ClearImpact of microplastics on terrestrial ecosystems: A plant-centric perspective
This review focuses on how microplastics affect plants and soil health in agricultural settings, an area that has received less attention than marine microplastic pollution. The researchers describe how microplastics can alter soil structure, disrupt microbial communities, and enter plant tissues through unique transport mechanisms. The study highlights that agricultural soils are a major sink for microplastics, with potential consequences for food safety and crop productivity.
Impacts of microplastics on terrestrial plants: A critical review
This review examines how microplastics affect land-based plants, finding that they can alter soil structure, disrupt beneficial soil microbes, and reduce plant growth. Microplastics also carry toxic chemicals like plasticizers and heavy metals that can be taken up by plant roots and enter the food chain. The findings raise concerns about human health since contaminated crops could be a hidden source of microplastic and chemical exposure in our diets.
Source, fate, toxicity, and remediation of micro-plastic in wetlands: A critical review
Researchers reviewed how microplastics enter, accumulate in, and damage natural wetlands — ecosystems that filter water and support biodiversity — finding that while wetlands may actually trap plastic particles like a sink, the resulting contamination poses serious ecological risks that are still poorly understood.
What influences microplastic trapping in coastal marshes? Exploring vegetation diversity as a driver of accumulation
This study explored how the diversity of plant species in coastal marshes influences how many microplastics get trapped there, finding that vegetation composition is a meaningful driver of plastic accumulation. Coastal marshes act as natural filters catching plastic before it reaches the open ocean, so understanding what makes them more or less effective has implications for both conservation and plastic pollution management.

A vegetation strategy to balance the hazardous level of microplastics in the land–sea interface through rhizosphere remediation
Researchers reviewed how plants — especially aquatic plants in coastal wetlands and estuaries — can trap and break down microplastics through their root systems and surrounding soil microbes, a process called phytoremediation. Aquatic plants show particular promise because their roots are constantly submerged in contaminated water, giving them more exposure and capture potential than land-based crops.
Unraveling the toxic mechanisms of microplastics in aquatic ecosystem: A case study on Vallisneria natans and Myriophyllum verticillatum
Researchers exposed two submerged aquatic plant species (Vallisneria natans and Myriophyllum verticillatum) to PVC, polystyrene, and polyethylene microplastics at three concentrations, finding that all three types significantly inhibited photosynthesis and growth and triggered oxidative stress, with effects varying by plastic type and plant species.
Microplastics: toxicity and tolerance in plants
Researchers reviewed how microplastics harm both land plants and water plants by disrupting their growth, nutrient uptake, and genetic function, while also triggering the plants' own defense systems in response. Understanding how plants tolerate microplastic exposure is important because contaminated crops could eventually affect human health through the food chain.
Microplastics: a review of their impacts on different life forms and their removal methods
This review provides a broad overview of how microplastics affect different forms of life, from soil organisms and plants to aquatic species and humans. Researchers found that the primary harmful mechanisms involve oxidative stress, immune disruption, and interference with nutrient uptake and photosynthesis. The study also covers various removal methods including coagulation, membrane filtration, and biological degradation approaches.
Planting Enhances Soil Resistance to Microplastics: Evidence from Carbon Emissions and Dissolved Organic Matter Stability
Researchers found that growing plants in soil contaminated with microplastics helped protect the soil ecosystem compared to unplanted soil. The root systems of plants stabilized the soil's microbial communities and reduced the carbon emissions caused by microplastic pollution, suggesting that maintaining plant cover could be one strategy to limit the environmental damage from microplastics in farmland.
Potential synergy of microplastics and nitrogen enrichment on plant holobionts in wetland ecosystems
This review explores how microplastics and excess nitrogen fertilizer may work together to harm wetland plant health by disrupting the beneficial microbes that live on and around plant roots. The combination could accelerate microplastic breakdown while simultaneously weakening plant defenses and nutrient cycling. Since wetlands help filter water that people use, damage to these ecosystems could indirectly affect water quality and human health.
Plant-driven strategies for mitigating microplastic pollution in agricultural ecosystems
Researchers review how microplastics damage agricultural soils and crops — disrupting soil structure, starving plants of nutrients, and triggering oxidative stress — and explore plant- and microbe-based strategies like root-associated bacteria and biochar amendments as promising but underexplored tools for cleaning up plastic-contaminated farmland.
Microplastic residues in wetland ecosystems: Do they truly threaten the plant-microbe-soil system?
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.
Microplastics as emerging stressors in plants: biochemical and metabolic responses
This review examines how microplastics act as environmental stressors in plants, disrupting biochemical and metabolic processes including photosynthesis, antioxidant defenses, and nutrient uptake, with effects varying by polymer type, particle size, and concentration.
Impact of microplastics on aquatic flora: Recent status, mechanisms of their toxicity and bioremediation strategies
This review examines how microplastics affect aquatic plants, from microscopic algae to larger vegetation, by physically blocking sunlight and pores and disrupting photosynthesis, reproduction, and nutrient uptake. Prolonged exposure triggers excessive production of harmful reactive oxygen species in plant cells, which can lead to cell death. The authors also highlight bioremediation approaches, including certain plants and microorganisms that can adsorb or break down microplastics by 25 to 80 percent in laboratory settings.
Microplastic pollution in terrestrial ecosystems: Global implications and sustainable solutions
