“…Metal removal using living organisms has recently received a lot of public interest and research and development funding [17][18][19]. Thus, several studies have recommended phytoremediation as an environmentally friendly and cost-effective method for removing pollutants from aquatic ecosystems [20,21]. Research on phytoremediation in aquatic ecosystems is ongoing, but a number of studies have been promising, identifying a variety of aquatic macrophytes, such as duckweed, i.e., [22,23], and water hyacinth, i.e., [24,25], being effective in removing metals from water and sediments.…”

Human activities have resulted in an increase in metal pollution within aquatic ecosystems, with most of these metals ending up being taken by macrophytes. Thus, these macrophytes provide an opportunity to study metal pollution dynamics and the role that macrophytes play in potentially translocating and accumulating these metals. Here, we studied three macrophyte species, namely Phragmites australis, Schoenoplectus corymbosus, and Typha capensis, and assessed their potential to be utilized in the phytoremediation of metals in an Austral subtropical river across three seasons. We measured P, K, Ca, Mg, B, Fe, Zn, Cu, and Mn concentrations in macrophyte roots, stems, and leaves, and we further quantified the metal bioconcentration factor (BCF). The N, Ca, and Mg concentrations were generally high in P. australis leaves across all seasons. In general, high Na, Mg, and Ca concentrations were observed in T. capensis across seasons. The bioconcentration factor (BCF) values were generally low (<1) in most macrophyte parts for most metals during the cool-dry season, with the exception of Na, which had high BCF values > 1 (i.e., accumulators) across the different macrophyte parts. We found that P. australis and S. corymbosus have the potential to accumulate metals such as B, Na, Mg, Ca, and N and also have high phytoremediation potential for the studied metals. We found that the studied macrophytes were good at phytoremediation within the river system; however, for any treatment of polluted systems, it is better to use a combination of different macrophytes, as some were better at translocating certain metals than others.
