Toxicity of co-exposure of microplastics and lead in African catfish (Clarias gariepinus)
Researchers exposed African catfish to lead, microplastics, and a combination of both for 15 days and found that the combined exposure was more harmful than either pollutant alone. The mixture caused the greatest damage to blood cells, triggered stronger inflammatory responses, and disrupted the fish's antioxidant defenses. Since microplastics can carry heavy metals like lead on their surfaces, this study shows how microplastics may amplify the toxic effects of other pollutants in freshwater fish that people eat.

This study exposed zebrafish to a common water toxin (microcystin-LR) both alone and combined with polystyrene microplastics, and found that the microplastics made the liver damage significantly worse. The microplastics acted as carriers, increasing how much toxin accumulated in the fish liver and amplifying oxidative stress. This is relevant to human health because it shows microplastics can boost the harmful effects of other pollutants commonly found in drinking water sources.

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.
Polystyrene microplastics enhance microcystin-LR-induced cardiovascular toxicity and oxidative stress in zebrafish embryos
Zebrafish embryos exposed to both microplastics and microcystin-LR (a toxin produced by algal blooms) developed significantly worse heart and blood vessel damage than those exposed to the toxin alone. The microplastics amplified oxidative stress and cell death, suggesting that in polluted waterways where both contaminants coexist, the combined health risks may be greater than either one individually.

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.
Toxic effects of co-exposure to polystyrene nanoplastics and arsenic in zebrafish (Danio rerio): Oxidative stress, physiological and biochemical responses
In a zebrafish study, polystyrene nanoplastics made arsenic more toxic by helping the poison build up in the liver, gills, and intestines. The nanoplastics increased cell damage and oxidative stress beyond what arsenic alone would cause. This shows that nanoplastics can act as carriers for other toxic substances in water, potentially making environmental pollutants more dangerous to aquatic life and the food chain.

Researchers found that combining polystyrene microplastics with the common herbicide atrazine was more toxic to zebrafish than either pollutant alone, causing greater liver and gut damage. The combination also degraded water quality by reducing oxygen levels and increasing harmful nitrogen compounds. This is important because microplastics and pesticides frequently co-exist in the environment, meaning their combined effects on aquatic life and food safety may be worse than studies of individual pollutants suggest.
