ClearA review of the neurobehavioural, physiological, and reproductive toxicity of microplastics in fishes
This review summarizes how microplastics cause a range of harmful effects in fish, including behavioral changes, brain and immune system damage, oxidative stress, and reproductive disruption through interference with hormone signaling. These findings are relevant to human health because many of the same biological pathways affected in fish also exist in humans, and people consume fish that have accumulated microplastics.
Microplastics stunt fish growth and alter behavior
A study of European perch larvae found that high levels of polystyrene microplastics inhibited hatching, stunted growth, and made fish more likely to be eaten by predators. These findings raised serious concern about microplastic impacts on fish populations and the marine food supply that humans depend on.
Toxic effects of polyethylene-microplastics on freshwater fish species: Implications for human health
This study reviews the toxic effects of polyethylene microplastics on freshwater fish species and the implications for human health, drawing on a body of existing literature on plastic pollution in aquatic ecosystems. The work synthesizes evidence of microplastic ingestion, bioaccumulation, and physiological effects in freshwater fish with relevance to human dietary exposure.
Assessment of dietary polyvinylchloride, polypropylene and polyethylene terephthalate exposure in Nile tilapia, Oreochromis niloticus: Bioaccumulation, and effects on behaviour, growth, hematology and histology
Nile tilapia fish fed three common types of microplastics (PVC, polypropylene, and PET) showed reduced growth, abnormal behavior, blood cell damage, and tissue damage in their gills, liver, and intestines. The harmful effects increased with higher doses of microplastics and varied by plastic type. Since tilapia is one of the most widely consumed fish globally, these findings raise concerns about the health of fish that may carry microplastic contamination to human diets.
Exposure to microplastics impairs fish's major behaviors. A novel threat to aquatic ecosystem
This review synthesises evidence on how microplastic exposure alters key behaviours in fish including feeding, reproduction, predator avoidance, and social interaction. It identifies neurological disruption, chemical co-toxicity, and gut effects as primary mechanisms, and highlights exposure to realistic environmental concentrations as an ongoing knowledge gap.
Toxicity of microplastics in fish: A short review
This short review summarizes current knowledge on microplastic occurrence in fish, covering sources and pathways of ingestion, impacts on fish physiology and behavior, and potential strategies for monitoring and reducing contamination.
Microplastics and behavioral changes in fish: an integrative review
This integrative review synthesizes the scientific literature on how microplastic exposure affects fish behavior, covering feeding, reproduction, predator avoidance, and social interactions. Exposure to microplastics consistently disrupted behavioral endpoints across fish species, with effects linked to oxidative stress, neurotoxicity, and endocrine disruption.
Ecotoxicological effects of low-density polyethylene microplastic on Heteropneustes fossilis: behavioral, hematological, biochemical, and histopathological impacts
Scientists exposed freshwater fish to tiny plastic particles (microplastics) from everyday items like plastic bags and found they caused serious health problems including blood disorders, organ damage, and weakened immune systems. The higher the amount of plastic particles, the worse the damage became to vital organs like gills, intestines, and liver. This matters because these same microplastics are found throughout our food chain and water supply, raising concerns about potential health risks for humans who consume contaminated fish and water.
Impacto de la ingesta de residuos plásticos en peces
This review summarizes research on how plastic waste affects fish through direct ingestion, exposure to contaminated water, and transfer through the food chain. Multiple studies consistently found physical injury, toxicity, and reproductive disruption across a range of fish species exposed to different plastic types and concentrations.
Ingestion of polyethylene microplastics impacts cichlid behaviour despite having low retention time
Researchers fed juvenile cichlid fish brine shrimp contaminated with polyethylene microplastics and observed significant behavioral changes, including altered activity and feeding patterns, even though the plastic particles passed through the fish quickly. The study suggests that even brief microplastic exposure can disrupt normal fish behavior, which could affect their survival in polluted waterways.
Toxicological consequences of microplastics pollution on aquatic Li Ving organisms: a review
This review examines the toxicological consequences of microplastic pollution on aquatic organisms, summarizing effects on growth, reproduction, oxidative stress, and endocrine function across fish, invertebrate, and algae model species.
Decreased growth and survival in small juvenile fish, after chronic exposure to environmentally relevant concentrations of microplastic
Researchers exposed juvenile glassfish to environmentally realistic concentrations of both virgin and harbor-collected microplastics for 95 days, finding that fish in plastic-fed groups grew significantly less in length, depth, and mass, and had lower survival probability than controls.
Developmental Polyethylene Microplastic Fiber Exposure Entails Subtle Reproductive Impacts in Juvenile Japanese Medaka (Oryzias latipes)
Japanese medaka fish exposed to environmentally relevant levels of polyethylene microplastic fibers throughout development showed subtle but measurable reproductive impacts including alterations in gonadal development. The findings suggest that chronic low-dose microplastic fiber exposure during early life may impair future reproductive capacity in fish.
Individual and combined effects of microplastics and diphenyl phthalate as plastic additives on male goldfish: A biochemical and physiological investigation
Male goldfish exposed to both microplastics and the plasticizer chemical DPP (diphenyl phthalate) together showed significant liver damage, disrupted fat and sugar metabolism, and hormonal imbalances including decreased testosterone and increased estrogen. The combined exposure was more harmful than either pollutant alone, demonstrating how microplastics and their chemical additives can work together to disrupt the endocrine system.
Effects of pristine or contaminated polyethylene microplastics on zebrafish development
Researchers examined the effects of both pristine and pollutant-contaminated polyethylene microplastics on zebrafish development through chronic exposure. The study assessed how microplastics, both alone and as carriers of adsorbed organic pollutants, affect developing fish. The findings provide new insights into how contaminated microplastics may create additional routes for toxic compounds to enter aquatic food webs.
Microplastic toxicity in fish: A potential review on sources, impacts, and solution
This review summarizes research on how microplastics affect fish health, covering sources of contamination, physical damage, hormonal disruption, and behavioral changes. Microplastics accumulate in fish tissues and can concentrate up the food chain, with potential toxic effects passing on to humans who eat contaminated seafood. The authors discuss possible solutions including better waste management, biodegradable alternatives, and advanced water treatment.
Ingestion and the toxicological effects of virgin polyethylene (PE) and PVC microplastics in commercial freshwater fish, Tilapia (Oreochromis niloticus)
Researchers exposed Nile tilapia to virgin polyethylene and PVC microplastics for 21 days, finding that both types caused behavioral changes and mortality, with PVC producing greater toxicity, reduced growth rates, and histological damage to gut and liver tissue.
Chronic feeding exposure to virgin and spiked microplastics disrupts essential biological functions in teleost fish
Researchers fed zebrafish and marine medaka environmentally relevant concentrations of virgin and chemically spiked polyethylene and PVC microplastics over four months. While classical biomarkers showed no changes, significant decreases in growth and disruptions to reproduction, gut integrity, and liver function were observed. The findings suggest that chronic dietary exposure to microplastics can disrupt essential biological functions in fish even without triggering traditional toxicity markers.
