Effects of micro- and nanoplastics on aquatic ecosystems: Current research trends and perspectives
This review covers 83 studies on the distribution and toxic effects of micro- and nanoplastics in both marine and freshwater ecosystems worldwide. Researchers found that these tiny particles affected the growth, development, behavior, reproduction, and survival of a wide range of aquatic organisms. The paper identifies key research gaps and suggests future directions for understanding the full ecological impact of plastic pollution in aquatic environments.
Biological Effects and Implications of Micro- and Nanoplastics in the Aquatic Environment
This review summarizes what is known about the biological effects and implications of micro- and nanoplastics on aquatic organisms, covering a wide range of species from phytoplankton to fish. It highlights that while laboratory studies show harm at high concentrations, the effects at environmentally relevant levels are still poorly understood.
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.
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.
Nanoplastics impact on marine biota: A review
Researchers reviewed the emerging toxicological literature on nanoplastics in marine ecosystems, distinguishing primary nanoplastics (manufactured at nanoscale) from secondary nanoplastics (fragmented from larger debris), and summarizing how nanoscale size changes particle reactivity and bioavailability in ways that differ substantially from their macro- and microscale counterparts.
Environmental Impact of Microplastics in Aquatic Ecosystems: A Review of Current Research and Future Directions
This review examines microplastic pollution in aquatic ecosystems, covering chemical, biological, and ecological processes beyond simple physical contamination and identifying priority areas for future research directions.
Current understanding and challenges for aquatic primary producers in a world with rising micro- and nano-plastic levels
Researchers conducted a quantitative analysis of published studies on how micro- and nanoplastics affect aquatic primary producers like microalgae. They found that microplastics generally inhibited algal growth, but typically only at concentrations much higher than those currently found in the environment, with positively charged particles being the most toxic. The study highlights that the effects on photosynthesis and metabolism vary greatly depending on particle properties and algal species.
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.
Impact of Micro and Nano Plastics on Ocean Environment
This review examines the impacts of micro- and nanoplastics on ocean environments, covering their sources, fragmentation from larger plastic debris, effects on marine species across the food chain from plankton to fish, and implications for ocean ecosystem health.
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.
Micro/nano-plastics and microalgae in aquatic environment: Influence factor, interaction, and molecular mechanisms.
This review examined the interactions between micro/nanoplastics and microalgae in aquatic environments, summarizing how plastic particle size, surface chemistry, and co-pollutants influence algal toxicity through oxidative stress, photosynthesis inhibition, and gene expression changes.
Effects of microplastics on microalgae populations: A critical review
This critical review examines how microplastics affect microalgae populations, which are essential primary producers at the base of aquatic food webs. Researchers found that microplastics can reduce algal growth, impair photosynthesis, and cause oxidative stress, with effects varying by plastic type, size, and concentration. The study highlights that harm to microalgae from plastic pollution could have cascading effects throughout entire aquatic ecosystems.
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.

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.
