“…Necrosis and chlorosis were observed on leaves of Salvinia minima Baker (Salviniaceae) on the second day of exposure to arsenic (Guimarães et al, 2012). Casagrande et al (2018) observed effects similar to those of this study on the external morphology in plants of S. biloba, mainly in the leaves, to which the authors correlated the rupture of the limbus and increase of the aerenchyma in the concentrations of 0.05 and 0.2 of mercury (Hg), respectively, confirmed in internal morphological analysis. The most common action of copper toxicity on plants is the inhibition of the formation of photosynthetic pigments, resulting in direct effects on plant productivity (Jung et al, 2015).…”

“…Copper is one of the most common metals in nature, present in living beings as an essential constituent, originating from geological processes or from residues arising from anthropic activities (Casagrande et al, 2018;Holtra & Zamorska-Wojdyła, 2020). It is widely used in agricultural industries, cosmetics, coatings, fungicides, food industry, chemical industry, fuel additives, textile industries, medical industry, paints, plastics, wastewater treatment, and electronics (Rajput et al, 2017).…”

Aquatic plants are often exposed to metal contamination. The study evaluated the bioaccumulation of copper (Cu) ions in aqueous solution by the biomass of leaves and roots of the macrophyte Salvinia natans. Plants of S. natans were submitted to culture solutions with different concentrations of Cu ions, evaluated at intervals of seven days. The leaf and root samples were separately subjected to atomic absorption spectroscopy with flame atomization to assess the concentration of copper accumulated in its biomass. The results demonstrated a pattern of accumulation dependent on the concentration of the metal in the culture medium and the time of exposure of the plants to the contamination. The accumulation was greater in the biomass of the roots when compared to the leaves. Throughout the experiment, toxicity symptoms were observed in the morphology of plants subjected to all copper concentrations, demonstrating the macrophyte's viability for bioindicating the toxicity of this metal in aquatic environments. A high accumulation of copper ions was obtained both in the biomass of the roots and leaves of the plants, confirming their potential bioaccumulator of Cu. The analysis of biomass suggests an important characteristic of metal compartmentalization by the plant, associating the absorption by the roots and the possible transfer to the leaves. In general, our results show that S. natans is an organism with a potential bioindicator and bioaccumulator of Cu and consists of a viable cost-effective option for phytoremediation of aquatic environments contaminated by metals

“…They have the ability to remove heavy metals from water and sediments [240][241][242]. Some of the famous submerged plants such as parrot feather (Myriophyllum spicatum), coontail or hornwort (Ceratophyllumdemersum), pondweed (Potamogeton Crispus), American pondweed (Potamogetonpectinatus), Mentha Aquatica, Vallisneria spiralis and water mint are well known for their ability to accumulate Zn, Cr, Fe, Cu, Cd, Ni, Hg and Pb [152,154,155,157,243].…”

Application of Floating Aquatic Plants in Phytoremediation of Heavy Metals Polluted Water: A Review

et al. 2020

Heavy-metal (HM) pollution is considered a leading source of environmental contamination. Heavy-metal pollution in ground water poses a serious threat to human health and the aquatic ecosystem. Conventional treatment technologies to remove the pollutants from wastewater are usually costly, time-consuming, environmentally destructive, and mostly inefficient. Phytoremediation is a cost-effective green emerging technology with long-lasting applicability. The selection of plant species is the most significant aspect for successful phytoremediation. Aquatic plants hold steep efficiency for the removal of organic and inorganic pollutants. Water hyacinth (Eichhornia crassipes), water lettuce (Pistia stratiotes) and Duck weed (Lemna minor) along with some other aquatic plants are prominent metal accumulator plants for the remediation of heavy-metal polluted water. The phytoremediation potential of the aquatic plant can be further enhanced by the application of innovative approaches in phytoremediation. A summarizing review regarding the use of aquatic plants in phytoremediation is gathered in order to present the broad applicability of phytoremediation.

“…This technique dates to 1970s, when radioactive elements were found in algae [1]. It is based, then, on the binding capacity between the metal and the adsorbent, the latter being alive or dead microorganisms [8], biomass [9,1], bacteria [10], fungi [11], algae [7,[12][13][14] or algae as a potential carbon source [15]. Among these biomaterials, the algae have attracted special interest due to their abundance, low cost, considerable efficiency and the possibility of recovery of the metal.…”
