Hepatic multi-level responses to polyethylene microplastics in Lateolabrax maculatus: Insights from transcriptomics, antioxidant enzyme activity, and histopathology
Researchers exposed spotted sea bass to diets containing polyethylene microplastics for 45 days and found multiple levels of liver damage, including altered gene expression, reduced antioxidant enzyme activity, and visible tissue changes. A subsequent depuration period showed partial but incomplete recovery. The study suggests that chronic microplastic exposure through contaminated feed may pose significant risks to liver health in commercially farmed fish species.
Nanoplastics and chrysene pollution: Potential new triggers for nonalcoholic fatty liver disease and hepatitis, insights from juvenile Siniperca chuatsi
Researchers exposed juvenile mandarin fish to nanoplastics and the pollutant chrysene, both individually and in combination, and examined the effects on liver health. They found that the combined exposure caused more severe liver damage than either contaminant alone, triggering fat accumulation and inflammatory responses in liver tissue. The study suggests that the interaction between nanoplastics and other environmental pollutants may amplify harmful effects on fish liver function.
Metal load and oxidative stress driven by organotin compounds on rainbow trout
Researchers injected rainbow trout with two forms of tributyltin — a toxic antifouling chemical once widely used in marine paints and now banned — and found that both compounds caused oxidative stress and altered antioxidant defenses in the liver within days. The findings confirm that tributyltin residues still present in aquatic environments pose ongoing ecotoxicological risks to freshwater fish.
Ingested plastic transfers hazardous chemicals to fish and induces hepatic stress
Researchers fed fish polyethylene plastic fragments collected from the ocean — which had absorbed surrounding pollutants — and found the fish bioaccumulated toxic chemicals and developed liver damage. The study demonstrates that ingested marine plastic acts as a delivery vehicle for harmful contaminants, compounding the health risks of plastic pollution in seafood.
Environmental Contaminants in Fish Products: Food Safety Issues and Remediation Strategies
This review provides an overview of environmental contaminants found in fish products, including heavy metals, persistent organic pollutants, and microplastics, and their risks to human health through seafood consumption. The combined presence of multiple contaminants in fish can create compounding toxic effects that are greater than any single pollutant alone. The authors recommend better monitoring and cleanup strategies, including bioremediation, to protect both marine ecosystems and the people who eat seafood.
The influence of ecological factors in the modulation of pollution biomarkers of two small pelagic marine fish
Researchers examined how ecological factors such as body condition, sex, and season modulate pollution biomarker responses in two small pelagic fish species, finding that biological variability must be accounted for when using hepatic biomarkers to assess marine contamination levels.
Bioaccumulation and Bioremediation of Heavy Metals in Fishes—A Review
This review summarizes how heavy metals accumulate in fish tissues through contaminated water and enter the human food chain, posing serious public health concerns. The paper discusses bioremediation techniques using microorganisms and other methods to remove heavy metals from aquatic environments, which is relevant because microplastics can carry and concentrate these same toxic metals.
Systematic Review of Microplastic Characterization Methods and Associated Toxicological Outcomes in Fish
This systematic review evaluated methods used to identify microplastics and their health effects in fish. The findings showed that microplastic exposure causes liver and gill damage, behavioral changes, and oxidative stress in fish, which matters for human health because contaminated fish is a common part of our diet.
