ClearImpact 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.
The Environmental Impacts of Nanoplastics in Marine Ecosystems
This review examined how nanoplastics—generated by degradation of larger plastics—penetrate biological barriers, accumulate in tissues, contribute to biomagnification, and disrupt marine food chains, highlighting their distinct ecotoxicological mechanisms compared to larger microplastics.
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.
Nano-Scale Plastic Pollution in the Marine Species: A Review
This review summarizes research on nano-scale plastic pollution in marine species, covering how nanoplastics are produced from larger plastics, how they enter organisms, and the toxic effects they cause in marine life. Because of their tiny size, nanoplastics can penetrate cells and tissues that larger microplastics cannot reach.
The toxicity of nanoplastics to marine organisms
This collection assesses the current knowledge on the toxicity of nanoplastics to marine organisms, examining both physical and chemical effects of these tiny plastic fragments that are smaller than microplastics. The monograph identifies the most pressing research gaps for understanding how nanoplastics affect marine ecosystems.
Impact of Nanoplastics on Marine Life: A Review
This review summarizes current knowledge about the effects of nanoplastics on marine organisms, including impacts on feeding, reproduction, growth, and cellular-level toxicity. Evidence indicates that nanoplastics can be more harmful than larger microplastics due to their ability to cross biological barriers and accumulate in tissues, though more research is needed on real-world exposure levels.
Toxicological review of micro- and nano-plastics in aquatic environments: Risks to ecosystems, food web dynamics and human health.
This review synthesized evidence on the toxicological effects of micro- and nanoplastics in aquatic ecosystems, covering risks to individual organisms, disruptions to food web dynamics, and pathways through which plastic exposure poses risks to human health via seafood consumption.
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.
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.
The scientific basis for addressing marine micro- and nanoplastic pollution: Informing effective monitoring and remediation frameworks
This review synthesizes the scientific basis for monitoring and remediating marine micro- and nanoplastic pollution, covering detection technologies, ecotoxicological effects across the food web, and the specific challenges nanoplastics pose due to their nanoscale properties.
Micro Plastics in The Marine Environment: A Review of Their Effects on Marine Organisms and Ecosystems
This review examines the effects of microplastics on marine organisms and ecosystems, summarizing evidence for MP ingestion across trophic levels, physical and chemical harm to marine life, and the pathways through which marine MP pollution threatens biodiversity and fisheries.
Microplastics in the marine environment - A threat to marine biota?
This review examines the sources, quantities, and effects of microplastics in marine environments to assess whether they pose a genuine threat to marine life. Microplastics are found everywhere from Arctic to Antarctic waters, with the smallest fragments being the most concerning because they are available to a wider range of organisms and have more surface area to carry toxic chemicals.
Environmental Toxicity of Emerging Micro and Nanoplastics
This review examines the environmental toxicity of emerging micro- and nanoplastics, covering their sources, degradation pathways, ecological impacts on organisms, and the need for standardized risk assessment frameworks.

This review synthesized the state of knowledge on microplastics as marine contaminants, covering their sources, pathways, distribution, biological uptake, and potential ecological and toxicological effects.
Toxicity of microplastics in the marine environment.
This review chapter provides a broad and updated overview of microplastic ecotoxicology in marine environments, covering effects from the biochemical level through population and ecosystem scales. Evidence reviewed demonstrates that microplastics can act as physical hazards and chemical vectors affecting marine biodiversity across multiple trophic levels.
Micro- and nano-plastics in marine environment: Source, distribution and threats — A review
This review examines the sources, distribution, and threats of micro- and nanoplastics in the marine environment. Researchers found that microplastics are nearly ubiquitous in ocean ecosystems, causing harm to marine animals ranging from malnutrition to chemical poisoning. The study also highlights that nanoplastics can penetrate biological barriers, including the gastrointestinal and blood-brain barriers, and accumulate in vital organs.
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.
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.
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.

Nanoplastics and marine organisms: What has been studied?
Researchers reviewed published data on nanoplastic toxicity to marine organisms, finding evidence of harmful effects ranging from reproductive disruption to death across multiple phyla and noting that nanoplastics' small size makes them prone to bioaccumulation — while emphasizing that no standardized detection methods or protective regulations yet exist.
