ClearSubacute toxic effects of polyvinyl chloride microplastics (PVC-MPs) in juvenile common carp, Cyprinus carpio (Pisces: Cyprinidae)
Juvenile common carp exposed to polyvinyl chloride microplastics showed dose-dependent toxic effects including tissue damage, oxidative stress, and altered biochemical markers over a subacute exposure period. The results indicate that PVC microplastics are harmful to freshwater fish at ecologically relevant concentrations.
Polyvinyl chloride microplastics induce growth inhibition and oxidative stress in Cyprinus carpio var. larvae
Researchers exposed carp larvae to polyvinyl chloride microplastics in their diet for 30 and 60 days at various concentrations. The microplastics significantly inhibited growth and weight gain while causing oxidative stress, altered antioxidant enzyme activities, and changes in gene expression in the liver. Histological examination revealed tissue damage including vacuolation in the liver under higher exposure concentrations.
Dietary administration of PVC and PE microplastics produces histological damage, oxidative stress and immunoregulation in European sea bass (Dicentrarchus labrax L.)
Researchers fed European sea bass diets containing PVC and polyethylene microplastics for three weeks and examined the effects on their organs and immune systems. They found significant tissue damage in the liver and intestine, along with signs of oxidative stress and altered immune function. The study suggests that even short-to-medium-term microplastic ingestion can compromise fish health, with longer exposures potentially leading to irreversible organ damage.
Polyvinyl chloride microplastics induce changes in gene expression and organ histology along the HPG axis in Cyprinus carpio var. larvae
Researchers exposed common carp larvae to different concentrations of PVC microplastics in their diet for 60 days and examined effects on their reproductive system. The study found that microplastic exposure significantly reduced gonad development, altered sex hormone levels, and changed the expression of genes related to reproduction and cell death along the hypothalamic-pituitary-gonadal axis. These findings suggest that PVC microplastics may negatively impact fish reproductive health by disrupting hormonal signaling and gonadal development.
Differential modulation of oxidative stress, antioxidant defense, histomorphology, ion-regulation and growth marker gene expression in goldfish (Carassius auratus) following exposure to different dose of virgin microplastics
Goldfish exposed to two doses of virgin PVC microplastics for four days showed dose-dependent gill, liver, and intestinal tissue damage, elevated oxidative stress markers, disrupted antioxidant enzyme activity, and altered expression of ion-regulation and growth marker genes.
Exposure to polypropylene microplastics via diet and water induces oxidative stress in Cyprinus carpio
Researchers fed carp fish polypropylene microplastics through both food and water and found that exposure caused oxidative stress in the liver, gills, and intestines. The damage was dose-dependent, with higher microplastic concentrations causing more harm to the fish's antioxidant defense systems. Since carp is a widely consumed fish, these findings raise questions about whether microplastics in aquaculture could affect the safety of fish as human food.
Dietary exposure to polyvinyl chloride microparticles induced oxidative stress and hepatic damage in Clarias gariepinus (Burchell, 1822)
Catfish (Clarias gariepinus) fed PVC microparticle-spiked diets at three inclusion levels for 45 days showed dose-dependent liver damage, elevated antioxidant enzyme activity, and altered serum biochemistry, indicating that dietary PVC microplastic ingestion causes measurable hepatotoxicity.
Adverse effects of polystyrene microplastics in the freshwater commercial fish, grass carp (Ctenopharyngodon idella): Emphasis on physiological response and intestinal microbiome
Researchers exposed grass carp to different sizes and concentrations of polystyrene microplastics for up to 14 days, followed by a depuration period, and assessed physiological and intestinal microbiome effects. The study found that microplastics caused histological damage, oxidative stress, and shifts in gut microbial communities, with smaller particles and higher concentrations producing more severe effects.
Ecotoxicological Effects of Polystyrene Particles on Cyprinus carpio: A Laboratory Assessment
Researchers exposed common carp (Cyprinus carpio) to polystyrene particles in a controlled laboratory setting, measuring survival, growth, histological damage, and oxidative stress markers over a 30-day period. Exposed fish showed liver and gill tissue damage alongside elevated oxidative stress enzymes, demonstrating that polystyrene microplastics are harmful to freshwater fish at tested concentrations.
Histopathological damage and stress‐ and immune‐related genes' expression in the intestine of common carp, Cyprinus carpio exposed to copper and polyvinyl chloride microparticle
Researchers examined the combined effects of copper and PVC microplastics on common carp intestines, finding that co-exposure caused greater histopathological damage and altered stress- and immune-related gene expression compared to either contaminant alone.
Toxic effects of microplastic (polyethylene) exposure: Bioaccumulation, hematological parameters and antioxidant responses in crucian carp, Carassius carassius
Researchers exposed crucian carp to polyethylene microplastics at various concentrations and found that the particles accumulated in tissues including gills, gut, and liver. The microplastics altered blood cell counts and disrupted the fish's antioxidant defense system in a dose-dependent manner. The study suggests that even common polyethylene microplastics can cause measurable biological harm in freshwater fish.
Effect of Polystyrene Microplastic Exposure on Individual, Tissue, and Gene Expression in Juvenile Crucian Carp (Carassius auratus)
Juvenile crucian carp were exposed to polystyrene microplastics at different concentrations, and researchers found that the particles accumulated mainly in the intestines and gills. The study suggests that microplastic exposure caused tissue damage to multiple organs and altered gene expression, with higher concentrations generally leading to more severe effects.
Deleterious Effects of Polypropylene Microplastic Ingestion in Nile Tilapia (Oreochromis niloticus)
Researchers fed Nile tilapia daily doses of polypropylene microplastics for 30 days and observed significant health effects including changes in blood cell counts, altered gut bacteria, and tissue damage to the intestines and liver. The higher dose group showed more pronounced effects, including elevated inflammatory markers and signs of oxidative stress. The study provides evidence that chronic ingestion of microplastics commonly found in aquatic environments can cause meaningful harm to a widely consumed fish species.
Investigation of the impact caused by different sizes of polyethylene plastics (nano, micro, and macro) in common carp juveniles, Cyprinus carpio L., using multi-biomarkers.
Common carp juveniles exposed to polyethylene plastics of three different sizes (nano, micro, and macro) all showed tissue damage, oxidative stress, and immune disruption, with nanoparticles causing the most severe effects. The size-dependent toxicity pattern suggests that as larger environmental plastics break down into smaller particles, their potential to harm fish — and ultimately people who eat them — may increase.
Polystyrene microplastics induce endoplasmic reticulum stress, apoptosis and inflammation by disrupting the gut microbiota in carp intestines
Researchers fed carp polystyrene microplastics and found that the particles disrupted their gut bacteria, killing off beneficial species and promoting those linked to diseases. The microplastics triggered a stress response in intestinal cells that led to inflammation, cell death, and tissue damage. Since carp is a widely eaten fish, these gut health effects raise questions about how microplastics in aquatic environments could affect the safety of fish that humans consume.
Polystyrene microplastics exposure in freshwater fish, Labeo rohita: evaluation of physiology and histopathology
Researchers fed freshwater fish varying levels of polystyrene microplastics for 90 days and found dose-dependent damage to blood health, growth, and organ tissues. Higher microplastic concentrations caused more severe harm to the liver, kidneys, gills, and intestines. The study highlights that microplastics in freshwater systems can accumulate in fish and cause significant health problems, raising concerns about food safety for communities that rely on freshwater fish.
Microplastics induced histopathological lesions in some tissues of tilapia (Oreochromis niloticus) early juveniles
Researchers exposed young tilapia fish to different concentrations of microplastics for 15 days to study effects on their organs. The study found damage across multiple tissues including the kidney, liver, pancreas, gills, and muscles, with effects ranging from inflammation and cell death to structural deformation. These findings suggest that microplastic exposure can cause widespread organ damage in fish even at relatively low concentrations.
