Nanoplastics in aquatic environments: Origin, separation and characterization: Review
This review covers the origins, separation methods, and characterization of nanoplastics in aquatic environments. Nanoplastics (1–100 nm) are particularly concerning because their tiny size gives them a large surface area for adsorbing pollutants and allows them to penetrate biological barriers more easily than larger microplastics.

Review on impacts of micro- and nano-plastic on aquatic ecosystems and mitigation strategies
This review examines the environmental fate, ecological impacts, and remediation strategies for microplastics and nanoplastics in aquatic ecosystems. Researchers highlight that microbial remediation shows particular promise for breaking down these pollutants, while many nations are adopting regulations to limit plastic contamination of waterways. The study suggests that integrating approaches from nanoscience, microbial ecology, and remediation technologies is needed to address this growing environmental challenge.
Characterization, occurrence, environmental behaviors, and risks of nanoplastics in the aquatic environment: Current status and future perspectives
This review characterized the occurrence, environmental behavior, and toxicity of nanoplastics in aquatic systems, noting that their small size gives them unique properties — including higher surface reactivity and greater bioavailability — that make them potentially more hazardous than larger microplastics, while also harder to detect.
Plastics and Micro/Nano-Plastics (MNPs) in the Environment: Occurrence, Impact, and Toxicity
This review provides a broad overview of how plastics break down into micro- and nanoplastics in soil, water, and air, and how these tiny particles are taken up by plants, animals, and humans. As plastics age in the environment, they become more reactive and potentially more toxic. The paper discusses how these particles enter the body, where they accumulate, and the toxic effects observed in studies so far.
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.
Microplastics and Nanoplastics in Aquatic Environment
This review examines the origins, transport pathways, and toxic impacts of microplastics and nanoplastics in aquatic environments, tracing debris from diverse land-based and marine sources. Researchers found that plastic fragmentation produces ubiquitous micro- and nano-scale particles throughout ocean systems, with documented toxicity to marine organisms and potential risks to human consumers of seafood.
A review on occurrence, characteristics, toxicology and treatment of nanoplastic waste in the environment
This review summarizes the current understanding of nanoplastic pollution, including sources, occurrence in water, soil, and air, and potential toxicity to aquatic and terrestrial organisms. The study highlights major gaps in analytical methods for detecting nanoplastics and calls for more research on their environmental fate and health effects.
Emergence of nanoplastics in the aquatic environment and possible impacts on aquatic organisms
This review summarizes current knowledge on nanoplastics in aquatic environments, finding them present in seas, rivers, and nature reserves across multiple continents at measurable levels.
