ClearCo-exposure toxicity of microplastic and sumithion in Nile tilapia – changes in growth, hematology, histopathology of internal tissues and immune-antioxidant genes expression
Researchers studied the combined effects of polyamide microplastics and the pesticide sumithion on Nile tilapia, a widely farmed fish species. They found that co-exposure reduced growth, disrupted blood parameters, caused tissue damage in gills and intestines, and altered immune and antioxidant gene expression more severely than either pollutant alone. The study highlights that microplastics and pesticides together may pose amplified threats to fish health in contaminated aquaculture environments.
Combined effects of polystyrene microplastics and copper on antioxidant capacity, immune response and intestinal microbiota of Nile tilapia (Oreochromis niloticus)
Researchers examined the combined effects of polystyrene microplastics and copper on Nile tilapia and found that co-exposure increased copper accumulation in the liver and caused tissue damage in multiple organs. High concentrations of both contaminants together triggered oxidative stress, inflammation, and shifts in intestinal microbial communities. The study suggests that microplastics can worsen the toxic effects of heavy metals on freshwater fish.

Behavioral, biochemical, immune, and histological responses of Nile tilapia (Oreochromis niloticus Linnaeus, 1758) to lead, mercury, and pendimethalin exposure: individual and combined effects
This study tested the effects of lead, mercury, and a pesticide on Nile tilapia fish and found that exposure to all three together caused the worst damage, including organ injury, weakened immune systems, and high mortality. While not directly about microplastics, the research is relevant because microplastics can carry heavy metals like lead and mercury in water, potentially amplifying their toxic effects on fish. Since tilapia is a common food fish, these combined pollutant effects could impact seafood safety.

Combined impacts of microplastics and cadmium on the liver function, immune response, and intestinal microbiota of crucian carp (Carassius carassius)
Researchers exposed crucian carp to microplastics and cadmium, both alone and together, and found the combination caused more severe liver damage and immune disruption than either pollutant alone. Co-exposure also significantly altered the fish's gut bacteria after 21 days. This is concerning because microplastics and heavy metals frequently co-occur in polluted waterways, potentially amplifying harm to aquatic life.
Co-exposure to microplastics and bisphenol A increases viral susceptibility in largemouth bass (Micropterus salmoides) via oxidative stress
Researchers found that juvenile fish exposed to both microplastics and BPA (a chemical found in plastics) together became more susceptible to viral infection, even though neither pollutant alone had that effect. The combination shut down the fish's antioxidant defenses and caused liver cell death, weakening their immune system. This study is important because it shows that common pollutants can interact in unexpected ways, and real-world exposure to multiple contaminants may be more dangerous than lab tests of single substances suggest.
Biochemical effects of polypropylene microplastics on red tilapia (Oreochromis niloticus) after individual and combined exposure with boron
Researchers exposed red tilapia to polypropylene microplastics alone and combined with boron, finding that the mixture disrupted key brain and liver enzymes more severely than either pollutant alone. The study shows that microplastics can amplify the toxic effects of other environmental contaminants in fish.

Toxicity evaluation of the combination of emerging pollutants with polyethylene microplastics in zebrafish: Perspective study of genotoxicity, mutagenicity, and redox unbalance
Researchers exposed adult zebrafish to polyethylene microplastics combined with a mixture of common water pollutants for 15 days and assessed DNA damage, mutation rates, and oxidative stress. They found that microplastics alone caused DNA damage and nuclear abnormalities as severe as those caused by the pollutant mixture, challenging the assumption that microplastics are less harmful than chemical contaminants. The study revealed that the fish's antioxidant defenses were overwhelmed across multiple organs, suggesting widespread oxidative damage from microplastic exposure.

Short- and long-term single and combined effects of microplastics and chromium on the freshwater water flea Daphnia magna
Researchers investigated the individual and combined effects of microplastics and chromium on the water flea Daphnia magna in both short- and long-term experiments. They found that microplastics interacted with chromium, reducing its concentration in water, and that co-exposure caused acute toxicity but lacked the chronic effects seen with chromium alone. The study suggests that microplastics may alter the bioavailability and toxicity of metal pollutants in freshwater environments.
Polystyrene microplastics modulation of hexavalent chromium toxicity in quails: transcriptomic and toxicological insights
Researchers exposed quails to both polystyrene microplastics and hexavalent chromium — a cancer-causing heavy metal — for 12 weeks, finding that microplastics worsened the kidney damage caused by chromium by disrupting fat metabolism and energy production. The combination triggered severe kidney scarring (fibrosis) that neither pollutant caused as strongly on its own, illustrating how microplastics can amplify the toxicity of other environmental contaminants.
Polystyrene nanoplastic and engine oil synergistically intensify toxicity in Nile tilapia, Oreochromis niloticus
This study found that polystyrene nanoplastics and engine oil together caused much worse damage to Nile tilapia fish than either pollutant alone, triggering severe inflammation, blood cell changes, and oxidative stress. The combined exposure overwhelmed the fish's natural defenses and caused significant organ damage. Since tilapia is a widely consumed fish, this research highlights how mixtures of pollutants in waterways could compound health risks for both aquatic life and humans who eat contaminated seafood.
