ClearThe bioaccumulation and ecotoxicity of co-exposure of per(poly)fluoroalkyl substances and polystyrene microplastics to Eichhornia crassipes
This study found that when microplastics and forever chemicals (PFAS) coexist in water, the microplastics increase how much PFAS accumulates in water hyacinth plants and worsen the toxic effects compared to PFAS exposure alone. The finding is relevant to human health because it shows microplastics can amplify the harmful effects of other pollutants already present in the environment.
Characteristics of organic matter driven by Eichhornia crassipes during co-contamination with per(poly)fluoroalkyl substances (PFASs) and microplastics (MPs)
Researchers examined how co-contamination with per- and polyfluoroalkyl substances and polystyrene microplastics affects dissolved organic matter released by the floating plant Eichhornia crassipes. They found that these contaminants increased organic matter release by 32 to 77% and altered the composition of fluorescent compounds in the water. The study reveals that emerging contaminant mixtures can disrupt the organic matter cycling driven by aquatic plants, with potential cascading effects on water ecosystems.

Rhizospheric bacterial communities against microplastics (MPs): Novel ecological strategies based on the niche differentiation
Researchers studied how bacterial communities living around plant roots adapt when exposed to microplastics in soil. They found that rhizosphere bacteria developed distinct survival strategies depending on their ecological niche, with some species thriving while others declined in the presence of plastics. The study reveals that microplastics can reshape the microbial communities that plants depend on for nutrient uptake and disease resistance.
The emerging threat of hybrid microplastics: Impacts on per(poly)fluoroalkyl substance bioaccumulation and phytotoxicity in floating macrophytes
This study examined how mixtures of different microplastic types interact with PFAS (forever chemicals) and found that more diverse microplastic mixtures increased the absorption and toxicity of PFAS in aquatic plants. The complexity of real-world microplastic pollution, where multiple plastic types coexist, appears to make forever chemical contamination worse. This finding is important because most lab studies test single plastic types, potentially underestimating the actual environmental risk.
Potential impacts of polyethylene microplastics and heavy metals on Bidens pilosa L. growth: Shifts in root-associated endophyte microbial communities
Researchers found that polyethylene microplastics in soil contaminated with heavy metals significantly stunted plant growth, reducing root length by nearly 49% and increasing harmful reactive oxygen species in plant tissues. The microplastics also shifted the soil's microbial communities toward stress-resistant species, demonstrating how plastic pollution can disrupt the soil ecosystem that supports our food supply.

Microplastics and co-pollutant with ciprofloxacin affect interactions between free-floating macrophytes
Researchers found that polyethylene microplastics and ciprofloxacin co-pollutants altered competitive interactions between free-floating macrophytes, with combined exposure affecting plant growth and physiological responses differently than individual pollutant exposure.
Single and combined toxicity effects of microplastics and perfluorooctanoic acid on submerged macrophytes and biofilms
Researchers tested the combined effects of four common microplastic types and PFOA (a forever chemical) on aquatic plants and their associated biofilms. The pollutants together caused more damage to plant growth, photosynthesis, and microbial communities than either pollutant alone. Since microplastics and PFOA frequently co-occur in the environment, their combined toxic effects on aquatic ecosystems could have downstream consequences for water quality and human exposure.
Effects of polyethylene microplastics on the microbial community structure of maize rhizosphere soil
Researchers investigated how polyethylene microplastics from agricultural films affect the microbial communities in crop root zones (rhizosphere), finding shifts in bacterial diversity and function. Disrupting soil microbiomes through microplastic contamination could have downstream effects on soil fertility and crop health.
Rhizosphere Keystone Microbiomes Promote Invasive Plant Growth under PLA and PVC Microplastic Stress: A Comparative Study with Native Species
Researchers compared how invasive and native plant species respond to soil contaminated with biodegradable and non-biodegradable microplastics. Invasive plants experienced less growth inhibition and selectively enriched beneficial bacteria in their root zones, forming more stable microbial networks. The study suggests that microplastic contamination in soils may inadvertently give invasive species a competitive advantage over native plants.
Response strategies of stem/leaves endophyte communities to nano-plastics regulate growth performance of submerged macrophytes.
Nano-polystyrene exposure changed the composition and activity of endophytic bacterial communities in the stems and leaves of aquatic macrophytes, with some endophyte shifts helping plants maintain growth by modulating stress responses, revealing a microbiome-mediated tolerance mechanism.
Effect of flumetsulam alone and coexistence with polyethylene microplastics on soil microbial carbon and nitrogen cycles: Elucidation of bacterial community structure, functional gene expression, and enzyme activity
Researchers tested how the herbicide flumetsulam interacts with polyethylene microplastics in soil and found that both individually and together they reduced bacteria and fungi populations. When microplastics were present alongside the herbicide, the soil bacterial community shifted more dramatically, though carbon and nitrogen cycling remained largely unchanged. The study suggests that the combined presence of herbicides and microplastics in agricultural soil creates distinct effects on microbial life compared to either contaminant alone.
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.

Researchers used a controlled pot experiment to assess microplastic effects on wetland plant growth, soil microbial communities, and nutrient cycling, finding that MPs altered soil enzyme activity and shifted bacterial community composition but had variable effects on plant growth depending on plastic type.
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.

The study identified specific PFAS compounds with the highest masking risk, providing new insights for regulating combined pollutant risks to aquatic ecosystems.

Researchers studied how microplastics of different sizes and concentrations affect the microbial communities living inside Chinese flowering cabbage tissues. They found that microplastic exposure significantly altered the endophytic bacteria in roots and stems, increasing the abundance of potentially harmful bacterial species. The study suggests that microplastic contamination in agricultural soils may compromise plant health by disrupting the beneficial microorganisms that naturally reside within crop tissues.
