Global analysis of the adverse effects of micro- and nanoplastics on intestinal health and microbiota of fish
This large-scale analysis combined data from 118 studies to assess how micro- and nanoplastics affect fish gut health. The results show that these particles generally damage the intestinal lining, weaken immune defenses, and disrupt digestive function in fish. Younger fish and certain plastic types like PVC caused the most harm, highlighting that the specific characteristics of the plastic particles matter for understanding their toxicity.
Effects of microplastics in freshwater fishes health and the implications for human health
This review examines how microplastics affect the health of freshwater fish, which are a major protein source for billions of people. Fish ingest microplastics that accumulate in their guts, gills, and tissues, leading to inflammation, oxidative stress, and disrupted growth. Since microplastics in fish tissue can transfer to humans through the food chain, this is relevant to both ecosystem and human health.
A fishy gut feeling – current knowledge on gut microbiota in teleosts
This review summarizes what scientists know about the community of bacteria living in fish guts and how diet, environmental conditions, and pollutants shape that community. Microplastics and other pollutants can disrupt the gut microbiome in fish, harming their immune function and overall health. Since fish are a major food source for humans, understanding these effects matters for food safety.
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.
Micro/nano-plastics cause neurobehavioral toxicity in discus fish (Symphysodon aequifasciatus): Insight from brain-gut-microbiota axis
Researchers exposed juvenile discus fish to microfibers and nanoplastics and found that both types caused neurobehavioral problems, but through different mechanisms involving the brain-gut-microbiota axis. Nanoplastics weakened swimming and predatory abilities, while microfibers reduced growth, and both disrupted gut microbial communities that influence brain function. The study provides the first evidence linking microplastic-induced gut microbiome changes to neurological effects in fish through the gut-brain connection.
Ecotoxicological impacts of microplastics to gut microbiota: Response mechanism, challenges and environmental sustainability-A review
This review summarizes how microplastics affect gut bacteria in fish, mice, and earthworms after being swallowed. Microplastics can change the balance of gut microbes and reduce their helpful functions, leading to digestive problems, slower growth, and weakened immunity. Since humans are exposed to microplastics through food and water, these findings raise concerns that our own gut health could be similarly affected.
Global meta‐analysis reveals diverse effects of microplastics on freshwater and marine fishes
This systematic review and meta-analysis examines the effects of microplastics on fish in both freshwater and ocean environments. The findings show that microplastics reduce feeding, impair digestion, slow growth, and weaken immune function in fish, which is concerning because contaminated fish are a major food source for people worldwide.
The ant that may well destroy a whole dam: a systematic review of the health implication of nanoplastics/microplastics through gut microbiota
This systematic review summarizes existing research on how nanoplastics and microplastics disrupt gut bacteria in various organisms. The findings show that plastic particle exposure consistently alters gut microbiome composition, which in turn affects the host's immune function, metabolism, and overall health. These gut bacteria changes may be a key pathway through which microplastics harm human health.
Microbiome Composition and Function in Aquatic Vertebrates: Small Organisms Making Big Impacts on Aquatic Animal Health
This review examines how microbiomes (communities of microorganisms) function in fish and marine mammals, and how environmental stressors like microplastics can disrupt them. Microplastics in water can alter the natural balance of beneficial microbes in aquatic animals, potentially affecting their health and the safety of seafood. Understanding these disruptions matters because changes in fish microbiomes could affect the quality and safety of the fish that end up on our plates.
Microplastics bioaccumulation in fish: Its potential toxic effects on hematology, immune response, neurotoxicity, oxidative stress, growth, and reproductive dysfunction
This review finds that microplastics accumulate primarily in the guts and gills of fish before spreading to other tissues through the bloodstream, causing a cascade of harmful effects including blood changes, immune suppression, nerve damage, and reproductive problems. The severity of harm depends on the size and dose of particles and how long the fish are exposed, with implications for the safety of fish consumed by humans.

Microplastics in Fish and Fishery Products and Risks for Human Health: A Review
This review summarizes existing research on microplastic contamination in fish and seafood products and the associated human health risks. Microplastics found in fish can carry harmful chemicals and pathogens, and once eaten by humans, they may cause oxidative stress and move from the gut to other tissues. The review highlights seafood as a major dietary source of microplastic exposure and calls for better monitoring and risk assessment.
Immunotoxicity of microplastics in fish
This review examines how microplastics damage the immune systems of fish, from harming their gills and organs to disrupting immune cell signaling and gene expression. Over time, microplastic exposure weakens fish immunity by killing immune cells and reducing their ability to fight off infections, with implications for the broader food chain that connects aquatic life to human diets.
Low particle concentrations of nanoplastics impair the gut health of medaka
Researchers exposed Japanese medaka fish to low concentrations of nanoplastics for three months and observed significant damage to gut health, including tissue injury, impaired digestive enzymes, weakened immunity, and disrupted gut bacteria. Even at particle concentrations considered environmentally realistic, the nanoplastics caused measurable harm and increased mortality. The study suggests that long-term exposure to low levels of nanoplastics may pose greater risks to fish health than previously assumed.
