“…In contaminated sites, increasing Fe concentration in shoots are desirable as a nutrient amendment for phytoextraction approaches for maintaining plant health by increasing the amounts of chlorophyll (Keller and Hammer, 2004). On the other hand there was a decreasing tendency of Fe in shoots with increasing Pb rates probably due to Fe and Pb competition to the biding sites in the root cell wall (January, 2008). In such case, EDTA can amend Pb-induced Fe deficiency in the plants by increasing Fe in shoot during the Pb phytoextraction process.…”

A greenhouse study was conducted to evaluate the effects of ethylenediamine tetraacetic acid (EDTA) addition to soils on the lead (Pb) phytoextraction potential of jack beans (Canavalia ensiformis L.). In a pot experimentSoil samples (dystrophic Rhodic Hapludox) were treated with six Pb rates (0, 100, 200, 350, 1,200, and 2,400 mg kg-1 soil) applied as Pb(NO3)2 without and with EDTA application (0 and 0.5 g kg-1, respectively). Lead, Cl-, NO3-, NH4+, SO4(2-), H2PO4-, Zn2+, Cu2+, Fe3+, Al3+, Ca2+, Mg2+, K+ and DOC (dissolved organic carbon) concentrations obtained in a saturation soil extract (soil:water ratio of 1:0.3) were used for Pb speciation by means of the software Visual-Minteq 2.30. Soil Pb-availability was assessed with Diethylene triamine pentaacetic acid (DTPA) extraction. EDTA treated soils showed higher Pb (as PbEDTA2-), and Fe (as FeEDTA-) concentrations in soil solution leading to higher uptake of these elements by the jack bean. On the other hand, it decreased the concentration of stable complexes as Pb-DOC and Fe-DOC. EDTA also induced better nutrition to plants building up the concentration of non target metals (Ca, K, Mg, Zn, Cu, Fe and Mn) in shoots. Shoot dry matter yield remained constant even at the highest Pb rates after EDTA treatment. Jack bean can be considered as a potential Pb-phytoextractor. In addition, the DTPA solution was effective to assess Pb availability to the plants at all applied Pb rates.

Ten Indian mustard (Brassica juncea L.) genotypes were screened for their phytoremediation potential for arsenic (As) contaminated water under laboratory-controlled conditions. The genotypes were grown in a hydroponic chamber for 20 days in 250-mL beakers containing As-contaminated water. During plant development, changes in plant growth, biomass, and total As were evaluated. Of the 10 genotypes (Pusa Agrani, BTO, Pusa Kranti, Pusa Bahar, Pusa Bold, Pusa Basant, Pusa Jai Kisan, Arka Vardhan, Varuna, and Vaibhav) Pusa Jai Kisan was the most effective in phytoremediating Ascontaminated water under hydroponic conditions. This will provide new information for Indian mustard genotypes for phytoremediating As-contaminated soils.

“…The results is so, possibly due to the presence of the additional metal elements (Mn, Cd, and Ni) in E1 media compared to E2 with just Zn and E3 which lack of any. The presence of trace element in the growing media will definitely promote rapid production of leaves as it also allowed active photosynthesis to occur [9]. Additionally, E2 media also contain K which is an essential nutrient for plants necessary for osmotic balance and ion exchange process in plant tissues.…”

“…Among the two exposed media, E1 promoted better growth. This is probably due to the abundant of additional elements such as Mn, Cd, and Ni which are needed in trace amount for plant growth [9]. number of leaves will increase over time.…”

Heavy metals contaminations are among the most hazardous environmental pollution due to its ability to resist disintegration in the natural ecosystem. Thus, they pose risk to living organisms as they are persistent in the environment. Reports on the accumulations of heavy metal in edible plants had alarmed many parties that the general public has become more aware on the seriousness of this issue. Bioaccumulation within the food chain poses potential risks of toxicity effects. Thus, it is crucial to conduct appropriate study to analyze the pathway of the heavy metal elements as a measure to understand the behavior of the heavy metal elements. The aim of this paper is to investigate heavy metal accumulation in plant tissue, particularly the leave, stem and root. Ipomoea reptans and Helianthus annuus were selected as the experimental plant species in the study. Spent dry cell or batteries were utilized as the source of heavy metal contamination of which batteries are commonly discarded in the municipal solid waste stream. Results indicated that the accumulation of heavy metals in the two plants were low and below the limit of European Union Standard for edible plants. However, heavy metal in alkaline batteries exposure was found to promote the growth of longer root in both plants as compared to carbon-zinc batteries and the control. Yet, the accumulation of heavy metal in the plants tissues in this study were only monitored for the period based on the maturation of the plants, longer exposure may result with different outcome, that further investigation is deemed necessary.
