“…This is due to the ability of plants to uptake essential elements compared to non-essential elements also plants may develop tolerance strategies that reduce their uptake and accumulation (Saha et al, 2015;Sarathambal et al, 2017;Sung, Lee and Munster, 2015). Plants which are possessing < 1 for TF and BCF values are considered to be unsuitable for phytoextraction process (Romanova, Shuvaeva and Belchenko, 2016;Romero-Hernández et al, 2017). Results indicate that the root parts of the plant possess high concentration of metal ions which indicates a higher accumulation of ions to protect photosynthetic tissue in the above ground parts (Saha, Banerjee and Sarkar, 2015;Salama, Al Watban and Al-Fughom, 2011).…”

The present study aimed to investigate the bioaccumulation of heavy metals from the effluent of battery industry by an aquatic plant, Bacopa monnieri. Experiment was carried for 25 days and heavy metal concentrations were analyzed in plant parts (roots and shoots), soil and effluent using atomic absorption spectroscopy (AAS) for 5 days each. Parameters such as Translocation Factor (TF), Bioconcentration Factor (BCF) and Transposition Factor (TrF) were calculated to analyze heavy metal interaction between plant, soil and effluents. Zn and Mg were found to be high in TF, BCF and TrF, but Cr had a TF value higher than Zn as it translocates high amount of ions to plant parts. TrF values of contaminants increased constantly in the following order: Mg > Zn > Cd > Pb > Cr. TF and BCF values were not > 1 for toxic metals (Pb, Cr and Cd). B. Monnieri can be used as a phytoextractor in removing contaminants from aquatic bodies.

This study presents the results of a coupled electrocoagulation-phytoremediation treatment for the reduction of copper, cadmium, lead, and zinc, present in aqueous solution. The electrocoagulation was carried out in a batch reactor using aluminum electrodes in parallel arrangement; the optimal conditions were current density of 8 mA/cm 2 and operating time of 180 minutes. For phytoremediation the macrophytes, Typha latifolia L., were used during seven days of treatment. The results indicated that the coupled treatment reduced metal concentrations by 99.2% Cu, 81.3% Cd, and 99.4% Pb, while Zn increased due to the natural concentrations of the plant used.

“…Metal uptake (MU), translocation/transfer factor (TF), bioconcentration factor (BCF), Percent metal uptake (% MU), Removal capacity (RC) and Toxicity index (TI). These models are repeatedly used in aquatic phytoremediation studies of metals in aqueous medium [48,156,177,175,176,141,155,44,143,165,158,146,137,166,167,168,171,172,148,139,150,173,210,211] and can also be used in organic pollutant remediation studies.…”

Heavy metals and organic pollutants are ubiquitous environmental pollutants affecting the quality of soil, water and air. Over the past 5 decades, many strategies have been developed for the remediation of polluted water. Strategies involving aquatic plant use are preferable to conventional methods. In this study, an attempt was made to provide a brief review on recent progresses in research and practical applications of phytoremediation for water resources with the following objectives: (1) to discuss the toxicity of toxic chemicals pollution in water to plant, animals and human health (2) to summarise the physicochemical factors affecting removal of toxic chemicals such as heavy metals and organic contaminants in aqueous solutions by aquatic plants; (3) to summarise and compare the removal rates of heavy metals and organic contaminants in aqueous solutions by diverse aquatic plants; and (4) to summarise chemometric models for testing aquatic plant performance. More than 20 aquatic plants specie have been used extensively while duckweed (L. minor), water hyacinth (Eichhornia crassipes), water lettuce (P. stratiotes) are the most common. Overall, chemometrics for performance assessment reported include: Growth rate (GR), Growth rate inhibition (% Inhibition), Metal uptake (MU), translocation/transfer factor (TF), bioconcentration factor (BCF), Percent metal uptake (% MU), Removal capacity (RC) and Tolerance index (TI) while absorption rate have been studied using the sorption kinetics and isotherms models such as pseudo-first-order (PFO), pseudo-second-order (PSO), Freundlich, Langmuir and Temkin. Using modeling and interpretation of adsorption isotherms for performance assessment is particularly good and increases level of accuracy obtained from adsorption processes of contaminant on plant. Conclusion was drawn by highlighting the gap in knowledge and suggesting key future areas of research for scientists and policymakers.
