ABSTRACT:
This article provides a comprehensive overview of recent advancements in life sciences, examining the biological mechanisms, key species, practical applications, challenges, and future directions of hydrophyte-based bioremediation for metals such as cadmium, lead, mercury, and zinc from industrial, mining, and agricultural sources. The studies show that hydrophytes such as Eichhornia crassipes and Phragmites australis facilitate effective metal removal through phytoaccumulation, phytostabilization via root immobilization, biochemical detoxification employing chelators like phytochelatins and antioxidants, and microbial synergies with bacteria such as Pseudomonas spp., with efficacy modulated by factors including pH and root biomass; comparative tables underscore species-specific strengths, illustrating applications in ecosystem restoration (e.g., diminishing lead mobility in wetlands), alignment with Sustainable Development Goals 3 and 6 for promoting health and clean water, and circular economy principles through biomass repurposing for bioenergy. Challenges such as toxicity at elevated concentrations, environmental variability, scalability constraints, and policy deficiencies can be mitigated through genetic engineering (e.g., overexpressing metallothionein genes to bolster tolerance), nanotechnology, and bioaugmentation. Ultimately, integrating omics technologies, microbial engineering, and supportive policies positions hydrophytes as a promising, ecologically sound strategy for mitigating global heavy metal pollution.
