ClearReview of the toxic effect of microplastics on terrestrial and aquatic plants
This review summarizes research on how microplastics affect both terrestrial and aquatic plants, finding that their toxicity depends on the type, size, and surface chemistry of the plastic particles. Researchers found that seeds and root systems are particularly vulnerable to microplastic exposure, and that the harmful effects differ between land and water plants. The study also highlights that chemicals released from or adsorbed onto microplastics pose additional secondary risks to plant health.
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.
The threat of micro/nanoplastic to aquatic plants: current knowledge, gaps, and future perspectives
This review summarizes what is known about how micro- and nanoplastics affect aquatic plants, including how plants absorb these particles through roots and leaves and transport them internally. Exposure can alter plant growth, photosynthesis, and interactions with other organisms, though effects vary widely depending on plastic type and concentration. The authors highlight major research gaps and call for more studies on real-world conditions rather than controlled lab settings.
Effects of microplastics on freshwater and marine microalgae
This book chapter reviews the effects of microplastics on freshwater and marine microalgae, covering how different plastic types and sizes affect algal growth, photosynthesis, and reproduction. Microalgae form the base of aquatic food webs, so plastic-induced disruption to algal communities could have cascading effects throughout ecosystems.

Microplastics on the growth of plants and seed germination in aquatic and terrestrial ecosystems
This review examined the effects of microplastics on plant growth and seed germination in aquatic and terrestrial ecosystems, finding that microplastic presence can affect plant development through multiple mechanisms depending on polymer type, concentration, and the composition of the growing medium.
Adsorption, uptake and toxicity of micro- and nanoplastics: Effects on terrestrial plants and aquatic macrophytes
This review summarizes research on how micro- and nanoplastics interact with terrestrial plants and aquatic macrophytes, finding that many species can absorb or take up plastic particles. Both short-term and long-term plastic exposure triggered stress responses in plants, and since plants are at the base of food chains and a major part of the human diet, there is concern about plastics moving up through the food web. The findings suggest that plastic pollution could potentially affect plant productivity and broader ecosystem function.
Ecotoxicity of micro- and nanoplastics on aquatic algae: Facts, challenges, and future opportunities
This review provides a comprehensive assessment of how micro- and nanoplastics harm aquatic algae, which form the base of ocean and freshwater food chains. The toxic effects include reduced growth, oxidative stress, and disrupted photosynthesis, with nanoplastics generally causing more damage than larger particles. Since algae support the entire aquatic food web, their decline from plastic pollution could reduce the quality and safety of fish and shellfish consumed by people.
Effects of Microplastics on Higher Plants: A Review
This review examines how microplastics affect higher plants, covering impacts on seed germination, root growth, photosynthesis, and nutrient uptake, while highlighting the role of plastic type, size, and concentration in determining phytotoxicity.
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.
Assessing phytotoxicity of microplastics on aquatic plants using fluorescent microplastics
Researchers tested the effects of tiny fluorescent microplastics on three types of aquatic plants and found that two species showed significantly reduced biomass after three weeks of exposure. They confirmed through laser fluorescence detection that the plants took up the microplastic particles. The study provides early evidence that microplastics can be directly harmful to aquatic plant growth, an area that has received limited research attention.
Implication of microplastic toxicity on functioning of microalgae in aquatic system
This review examined how microplastics interact with and affect microalgae, which serve as primary producers in aquatic ecosystems. Researchers analyzed the toxic effects of both single and mixed plastic particles on microalgae cells, including impacts on photosynthesis, growth, and cellular function. The study highlights that microplastic toxicity to microalgae could have cascading effects throughout aquatic food webs.

Microplastic/nanoplastic toxicity in plants: an imminent concern
This review examines the growing body of research on how microplastics and nanoplastics affect terrestrial plants, from root uptake to changes in growth and gene expression. Researchers found that these particles can alter plant physiology and biochemistry at varying degrees depending on particle size and concentration.

This meta-analysis found that micro- and nanoplastics cause significant harm to aquatic plants, reducing their biomass and chlorophyll content through oxidative stress. Polyethylene was especially damaging, cutting plant biomass by over 42%. When plastic pollution harms the base of aquatic food chains, the effects can ripple upward through ecosystems that support both wildlife and human food sources.
Plants and microplastics: Growing impacts in the terrestrial environment
This review examines how microplastics affect plant growth and food crops, finding that exposure generally reduces plant size, chlorophyll content, and photosynthesis, though low concentrations can sometimes stimulate root growth. Plants can take up plastic particles smaller than 1 micrometer through their roots and move them to other tissues. These findings raise concerns that microplastics in soil, which can occur at higher levels than in water, could affect the health and nutritional quality of the food crops that people depend on.

This review examines how microplastics and nanoplastics affect photosynthetic organisms in both water and on land, including algae, aquatic plants, and terrestrial crops. Researchers found that smaller plastic particles and those with positive surface charges tend to be the most toxic, and that chemical additives leaching from plastics are a major source of harm. The study raises concerns that plastics can be absorbed by plants and potentially transferred up the food chain to consumers.
