Proposal of Invader Pontederia crassipes as a Savior of Micro and Macro Size Plastic Pollution
Summary
This study was the first to evaluate microplastic and macroplastic capture potential of the invasive water hyacinth, finding 3,691 particles in the roots of 12 specimens, with fragments dominating. The results suggest this widely distributed invasive plant may passively accumulate plastic particles from aquatic environments.
This study is the first report evaluating the microplastic (MP) and macroplastics capture potential of Pontederia crassipes. Total of 3691 (508 microplastic and 3183 macroplastic) particles were extracted from the roots of 12 examined specimens. Mean macroplastic abundance in the roots was found as 265±44 macroplastic/specimen. Majority of the extracted macroplastics were fragment in shape, blue in color. Mean microplastic abundance was found as 42±23 MPs/specimen. Majority of the extracted microplastics were fragment in shape, blue in color and less than 500 μm in size. Results of this preliminary study showed that this species have significant ability to adsorb micro and macroplastics by the roots which makes them perfect employees for integrated floating systems.

First Evidence of Microplastic in the Roots of Eichhornia Crassipes (mart.) Solms (1883) at the Delmiro Gouveia Paulo Afonso Reservoir – Ba - Submedio São Francisco
This Brazilian study is the first to document microplastics in the roots of water hyacinth (Eichhornia crassipes) in the Sao Francisco River basin, finding 211 microplastic particles in root samples across multiple collection months. Fibers were the dominant type in both plant roots and water samples, highlighting the plant's role in accumulating suspended microplastics.
Phytoremediation of microplastics by water hyacinth
Researchers found that water hyacinth, a fast-growing floating plant, can remove 55-69% of microplastics from contaminated water within 48 hours through root adsorption. The plant's massive root surface area traps plastic particles, while a special structure in the stem prevents the plastics from reaching the leaves. This study offers a promising natural, low-cost approach to cleaning microplastics from waterways.
Tracing and trapping micro- and nanoplastics: Untapped mitigation potential of aquatic plants?
Researchers used fluorescently labeled polystyrene particles to trace microplastic and nanoplastic uptake in three aquatic plant species, finding that nanoplastics concentrated primarily in roots via apoplastic transport with bioconcentration factors up to 306, suggesting floating plants like water hyacinth may be useful for removing plastic from contaminated water.
Water hyacinths retain river plastics
Researchers investigated how water hyacinths, an invasive aquatic plant common in tropical rivers, interact with floating plastic debris. They found that dense water hyacinth patches efficiently trap surface plastics, potentially influencing whether plastic waste reaches the ocean. The study suggests that while water hyacinths are typically considered a nuisance species, they may play an unintended role in retaining river plastics.
Plastic plants: Water hyacinths as driver of plastic transport in tropical rivers
Researchers studied how water hyacinth plants act as drivers of plastic transport in tropical freshwater rivers, finding that the floating plants aggregate and carry large quantities of plastic debris. Understanding this mechanism is important for predicting and intercepting plastic before it reaches the ocean as microplastics.
