), which are adequate and most promising in ionomic and environmental studies of plants, are reviewed. References are confined mainly to the last 10-15 years. Information about concentrations, roles, binding forms, and pollution sources of the elements and comparison between methods with respect to limits of detection, determined elements, interferences, and economic considerations are tabulated. Some combinations of instrumental techniques supplementing each other are highly valued, namely, ICP-MS and ICP-AES and INAA and AAS or ICP-AES.

“…For instance, metal sorption on the organic matter accumulated in the rhizosphere and on the Fe/Mn root plaque contributes to higher metal accumulation in the macrophyte rhizosphere (McCabe et al, 2001;Otte et al, 2004). However, through root exudation and acidification, metals can be mobilized for uptake (Kissoon et al, 2010). Consequently, wetland plants are frequently more exposed to higher metal concentrations than dryland plants: e.g.…”

“…Thus, rooted macrophytes may have been exposed to higher Cu concentrations than most dryland plants over their evolution. Kissoon et al (2010) reported for example greater Cu concentrations under wetland compared to dryland conditions in the whole plant for Rumex crispus. Consequently it is commonly admitted that selection may have shaped a constitutive TE tolerance for macrophytes (Ye et al, 1997a(Ye et al, ,b, 2003McCabe et al, 2001;Matthews et al, 2004a,b;2005;Kissoon et al, 2010), even if for some species such…”

Intra-specific variability of root biomass production (RP) of six rooted macrophytes, i.e. Juncus effusus, Phragmites australis, Schoenoplectus lacustris, Typha latifolia, Phalaris arundinacea, and Iris pseudacorus grown from clones, in response to Cu exposure was investigated. Root biomass production varied widely for all these macrophytes in control conditions (0.08 μM) according to the sampling site. Root biomass production of T. latifolia and I. pseudacorus in the 2.5-25 μM Cu range depended on the sampling location but not on the Cu dose in the growth medium. For P. australis, J. effusus, S. lacustris, and P. arundinacea, an intra-specific variability of RP depending on both the sampling location and the Cu-dose was evidenced. This intra-specific variability of RP depending on the sampling location and of Cu-tolerance for these last four species suggests that Cu constitutive tolerance for all rooted macrophytes is not a species-wide trait but it exhibits variability for some species.
