ClearNano-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 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.
An overview of the effects of nanoplastics on marine organisms
This review summarizes current knowledge about how nanoplastics affect marine organisms, from plankton to fish. Researchers highlight that these extremely small plastic particles are difficult to detect and measure, meaning their true environmental presence is likely underestimated. The study warns that the effects of nanoplastics on marine life could indirectly impact human health through the seafood supply chain.
Effects of Nanoplastics on Aquatic Organisms
This review summarizes how nanoplastics — plastic particles smaller than 1 micrometer — affect aquatic organisms, highlighting their ability to penetrate cell membranes, accumulate inside organisms, and cause oxidative stress and reproductive harm.
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.
Biological Effects of Microplastics: A Review.
Researchers reviewed how microplastics harm a wide range of living things, finding they cause physical damage, inflammation, oxidative stress, and reproductive problems in aquatic animals, while also carrying toxic chemicals and dangerous bacteria into organisms. Major gaps remain in understanding the effects of long-term low-dose exposure and the risks posed by even tinier nanoplastics.
Ecotoxicological Impacts of Micro and Nanoplastics on Marine Fauna
This review examines the ecotoxicological impacts of micro- and nanoplastics on marine fauna, detailing how these particles enter food chains through ingestion, accumulate across trophic levels, and cause physical and chemical harm including oxidative stress, inflammation, reproductive disruption, and mortality. The authors highlight the compounding threat when plastics act as vectors for adsorbed pollutants.
Impact of micro- and nano-plastics on marine organisms under environmentally relevant conditions
This review summarized the impacts of micro- and nanoplastics on marine organisms including microalgae, crustaceans, snails, and fish at environmentally realistic concentrations. Researchers found that while some species showed tolerance at low concentrations, chronic exposure to nanoplastics in particular caused oxidative stress and behavioral changes. The study emphasizes that more research using real-world concentration levels is needed to accurately assess the risks microplastics pose to ocean life.
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.
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.
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.
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.
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.
Recent advances in toxicological research and potential health impact of microplastics and nanoplastics in vivo
This review summarizes the growing body of research on how micro- and nanoplastics affect living organisms, covering impacts from physical tissue damage and gut disruption to reproductive harm and immune system interference. Researchers found that these tiny particles can also act as carriers for heavy metals, toxic chemicals, and pathogens, potentially amplifying their harmful effects. The evidence indicates that microplastics may move up the food chain and ultimately reach humans, though the full extent of health risks remains under investigation.
Feasting on microplastics: ingestion by and effects on marine organisms
This review synthesizes experimental studies on microplastic ingestion and effects across a wide range of marine organisms, finding evidence of physical harm, reproductive effects, and reduced feeding in multiple taxa. The paper provides a comprehensive overview of the biological consequences of microplastic ingestion and identifies key knowledge gaps for future research.
Toxicity of nanoplastics to aquatic organisms: Genotoxicity, cytotoxicity, individual level and beyond individual level
This review examines the toxic effects of nanoplastics on aquatic organisms across multiple levels of the food chain, from bacteria and algae to fish. Researchers found that nanoplastics can cause cell damage, genetic harm, and reproductive problems, with toxicity influenced by particle size, concentration, and surface properties. The study also highlights how nanoplastic effects on individual organisms can cascade to disrupt broader ecosystem dynamics.
Biological Effects and Implications of Micro- and Nanoplastics in the Aquatic Environment

A Latest Review on Micro- and Nanoplastics in the Aquatic Environment: The Comparative Impact of Size on Environmental Behavior and Toxic Effect
This review compares how micro-sized and nano-sized plastic particles behave differently in water environments and affect aquatic organisms. Smaller nanoplastics are generally more harmful because they can cross biological barriers, enter cells, and accumulate in tissues more readily than larger microplastics. The size-dependent differences in toxicity highlighted in this review are important for understanding which plastic particles pose the greatest risk to human health through contaminated water and seafood.
[Toxicology of Nanoplastics to Aquatic and Terrestrial Organism: A Critical Review].
This review examines the toxicological effects of nanoplastics on aquatic and terrestrial organisms, noting that the vast surface area of nanoplastics enables them to carry environmental pollutants into organisms. Researchers describe how nanoplastics accumulate in organs and can transfer to offspring, potentially harming subsequent generations. The study highlights the need for further research on the health threats posed by nanoplastics at environmentally relevant concentrations.
