ClearEcotoxicological 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.
A dosage-effect assessment of acute toxicology tests of microplastic exposure in filter-feeding fish
Researchers assessed the dose-dependent effects of polystyrene microplastics on silver carp, a filter-feeding fish, during a 48-hour exposure and recovery period. Low concentrations induced oxidative stress and gene upregulation in the intestine, with the fish able to recover after exposure ended. However, high concentrations caused significant gill and intestinal damage that persisted even after the microplastics were removed.
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.

Researchers exposed young crucian carp to polystyrene microplastics at different concentrations and found dose-dependent liver damage, with higher concentrations causing more severe tissue injury and weaker antioxidant defenses. The microplastics disrupted genes involved in detoxification and stress response in liver cells. Since crucian carp is a commonly consumed freshwater fish, these findings raise questions about whether microplastic-contaminated fish could affect the health of people who eat them.
Ecotoxicological Effects of Polystyrene Particle Mix (20, 200, and 430 µm) on Cyprinus carpio
Researchers exposed common carp to polystyrene microplastics of three different sizes in both short-term and long-term experiments, following standardized testing methods. While no deaths or acute effects occurred after 96 hours, the 75-day chronic exposure revealed changes in physiological markers and tissue-level effects. The study suggests that the real concern with microplastic exposure in fish lies in subtle, long-term biological changes rather than immediate toxic effects.

The microplastics accumulated in gills, stomachs, intestines, and hemolymph, causing persistent mitochondrial damage, oxidative stress, and gut microbiota imbalance that did not fully recover even after the exposure ended.
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.
Sub-chronic nanoplastic toxicity in Etroplus suratensis (Pisces, Cichilidae): Insights into tissue accumulation, stress and metabolic disruption
Researchers exposed pearl spot fish to polystyrene nanoplastics at different concentrations for 14 days and found that the particles accumulated in multiple organs with concentration-dependent distribution patterns. The nanoplastics caused elevated glucose and cholesterol levels, suppressed antioxidant defenses, and increased markers of oxidative damage and stress. Gene expression changes in stress response and growth-related genes suggest that nanoplastic exposure may impair both immune function and normal development in fish.

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.
