ClearA 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.
A systematic review of the effects of nanoplastics on fish
This systematic review examines how nanoplastics (extremely small plastic particles) affect fish, including their ability to cross biological barriers and accumulate in tissues. The findings are relevant to human health because fish are a major dietary protein source, and understanding how plastics move through aquatic food chains helps us assess our own exposure risks.
Microplastics in Fish and Shellfish – A Threat to Seafood Safety?
This review evaluated the current knowledge on microplastic contamination in fish and shellfish in relation to seafood safety. Researchers found that while microplastics are commonly detected in the gastrointestinal tracts of fish (which are typically not consumed), bivalves and small fish eaten whole may present a more direct route of human exposure, though the overall health risk from microplastics in seafood remains uncertain.
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.
Ingestion of nano/micro plastic particles by the mussel Mytilus coruscus is size dependent
Researchers investigated how the thick shell mussel Mytilus coruscus ingests plastic particles of different sizes, ranging from 70 nanometers to 100 micrometers. They found that smaller particles were ingested in greater quantities and accumulated primarily in the digestive tract, while particles also translocated to the mantle tissue over time. The study demonstrates that plastic particle ingestion by mussels is strongly size-dependent, with smaller particles posing a greater accumulation risk.
Effect of nanoplastics on fish health and performance: A review
Researchers reviewed studies on nanoplastics (particles smaller than 100 nm) in fish and found evidence of tissue accumulation, impaired locomotion and foraging, immune and growth disruption, altered lipid metabolism, and neurotoxicity, though mortality and developmental malformations had not yet been reported.
Characteristics of Microplastic in Commercial Aquatic Organisms
This review examined microplastic occurrence across multiple commercial aquatic species, compiling data on ingestion rates, particle characteristics, and potential risks to seafood safety. The authors identify fish, crustaceans, and bivalves as primary vectors of human dietary exposure to microplastics through seafood consumption.
Size-Dependent Uptake and Depuration of Nanoplastics in Tilapia (Oreochromis niloticus) and Distinct Intestinal Impacts
Researchers tracked how tilapia fish absorb and eliminate nanoplastics of two sizes (86 and 185 nanometers) and found that both accumulated most heavily in the intestine. Smaller nanoplastics caused more physical damage to the intestinal lining, while larger ones disrupted the gut microbiome more severely. Since tilapia is widely consumed worldwide, the finding that nanoplastics build up in fish tissue and damage their guts raises concerns about the safety of farmed fish as food.
Ingestion of Microplastics by Marine Animals
This review examines microplastic ingestion by marine animals, assessing how the small size and ubiquity of microplastics in oceans leads to widespread consumption across species, with effects ranging from physical gut blockage to chemical toxicity at organism and ecosystem levels.
Threats of Microplastic Pollution on Fishes and its Implications on Human Health (Review Article)
This review summarizes research from 2010 to 2023 on microplastic contamination in fish and its potential implications for human health. Researchers found that microplastics are ingested by fish across diverse aquatic environments, with particles accumulating in the gastrointestinal tract and other tissues. The study highlights concerns that microplastic-contaminated seafood may represent a pathway for human exposure to both the plastic particles and associated chemical pollutants.

This review examined the risks of marine micro- and nanoplastics to seafood safety and human health, detailing how plastic particles are ingested by marine organisms and transferred through the food chain to consumers.
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.
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.
Plastic contamination of the food chain: A threat to human health?
This review examines how microplastics and nanoplastics enter the human food chain through shellfish, inhalation, and other routes, and assesses what is known about their toxicity. The authors conclude that while larger microplastics appear to have low absorption and toxicity, nanoplastics may accumulate in tissues and potentially affect the nervous and reproductive systems, though effects in humans remain unproven.

It identifies chemical co-contamination and particle size as key modulators of toxicity.
The impact of nano/micro-plastics toxicity on seafood quality and human health: facts and gaps
This review examines the impact of nano- and microplastic contamination on seafood quality and human health. Researchers note that while microplastic absorption in fish is generally considered low, bioavailability depends on the physical and chemical properties of the particles, and prolonged exposure to high levels may be hazardous. The study highlights significant knowledge gaps around long-term exposure effects and calls for policy action on microplastic limits in food.
Impact of Microplastics on Aquatic Organisms and Human Health: A Review
This review examined the impacts of microplastics on aquatic organisms and human health, highlighting that microplastic size ranges mimic prey sizes ingested by aquatic organisms and that contaminated commercially important fish species transfer microplastics to human consumers. The authors synthesised evidence on ingestion pathways, toxicological effects, and human dietary exposure routes.
Fish size influences microplastic occurrence in target organs
Researchers examined whether fish body size affects microplastic occurrence in target organs, moving beyond gut content analysis to assess systemic tissue contamination. Larger fish contained more microplastics in their organs than smaller fish, suggesting size-dependent differences in cumulative lifetime exposure.
Microplastics and seafood: lower trophic organisms at highest risk of contamination
This systematic review summarizes existing research on microplastic contamination in commercially important seafood species. The findings show that organisms lower on the food chain, like shellfish and small fish, tend to accumulate the most microplastics. Since many people eat these organisms whole, including their digestive tracts, this represents a direct pathway for microplastics to enter the human diet.
Assessing toxicological risk of nanoplastics contaminants in food and feed from ingestion pathway to human diseases
This review examines how nanoplastics, which are tiny fragments smaller than 0.1 micrometers, enter the human food chain and may pose health risks. Evidence indicates that nanoplastics can cross biological membranes more easily than larger microplastics, potentially reaching organs and accumulating over time. The study highlights the need for better detection methods and risk assessments to understand the long-term health implications of nanoplastic ingestion through food and beverages.
