Microplastics have emerged as pervasive environmental pollutants, posing significant risks to both terrestrial and aquatic ecosystems worldwide. Current remediation strategies-including physical, chemical, microbial methods-are inadequate for large-scale, in situ removal of microplastics, highlighting the urgent need alternative solutions. Phytoremediation, an eco-friendly cost-effective technology, holds promise addressing these challenges, though its application microplastic pollution remains underexplored. Here we show capacity Eichhornia crassipes (water hyacinth), a fast-growing, floating plant, remove microplastics from contaminated water. Our results that within 48 h, water hyacinth achieved efficiencies 55.3 %, 69.1 68.8 % 0.5, 1, 2 μm polystyrene particles, respectively, with root adsorption identified primary mechanism. Fluorescence microscopy revealed extremely large abundant caps, featuring total surface area exceeding 150,000 mm2 per serve principal sites entrapment microplastics. Furthermore, unique "vascular ring" structure stem prevents translocation aerial tissues, safeguarding leaves potential downstream applications. This study offers first microstructural insight into mechanisms underpinning hyacinth's exceptional resilience, providing promising framework developing phytoremediation strategies mitigate ecosystems.

Coagulation is a widely employed technique for removing suspended particles from water and wastewater, recently, it has gotten attention as popular method the removal of microplastics (MPs). Studies on coagulation-based MPs are still in their infancy, few findings available about this treatment approach, its mechanism, efficiency. Given these gaps, study was designed to comprehensively investigate recent advances via coagulation. The influence various experimental factors such coagulant type, dose coagulant, pH solution, shape critically reviewed. showed that optimizing environmental conditions during coagulation process crucial improving reducing energy costs. efficiency depends optimal reaction conditions, which may vary depending type concentration characteristics or wastewater being treated. Optimizing is, therefore, critical achieving maximum More extensive research required reveal mechanisms controlling floc density pollutants effluent. Consequently, current review aims highlight gaps challenges associated with techniques treatment. Current advancements synthesis chemical modification bio-based coagulants performance could constitute paradigm shift ecosystem protection sustainability. use eco-friendly combining other suggested increase efficacy viability method. This will provide significant insights field researchers, guiding future investigations contributing advancement knowledge.
