Removing Microplastics from Aquatic Environments with Iris 2 Pseudacorus and Lythrum anceps
Summary
Researchers analysed the effectiveness of Iris pseudacorus and Lythrum anceps wetland plants in removing microplastics from aquatic environments, examining whether these macrophytes can accumulate and retain plastic particles and reduce adverse physiological effects on aquatic organisms.
(1) Background: Since microplastics in the aquatic environment are difficult to prevent and can cause adverse physiological and biochemical reactions to various organisms, we aimed to analyze the effectiveness of an eco-friendly removal method using aquatic plants with high ornamental value and excellent water purification ability. (2) Methods: Iris pseudacorus and Lythrum anceps were planted in tap water contaminated with microplastics to analyze the removal rate and root adsorption of microplastics. (3) Results: The amount of microplastics in the planting boxes of Iris pseudacorus and Lythrum anceps was significantly reduced, and the adsorption of microplastics on the roots was confirmed. (4) Conclusions: It was found that the removal of microplastics in water by aquatic plants is effective and that microplastic pollution does not significantly affect plant growth. However, the removal of microplastics by adsorption on plant roots may be affected by various environmental factors, so it is necessary to consider various limitations.

Iris pseudacorus and Lythrum anceps as Plants Supporting the Process of Removing Microplastics from Aquatic Environments—Preliminary Research
In a four-month experiment, two aquatic plant species (yellow flag iris and loosestrife) significantly reduced microplastic concentrations in water by trapping the particles on their root systems. The plants effectively removed both small (46 micron) and larger (140 micron) polyethylene particles without negative effects on plant growth. This suggests that aquatic plants could be used as a natural, low-cost method for filtering microplastics from contaminated water.
The effects of polypropylene microplastics on the removal of nitrogen and phosphorus from water by Acorus calamus, Iris tectorum and functional microorganisms
Researchers investigated how polypropylene microplastics affect the ability of aquatic plants and their associated microorganisms to remove nitrogen and phosphorus from water. They found that microplastic stress reduced the nutrient absorption capacity of the plants and altered the microbial communities responsible for nitrogen and phosphorus cycling. The study suggests that microplastic pollution may undermine the effectiveness of wetland-based water purification systems.
Effects of macrophytes on micro – And nanoplastic retention and cycling in constructed wetlands
This study tested how the presence of aquatic plants (macrophytes) in constructed wetlands affects the capture and cycling of micro- and nanoplastics. Researchers found that planted wetlands were significantly better at intercepting nanoplastics and also improved nitrogen and phosphorus removal even when exposed to plastic particles. The findings suggest that including macrophytes in constructed wetland designs can enhance their ability to manage plastic pollution in water.
Phytoremediation: A promising approach to remove microplastics from the aquatic environment
This study investigated the interactions between aquatic macrophytes and microplastics as the basis for developing phytoremediation strategies, finding that certain macrophyte species can accumulate MPs from water and sediment and may be candidates for MP removal from contaminated aquatic environments.
Understanding microplastic retention in surface flow constructed wetlands: The impact of aquatic macrophytes
This study tested how well constructed wetlands with different aquatic plants retain three common types of microplastics: polyethylene beads, tire wear particles, and synthetic fibers. Plants with complex leaf structures trapped more microplastics than simpler plants or unvegetated areas. The findings suggest that planted wetlands could serve as a nature-based solution for filtering microplastics from water before they reach rivers and drinking water sources.
