ClearEnvironmental fate, toxicity and risk management strategies of nanoplastics in the environment: Current status and future perspectives
This review provides a comprehensive look at nanoplastics -- tiny plastic particles smaller than one micrometer -- covering their environmental fate, toxic effects on organisms, and potential risks to ecosystems. Researchers found that nanoplastics can carry other pollutants like heavy metals and even serve as habitats for bacteria and viruses. The study calls for more research across all environmental compartments, including soil, air, and groundwater, to fully understand the scope of nanoplastic contamination.
A critical review on nanoplastics and its future perspectives in the marine environment
This review provides a comprehensive look at nanoplastics, plastic particles smaller than one micrometer, and their fate in marine environments. Researchers found that nanoplastics can originate from the breakdown of larger plastic debris and may carry harmful chemical additives and absorbed pollutants on their surfaces. The evidence indicates that due to their extremely small size, nanoplastics can cross biological barriers and accumulate in marine organisms, raising concerns about food chain contamination.
Nanoscale plastic pollution: sources, identification and potential mitigation
This review examines the sources, environmental fate, and potential mitigation strategies for nanoscale plastic pollution, tracing the accumulation of plastic particles from millimetre to nanometre scales over decades. It highlights key knowledge gaps and emerging approaches for reducing nanoplastic contamination in ecosystems.
Nanoplastics: Emerging Threat in Global Plastic Pollution
This review examines nanoplastics as an emerging global threat within the broader plastic pollution crisis, discussing their sources, environmental distribution, and potential ecological and human health risks as a distinct concern from larger microplastic particles.
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.
Nano-plastics and their analytical characterisation and fate in the marine environment: From source to sea
Researchers reviewed the sources, environmental fate, organism interactions, and analytical detection methods for nano-sized plastic polymers in the marine environment, concluding that nanoplastics pose the greatest ecological risk among plastic size fractions and that standardized analytical protocols for nanoplastic characterization are urgently needed.
Critical gaps in nanoplastics research and their connection to risk assessment
This paper identifies critical knowledge gaps in nanoplastics research and explains why they matter for assessing health and environmental risks. Nanoplastics are harder to detect and measure than larger microplastics, meaning current pollution estimates likely undercount total plastic contamination. The authors call for better detection methods and standardized research approaches to understand the true scope of nanoplastic exposure.
Nanoplastics in the Aquatic Environment. Critical Review
This critical review synthesized the emerging science on nanoplastics in aquatic environments, covering detection challenges, sources, behavior, and toxicological evidence, and identifying major gaps in knowledge about nanoplastic-specific risks.
New insights in to the environmental behavior and ecological toxicity of microplastics
This review provides new insights into how microplastics behave in the environment and their toxic effects on living organisms. Microplastics can absorb and carry other pollutants, making them more dangerous than the plastic alone, and their effects vary based on size, shape, and chemical composition. The review highlights that smaller particles, especially nanoplastics, pose the greatest risk because they can cross biological barriers and enter cells.
Nanoplastics in the Environment
This chapter reviews the emerging concern about nanoplastics — plastic particles smaller than 1 micrometer — which are even harder to detect and may have more pervasive biological effects than larger microplastics. Current analytical challenges make nanoplastics difficult to quantify in the environment, leaving significant knowledge gaps.
Nanoplastics in water
This paper examines the presence and behavior of nanoplastics, extremely small plastic particles, in water environments. Understanding how these particles move through and persist in water is important for assessing potential risks to aquatic ecosystems and human health.
Nanoparticles in the Environment and Nanotoxicology
This review examines the environmental fate and toxicological risks of nanomaterials, including engineered nanoparticles and microplastics/nanoplastics, as these materials are increasingly released into ecosystems. The paper surveys current understanding of nanotoxicology and highlights the potential risks that nanoparticle contamination poses to both ecological and human health.
Environmental Impacts of Microplastics and Nanoplastics: A Current Overview
This review examined the environmental impacts of microplastics and nanoplastics across ecosystems, highlighting that these tiny particles behave differently from larger plastic debris and can absorb and transport toxic chemicals. Researchers found evidence that these particles transfer through food chains from lower organisms to higher animals, including humans. The study also explored natural biodegradation processes and current efforts to reduce plastic pollution in the environment.

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.

Environmental Fate and Ecological Risk of Micro- and Nanoplastics across Terrestrial and Aquatic Ecosystems
Scientists reviewed existing research on tiny plastic particles (microplastics and nanoplastics) and found they're spreading throughout soil, rivers, and oceans, where animals eat them and pass them up the food chain. These plastic particles cause stress and health problems in wildlife, but researchers still don't fully understand the long-term effects or how much exposure is dangerous. This matters because these same plastic particles can end up in our food and water, but we need better research methods to understand the real risks to human health.
Nanoplastics in aquatic systems - are they more hazardous than microplastics?
This review evaluates whether nanoplastics — plastic particles smaller than 1000 nm — are more hazardous than microplastics, examining current evidence on their environmental concentrations, behavior, and toxicity. It concludes that nanoplastics pose distinct concerns due to greater bioavailability and cellular uptake potential, while noting that adequate standard detection methods do not yet exist.
Nanoplastics in focus: Exploring interdisciplinary approaches and future directions
This perspective paper highlights major gaps in nanoplastic research, arguing that studying nanoplastics as if they behave the same as microplastics misses important differences.
