ClearMultiple endpoints of polyethylene microplastics toxicity in vascular plants of freshwater ecosystems: A study involving Salvinia auriculata (Salviniaceae)
Researchers exposed the freshwater plant Salvinia auriculata to polyethylene microplastics for 28 days and observed reduced growth, thinner leaf tissue, and structural damage to cells. The study found that microplastics adhered to leaf and root surfaces, causing chlorophyll loss, cell membrane damage, and oxidative stress in the plants.
The Response of Duckweed Lemna minor to Microplastics and Its Potential Use as a Bioindicator of Microplastic Pollution
Researchers tested duckweed Lemna minor as a bioindicator for freshwater microplastic pollution by exposing it to polyethylene microbeads, tire wear particles, PET fibers, and natural particles. Polyethylene microbeads adhered to duckweed at 10 times the rate of other particles and reduced root length, suggesting duckweed could serve as a practical monitor for the dominant polyethylene microplastics in freshwater.

Toxic effects of microplastics on aquatic plants
This review examines the toxic effects of microplastics on freshwater and aquatic plants, which are often the first organisms exposed in aquatic ecosystems.

Researchers tested the effects of dimethyl phthalate and polyethylene microplastic fragments on the aquatic plant Lemna minor, finding that while polyethylene showed limited dose-response effects, it did significantly alter chlorophyll content, while the phthalate produced more consistent toxic responses across growth parameters.
Polyethylene microplastics interfere with the nutrient cycle in water-plant-sediment systems
Researchers studied how polyethylene microplastics affect nutrient cycling in freshwater systems containing submerged plants and sediment. They found that the microplastics significantly reduced nitrogen and carbon content in plant leaves and disrupted the microbial communities in sediment responsible for nutrient processing. The study demonstrates that microplastic pollution can interfere with fundamental biogeochemical cycles that maintain the health of aquatic ecosystems.

Both nano- and microplastic particles negatively affected the growth of freshwater macrophytes in sediment-rooted experiments, with nanoplastics causing more pronounced effects at lower concentrations. The findings highlight that aquatic plants, which form the base of many freshwater food webs, are vulnerable to plastic particle pollution.

This study highlights how nylon microplastics from personal care products can harm microscopic plant life in rivers and lakes.
Leaf morphology affects microplastic entrapment efficiency in freshwater macrophytes
Researchers found that leaf morphology significantly affects the ability of freshwater macrophytes (aquatic plants) to trap microplastics, with leaf shape and surface texture influencing particle capture efficiency.
