ClearEffects of nanoplastics on microalgae and their trophic transfer along the food chain: recent advances and perspectives
This review summarized evidence on how nanoplastics affect microalgae — including growth inhibition, oxidative stress, and altered photosynthesis — and examined trophic transfer of nanoplastics up the food chain, finding that toxicity depended on NP concentration, size, and surface charge.
Effect and mechanism of microplastics exposure against microalgae: Photosynthesis and oxidative stress
Meta-analysis of 55 studies (835 endpoints) found that microplastics reduce chlorophyll-a content and hinder electron transfer in microalgae photosynthetic systems, causing oxidative stress damage. Effects were concentration- and size-dependent, with freshwater microalgae more susceptible than marine species.
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.
Evaluating physiological responses of microalgae towards environmentally coexisting microplastics: A meta-analysis
A meta-analysis of 52 studies found that microplastics inhibit microalgal growth and photosynthesis and induce oxidative damage, though microalgae can recover over time. Cyanobacteria are more vulnerable than green algae, and the relative size of microplastics to algal cells governs the mechanism of impact, while aged versus pristine microplastics have opposite effects on extracellular polymeric substance and microcystin production.
Micro/nanoplastic-induced stress in microalgae: Latest laboratory evidence and knowledge gaps
This review compiled laboratory evidence on how micro- and nanoplastics stress microalgae — the base of aquatic food webs — covering effects on photosynthesis, growth, oxidative stress, and toxin production. The authors identify key knowledge gaps including environmentally realistic concentrations and combined contaminant effects.
Toxic Effects of Microplastics on Culture Scenedesmus quadricauda: Interactions between Microplastics and Algae
Researchers found that microplastics from multiple polymer types inhibit growth of the freshwater alga Scenedesmus quadricauda and induce oxidative stress, with toxicity varying by polymer type, particle size, and concentration.
Microplastic interactions with freshwater microalgae: Hetero-aggregation and changes in plastic density appear strongly dependent on polymer type
Researchers studied interactions between microplastics and freshwater microalgae, finding that microplastics can physically attach to algal cells to form hetero-aggregates, altering both particle behavior and algal physiology.
Research advances on impacts micro/nanoplastics and their carried pollutants on algae in aquatic ecosystems: A review
This review examines how micro- and nanoplastics harm algae, which are the foundation of aquatic food chains, by slowing growth, reducing photosynthesis, and damaging cells. The effects are worse when microplastics carry other pollutants on their surfaces, creating a combined toxic effect. Since algae support the entire aquatic food web, damage to these organisms can ripple upward through fish and shellfish to affect the safety of seafood consumed by humans.
A critical review of interactions between microplastics, microalgae and aquatic ecosystem function
This review of microplastic-microalgae interactions found that microplastics form distinct epiplastic algal communities that differ from surrounding water communities, and that the interactions are bidirectional — MP properties affect algal physiology while algal surface coatings alter MP behavior and fate.
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.
Microalgae–microplastics interactions at environmentally relevant concentrations: Implications toward ecology, bioeconomy, and UN SDGs
This study investigated how microalgae interact with microplastics at environmentally relevant concentrations, examining growth inhibition, aggregation, and photosynthetic effects, with implications for aquatic ecosystem function and the feasibility of microalgae-based bioremediation.
Distribution of Microplastics and Nanoplastics in Aquatic Ecosystems and Their Impacts on Aquatic Organisms, with Emphasis on Microalgae
This review covers the distribution of microplastics and nanoplastics in aquatic ecosystems and their impacts on aquatic organisms from bacteria to fish, with a focus on effects on microalgae as primary producers. The authors highlight that nanoplastics may be more biologically active than microplastics due to their size and surface reactivity, warranting greater research attention.
Microplastics – An emerging contaminants for algae. Critical review and perspectives
This review examines how microplastics and nanoplastics affect algae, which are the foundation of aquatic food chains. Microplastics can reduce algae growth, disrupt photosynthesis, and cause oxidative stress, with smaller nanoplastics being more harmful. Since algae are at the base of the food web, damage to them can ripple through ecosystems and ultimately affect the seafood that humans consume.
Meta-analysis for systematic review of global micro/nano-plastics contamination versus various freshwater microalgae: Toxicological effect patterns, taxon-specific response, and potential eco-risks
A meta-analysis of 1,071 observations found that nanoplastics cause more severe cell membrane damage than microplastics, while microplastics more strongly inhibit photosynthesis in freshwater microalgae. Among polymer types, polyamide caused the highest growth inhibition, polystyrene induced the most toxin release, and diatoms were the most sensitive algal group while cyanobacteria showed exceptional resilience.
The Growth Inhibition of Polyethylene Nanoplastics on the Bait-Microalgae Isochrysis galbana Based on the Transcriptome Analysis
Researchers found that polyethylene nanoplastics (50 nm) significantly inhibited growth and reduced chlorophyll in the bait microalga Isochrysis galbana through oxidative stress and disrupted gene expression, while larger microplastics had no significant impact.
Recent Advances in Micro-/Nanoplastic (MNPs) Removal by Microalgae and Possible Integrated Routes of Energy Recovery
This review examined the interactions between micro- and nanoplastics and microalgae, covering how microalgae are affected by plastic particles and how they can in turn be used to remove plastics from aquatic environments. The authors identify microalgae-based systems as promising tools for combined plastic removal and biomass production.

This meta-analysis evaluated how microplastic characteristics such as polymer type, size, shape, and concentration influence algal growth, finding that effects range from inhibition to enhancement depending on multiple interacting factors.
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.
