“…Therefore, it was imperative to develop alternative technologies that are economical as well as eco-friendly. In recent years, aquatic macrophytes have been used worldwide for the removal of toxic pollutants, including heavy metals and pharmaceutical products from industrial effluent and municipal wastewater (Allende et al 2011;Augustynowicz et al 2010;Bonano 2012;Caselles-Osorio and Garcia 2007;Cui et al 2011;Ghemandi et al 2007;Hua et al 2013;Langergraba 2005;Maine et al 2009;Marchand et al 2010;Ong et al 2010;Ranieri et al 2011;Saeed and Sun 2012;Tang et al 2010;Vymazal 2005;Wen et al 2010;Wojciechowska and Waara 2011;Xue et al 2010;Zhang et al 2012). Main mechanisms of removal of heavy metals by aquatic plants are plant uptake, precipitation and co-precipitation as insoluble salts, and binding to the substrate (Brix 1994;Ranieri et al 2011).…”

The present work deals with a promising approach for the removal of heavy metals from secondary treated wastewater using aquatic plants, which are economic and effective in separating metals from polluted water. Since the conventional sewage treatment processes were inefficient to remove heavy metals from wastewater, batch experiments of Phragmites australis, Typha latifolia and P. australis and T. latifolia grown in association and reference (unplanted) were carried out for 15 days of retention time for the removal of copper (Cu), cadmium (Cd), chromium (Cr), nickel (Ni), iron (Fe), lead (Pb), and zinc (Zn) from the secondary treated effluent. Significantly, higher removal of the heavy metals in planted set than the reference revealed role of plants in their removal (analysis of variance, p \ 0.05). Higher removal of Cr, Fe, and Zn (66.2 ± 3.5, 70.6 ± 1.2, and 71.6 ± 3.9 %) in the combination of the P. australis and T. latifolia than their individual culture suggested synergistic effect of both the plants in the removal of these metals. Positive relationship was observed between retention time and the removal of heavy metals. Mass balance equation has revealed that the loss of heavy metals in wastewater was equivalent to the net accumulation of heavy metals in plant and loss of heavy metals in natural degradation. P. australis showed higher accumulative capacities for Cu, Cd, Cr, Ni, Fe, and Pb than those of T. latifolia. The P. australis and T. latifolia grown in association might be utilized for the heavy metal removal in the tropical environment.

“…Wetlands, both natural and constructed, receiving wastewater, have been shown to reduce EC and stabilize pH values towards neutral (Sasaki et al 2003;Maine et al 2009). In this study, EC reductions appear to be facilitated by the presence of emergent macrophytes, while the pH stabilization was not significantly related to their presence.…”

The storage of coal combustion residue (CCR) in surface water impoundments may have an impact on nearby water quality and aquatic ecosystems. CCR contains leachable trace elements that can enter nearby waters through spills and monitored discharge. It is important, therefore, to understand their environmental fate in affected systems. This experiment examined trace element leachability into freshwater from fly ash (FA), the most common form of CCR. The effects on water quality of FA derived from both high and low sulfur coal sources as well as the influences of two different emergent macrophytes, Juncus effusus and Eleocharis quadrangulata, were evaluated in wetland microcosms. FA leachate dosings increased water electric conductivity (EC), altered pH, and, most notably, elevated the concentrations of boron (B), molybdenum (Mo), and manganese (Mn). The presence of either macrophyte species helped reduce elevated EC, and B, Mo, and Mn concentrations over time, relative to microcosms containing no plants. B and Mo appeared to bioaccumulate in the plant tissue from the water when elevated by FA dosing, while Mn was not higher in plants dosed with FA leachates. The results of this study indicate that emergent macrophytes could help ameliorate downstream water contamination from CCR storage facilities and could potentially be utilized in wetland filtration systems to treat CCR wastewater before discharge. Additionally, measuring elevated B and Mo in aquatic plants may have potential as a monitoring tool for downstream CCR contamination.

“…It has been investigated that some of macrophytes such as Typha, Phragmites, Eichhornia, Azolla, Lemna, Glyceria grandis, Scirpus validus, Spartina pectinata, etc., are capable of uptake and accumulate a variety of heavy metals (e.g., Cd, Pb, Cr, Zn, Hg, Ni, etc.) and metalloids (e.g., Se) that are present within high concentrations in wastewater (de Souza et al 1999;Lin and Terry 2003;Cheng et al 2002;Deng et al 2004;Karathanasis and Johnson 2003;Liao and Chang 2004;Maine et al 2009;Stottmeister et al 2003;Türker et al 2014;Vymazal and Šveha 2012;Weis and Weis 2004;Ye et al 2001). Some macrophytes can be used to treat more than one metal, and these plants can accumulate heavy metals in concentrations 100,000 times greater than in the associated water (Marchand et al 2010).…”

“…Phragmites australis has been identified as the most suitable emergent plant species for toxic metal ion removal (Marchand et al 2010), but the performance of Phalaris arundinacea is very much similar to Phragmites australis as do Typha domingensis, Typha latifolia, and Phragmites karka (Maine et al 2009;Marchand et al 2010;Vymazal 2007). Phragmites australis and Phalaris arundinacea species have also been used for treating alkali metals such as Na, Mg, K, and Ca, and the results of this study provide comprehensive information on the retention and sequestration of such alkali metals in vegetation during municipal wastewater treatment in constructed wetlands with subsurface horizontal flow (Vymazal and Šveha 2012).…”
