“…They also play an important role in the structural and functional aspects of aquatic ecosystems by altering water movement regimes (flow and wave impact conditions), providing shelter to fish and aquatic invertebrates and serving as a food source, and altering water quality by regulating oxygen balance, nutrient cycle, and accumulating heavy metals Dhote and Dixit 2009). Their ability to hyperaccumulate heavy metals make them interesting research candidates especially for the treatment of industrial effluents and sewage waste water (Mkandawire et al 2004;Arora et al 2006;Upadhyay et al 2007;Mishra et al 2009;Rai 2010a).The potential of aquatic marcophytes for heavy metal removal has been investigated and reviewed extensively (Brooks and Robinson 1998;Cheng 2003;Prasad and Freitas 2003;Suresh and Ravishankar 2004;Srivastva et al 2008;Dhir et al 2009a;Dhote and Dixit 2009;Marques et al 2009;Rai 2009).

Aquatic macrophytes play an important role in the structural and functional aspects of aquatic ecosystems by altering water movement regimes, providing shelter to fish and aquatic invertebrates, serving as a food source, and altering water quality by regulating oxygen balance, nutrient cycles, and accumulating heavy metals. The ability to hyperaccumulate heavy metals makes them interesting research candidates, especially for the treatment of industrial effluents and sewage waste water. The use of aquatic macrophytes, such as Azolla with hyper accumulating ability is known to be an environmentally friendly option to restore polluted aquatic resources. The present review highlights the phytoaccumulation potential of macrophytes with emphasis on utilization of Azolla as a promising candidate for phytoremediation. The impact of uptake of heavy metals on morphology and metabolic processes of Azolla has also been discussed for a better understanding and utilization of this symbiotic association in the field of phytoremediation.

“…Aquatic macrophytes seem to be especially resistant to the toxicity of a great variety of organic pollutants at concentrations normally encountered in typical wastewater compositions. In addition, numerous studies have shown the capability of many macrophyte species to reduce the aqueous concentrations of various organic xenobiotics such as explosives [40,[105][106][107], petroleum hydrocarbons [36], pesticides [108][109][110] and more recently on some pharmaceuticals [100,[111][112][113][114][115].…”

“…Some authors, such as Ali et al (2013), Dhir et al (2009) andBalabanova et al (2015), report that a BCF greater than 1 indicate that a TF plant species has potential for phytoextraction. However, if the translocation factor is greater than 1, the plant has a higher capacity for metal accumulation in its leaves and stems rather than in its roots.…”

“…Dhir et al (2009) reports that, although the level of uptake potential varies from species to species, and by species of plant and wetland, the free-floating plant, particularly when submerged and emerging, gained major importance in the world by its efficiency in removing various contaminants such as heavy metals, radionuclides, explosives, organic and inorganic pollutants in polluted waters. For this reason, various aquatic plants have been used to remove heavy metals from wastewater (Vardanyan and Ingole, 2006).…”

This study evaluated the bioindication and phytoremediation capacity of the aquatic macrophyte Sagittaria montevidensis by using it to assess the bioconcentration and translocation of heavy metals. A simple sampling was conducted at four sites in the region of Pelotas, southern Brazil, where plants, water and sediments were collected. The plants were subjected to nitric-perchloric acid digestion and the sediments underwent pseudo-total acid digestion. The determination of the elements Cr, Cu, Pb, Ni and Zn in the extracts was performed by flame atomic absorption spectrometry. Physicochemical tests were also carried out on water samples, including pH, electrical conductivity, chlorides, alkalinity, hardness and organic matter, and in sediment samples, moisture and organic matter content. The macrophyte study indicated a Bioconcentration Factor (BCF) and a Translocation Factor (TF), especially for Ni. The results showed that the aquatic macrophyte species S. montevidensis has a phytoextraction capacity, mainly for Ni, and potentially for bioindication of Cu, Ni and Zn.Keywords: aquatic macrophyte, heavy metals, phytoremediation. Avaliação da Sagittaria montevidensis Cham. & Schltdl. como bioindicador e fitoextrator de metais tóxicos RESUMOEste estudo teve como objetivo avaliar a capacidade de fitorremediação e bioindicação da macrófita aquática Sagittaria montevidensis, utilizando como parâmetros a bioconcentração e translocação de metais pesados. Foi realizada uma amostragem simples em quatro locais na região de Pelotas, sul do Brasil, na qual foram coletadas plantas, águas e sedimentos. As plantas foram submetidas a digestão ácida nítrico-perclórica e os sedimentos sofreram a extração pseudo-total de digestão ácida. A determinação dos elementos Cr, Cu, Pb, Ni e Zn nos extratos foi realizada por espectrometria de absorção atômica em chama. Também foram realizados ensaios físico-químicos em amostras de água, incluindo pH, condutividade elétrica, cloretos, alcalinidade, dureza e matéria orgânica e, em amostras de sedimentos, umidade e teor de matéria orgânica. A macrófita aquática estudada apresentou
