“…Yoon et al (2006) and Brandao et al (2018) have assessed the potential for phytoremediation with plant species growing on a polluted area and, noticed that the concentration of Pb was highest in the roots of plants; this study found higher Pb concentrations in the shoots compared to other metals. Reduction of the toxicity of heavy metals is the compartmentalization of metals in vacuoles strategy used by the plants (Ali et al, 2013;Brandao et al, 2018).…”

“…Some investigators reported that the inhibition of growth and reduction in xylem may be due to the accumulation of heavy metals in the walls and air canals which (comprises cells with large intercellular spaces that allow the air supply to underwater plant parts in the control area and make up the cortex and the pith) were destroyed and disappeared (Weryszko-Chmielewska and Chwil, 2005;Al-Saadi et al, 2013;Brandao et al, 2018).

This study was carried out to determine the heavy metal accumulation of Juncus rigidus Desfontaines, 1798 from three different regions of the Basrah Province in Southern of Iraq. Specifically, the concentrations of lead, nickel, and cadmium were determined in the roots, culms and leaves of the plant. The results indicated that the highest accumulation of the heavy metal was recorded in lead (Pb) 12.50± 3.58 mg kg-1 and then in nickel (< 0.30). The lowest value was recorded for cadmium (< 0.05). As well, lead concentrations in J. rigidus varied in different locations and parts of the plant from undetectable in control to 12.66, 19.33, and 9.80 mg kg-1 in leaves, culm, and roots respectively from Station 2, and 10.76, 12.66, and 9.50 mg kg-1 in Station 3. The values of translocation factor (TF), bioconcentration factor (BCF), and Biological Accumulation Coefficient (BAC) were greater than>1 used to the ability of J. rigidus for both phytoextraction and phytostabilization. The anatomical analysis showed that heavy metal accumulation in plant tissues led to a reduction in root and culm thickness; in polluted area it has been found that cortex and intercellular spaces in aerenchyma layers were deceased in size, whereas high pollution levels were observed in vascular bundles, which were smaller, and had increased sclerenchyma, as well as appeared more black or dark color compared to the specimens grown in the control area.

“…Several characteristics were observed including leaves size, color and root length. This characteristic have been used by several researchers to observe morphological changes in both aquatic plants as phytoremediation (Brandão et al, 2018;Sood et al, 2012). The sample was prepared dried at a temperature of 30 C and kept in a dry cabinet (MRC, Model: Dycd -100, UK) before examination under Tabletop SEM (Hitachi Model: TM3000, Japan) observation.…”

The potential of two different aquatic macrophytes, A. pinnata and L. minor to treat livestock wastewater through phytoremediation were investigated. The physiological includes the removal efficiency of Manganese (Mn) from livestock wastewater by AAS, morphological observation was performed under visual and SEM. RAPD analysis were applied to observe the DNA expression. It was observed that the removal efficiency of Mn, was higher in L. minor with 92% removal rate, while in A.pinnata RE was at 77% rate. A.pinnata exhibits symptoms of cell death by shrinking when exposed to livestock effluent as early as 24 hours but L.minor showed no changes. RAPD analysis showed that there are 19% of polymorphism in L.minor, in A.pinnata there is increase in band intensities. It can be concluded that L. minor performed better as a hyperaccumulator in livestock wastewater than A. pinnata which exhibits signs of cell death.

“…Disturbance in uptake and transport of mineral nutrition can decrease photosynthesis and dry weight of shoot and root (Ahmad et al 2011). Also, morphological changes occur in response to heavy metals in plants (Brandão et al 2018). But Herath et al (2013) reported variety Bg 352 of rice (Oryza sativa L.) increased the root dry weight from 50 to 100 mg Cd/kg, while Rossato et al (2012) reported the no alteration in the dry weight yield of Pluchea sagittalis Lam.…”

Potential of Mentha aquatica L., Eryngium caucasicum Trautv. and Froriepia subpinnata Ledeb. for phytoremediation of Cd-contaminated soil

et al. 2019

In three-pot experiments, the uptake and translocation potential of cadmium (Cd) by Mentha aquatica L., Eryngium caucasicum Trautv. and Froriepia subpinnata Ledeb. was evaluated in different Cd concentrations including 0 (control), 5, 10, 15 and 20 mg Cd kg-1 dried soil. Plants accumulated Cd in their roots and shoots without toxicity symptoms. Enhancement of Cd concentration greatly decreased plant biomass. Bioconcentration factor (BCF) and translocation factor (TF) in F. subpinnata were higher than one that indicated higher efficiency of this plant for phytoextraction of Cd from soil. The efficiency of plants in uptake and translocation of Cd depends on species, biomass production, Cd concentration in biomass and soil. Cadmium concentration in M. aquatica root was higher than shoot. Mentha aquatica with higher BCF and lower TF than one can be suitable for phytostabilization of Cd. Also, uptake index and BCF for M. aquatica showed better phytoremediation potential in comparison with E. caucasicum and F. subpinnata.
