“…Metal(loid)s combinations in environmental matrix can have synergistic (stronger) or antagonistic (weaker) toxicity, mobility, and bioavailability, due to shared mechanisms, altered uptake, or competition (Zhai et al 2023). Understanding these interactions is crucial for quantifying the capacity for environmental remediation and toxic effects (Moukadiri et al 2024). Due to their persistent and toxic character, the remediation of metal(loid) contaminated environments is of paramount importance and generally strictly regulated (Lee and Kim 2019; Mushtaq et al 2022).…”

Natural based solutions, notably constructed/artificial wetland treatment systems, rely heavily on identification and use of macrophytes with the ability to tolerate multiple contaminants and grow for an extended period to reduce contamination. The potential to tolerate and remediate metal(loid) contaminated groundwater from an industrial site located in Flanders (Belgium) was assessed for 10 wetland macrophytes (including Carex riparia, Cyperus longus, Cyperus rotundus, Iris pseudacorus, Juncus effusus, Lythrum salicaria, Menta aquatica, Phragmites australis, Scirpus holoschoenus, and Typha angustifolia). The experiment was conducted under static conditions, where plants were exposed to polluted acidic (pH~4)water, having high level of metal(loid)s for 15 days. Plant biomass, morphology, and metal uptake by roots and shoots were analysed every 5 days for all species. T. angustifolia and S. holoschoenus produced ~3 and ~1.1 times more dried biomass than the controls, respectively. For S. holoschoenus, P. australis, and T. angustifolia, no apparent morphological stress symptoms were observed, and plant heights were similar between control and plants exposed to polluted groundwater. Higher concentrations of all metal(loid)s were detected in the roots indicating a potential for phytostabilization of metal(loid)s below the water column. For J. effusus and T. angustifolia, Cd, Ni, and Zn accumulation was observed higher in the shoots. S. holoschoenus, P. australis, and T. angustifolia are proposed for restoration and phytostabilization strategies in natural and/or constructed wetland and aquatic ecosystems affected by metal(loid) inputs.

“…Pollution and increased demand due to population development have resulted in a widespread scarcity of safe drinking water in many locations around the world (Sukmana et al, 2021). Heavy metal ions in wastewater are a form of pollution that has caused serious health problems (Sharma et al, 2023;Moukadiri et al, 2024). These ions are of special significance because of their persistence in the environment, long-term accumulation, and potential threat to human health via the food chain.…”

Engineered nanomaterials have emerged as a promising technology for water treatment, particularly for removing heavy metals. Their unique physicochemical properties enable them to adsorb large quantities of metals even at low concentrations. This review explores the efficacy of various nanomaterials, including zeolites, polymers, chitosan, metal oxides, and metals, in removing heavy metals from water under different conditions. Functionalization of nanomaterials is a strategy to enhance their separation, stability, and adsorption capacity. Experimental parameters such as pH, adsorbent dosage, temperature, contact time, and ionic strength significantly influence the adsorption process. In comparison, engineered nanomaterials show promise for heavy metal remediation, but several challenges exist, including aggregation, stability, mechanical strength, long-term performance, and scalability. Furthermore, the potential environmental and health impacts of nanomaterials require careful consideration. Future research should focus on addressing these challenges and developing sustainable nanomaterial-based remediation strategies. This will involve interdisciplinary collaboration, adherence to green chemistry principles, and comprehensive risk assessments to ensure the safe and effective deployment of nanomaterials in heavy metal remediation at both lab and large-scale levels.

The potential to tolerate and remediate metal(loid) contaminated groundwater from an industrial site located in Flanders (Belgium) was assessed for 10 wetland macrophytes (including Carex riparia Curtis, Cyperus longus Baker, Cyperus rotundus L., Iris pseudacorus L., Juncus effusus L., Lythrum salicaria L., Mentha aquatica L., Phragmites australis Trin. ex Steud., Scirpus holoschoenus L., and Typha angustifolia L.).
