“…In case of reed plants, these plants are characterized by their effective antioxidative metabolism in presence of high concentrations of metal contaminants 92 . Accordingly, these plants function as phytostabilization for Zn 2+ and Cu 2+ 93 while exhibit high absorption capacity for Cd 2+ 94 . Similar results indicate that the removal efficiencies of Cu and Cd from aqueous solutions by Phragmits australis were 50.8 and 42.2%, respectively 92 .…”

To cope with water crisis, wastewater reuse has been introduced as a potential source for irrigation. On the other hand, irrigation with wastewater may negatively affect the surroundings. In this study, reed plant (Phragmits australis) and its biochar were tested as low-cost treatments to enhance the efficiency of wastewater reclamation in wetlands within only 72 h. The investigated water was of low irrigation quality and exhibited high contents of BOD5 and fecal coliform. Moreover, this water contained high levels of soluble cations and anions; besides, being marginally contaminated with Cu, Mn and Cd. After 2 days in the sedimentation unit, wastewater was subjected to three reclamation treatments in parallel (each lasted for 24 h): (1) a “sand & gravel bed”, (2) “reed plants grown on a sand & gravel bed” and (3) “biochar + a sand & gravel bed”. The results showed that all treatments decreased BOD5, fecal coliform, total cations and anions, with superiority for the second and third treatments. The levels of the potentially toxic elements also decreased to values within the permissible levels. Although the aforementioned wastewater treatment processes upgraded the quality of this water, it remained in the poor grade. Biochar or reed plants grown on sand and gravel beds significantly improved wastewater quality to the medium quality grade, with superiority for biochar treatment. In conclusion, investigated treatments are guaranteed in wetlands for wastewater reclamation; yet, further protocols should be followed to achieve safe handling of this water and attain the sustainable goals.

“…In the last decades, rapid industrialization, urbanization, and population growth have led to signi cant increases in pollutant levels in water and soil resources (CPBC, 2008;SOOD et al, 2012). This poses a serious problem, affecting aquatic ecosystems, agriculture, and human health (GUPTA et al, 2010), with heavy metals being a major source of water and soil contamination (SELLAL et al, 2019). These heavy metals cannot be degraded through microbial or chemical processes, and their accumulation in the bodies of animals and humans along the food chain can cause DNA damage, carcinogenic effects, and the induction of mutations (EBRAHEM et al, 2019).…”

“…Several technologies have been employed for the removal of toxic metals from contaminated environments, but they tend to be expensive, ineffective at low concentration levels, and may generate a large amount of waste (SELLAL et al, 2019). Phytoremediation, on the other hand, represents a biological, cost-effective, and eco-friendly clean-up approach that utilizes plants, their rhizospheres, and associated micro-organisms to degrade, remove, or remediate contaminants from soil and water while promoting vegetation on the land.…”

Heavy metals represent a serious source of water and soil contamination, mainly due to their non-biodegradable nature. Their bioaccumulation occurs in plants and other trophic levels, including animals, consequently affecting humans and causing various side effects. Phytoremediation offers a biological, cost-effective, and environmentally friendly cleaning solution, utilizing plants to remove contaminants from soil and water. This study aims to establish the chemical composition of Pontederia parviflora and Salvinia auriculata using liquid chromatography and evaluate the role of their secondary metabolites in passive phytoremediation by these plants. Although the results are not aligned with the initial hypothesis of metal removal from the liquid medium (sequestration and chelation of metals), the amount of metal removed still represents a positive outlook for technique enhancement. Furthermore, this research challenges the notion presented in the literature, as secondary metabolites were considered contaminant sequesters. The removal of these metabolites from the biomass of these macrophytes did not significantly impact their phytoremediation performance.

“…They are toxic, persistent and can negatively affect all life forms. In humans they are absorbed directly by ingestion or inhalation and concentrated in different parts of the human body resulting in chronic or acute effects on human health, including physiological disorders of the respiratory system, renal and gastrointestinal (Sellal et al 2019a) 2 .…”

Introduction: Heavy metals that enter organisms can cause illness and disease. Chelation therapy is a solution that uses chelating agents to protect these organisms by high accumulation. Materials and methods: The objective of this study is to evaluate the capability of different roots extracts from reed or EDTA (as standard) to complexate iron using, ferrozine-ferrous reducing assay or Zn and Cu using the murexide-Zn or Cu reducing assay in vitro. Results: the results proved that the organic phase of the first extract and EDTA (standard chelator), have the strongest chelation activities with respective rates of 70% and 97% for iron, 55% and 56% for zinc and 47% and 88% for copper compared to the control groups considered to be 100% of the complexation. Finally, the HPLC analysis showed the presence of six organic acids, which are probably responsible for this effect. Conclusion: The hexane extract and EDTA (standard), have the strongest chelation activities. Keywords: Phragmites australis, Chelation, Heavy metals, Organic acids, Ferrozine, Murexide.
