Floating filters of nature: exploring the potential of aquatic plants in phytoremediation of microplastic-polluted water.
Chauhan A, Banerjee R
Summary
PubMedWhy it matters This matters because microplastics from your garden runoff, local parks, and stormwater drains end up in rivers and eventually in the fish and tap water you consume — and floating aquatic plants may be nature's own filter to stop that cycle.
Tiny plastic fragments are building up in rivers and lakes worldwide, and they're nearly impossible to remove with traditional filters. Scientists reviewed how floating water plants — the kind you might see covering a pond — can actually grab onto these plastic bits through their roots and leaf surfaces. This natural 'living filter' approach could be deployed in rivers and ponds at low cost, without heavy machinery.
chevron_right Technical Details
Aquatic plants like water hyacinth and duckweed can naturally trap and remove microplastics from polluted waterways using their roots and leaf surfaces, offering a cheap, scalable, and eco-friendly alternative to mechanical water filtration.
Key Findings
Microplastics accumulate at especially high concentrations in stagnant water bodies, making them prime targets for plant-based cleanup strategies.
Two primary mechanisms drive microplastic removal by aquatic plants: surface adsorption onto plant tissues and physical entrapment within dense root structures.
Phytoremediation using aquatic plants is identified as more scalable and economical than conventional mechanical filtration for in-situ microplastic removal.
Abstract Preview
In recent years, a substantial upsurge in the environmental contamination caused by microplastics (MPs) has raised global concern. They are non-biodegradable compounds that can stay in water bodies...
