ClearCombined 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.
Combined effects of microplastics and copper on antioxidant capacity, gut microbiome, and metabolomics of Pseudorasbora parva
Researchers studied the combined effects of microplastics and copper on the freshwater fish Pseudorasbora parva, examining antioxidant capacity, gut microbiota, and metabolic responses. They found that the presence of microplastics alongside copper actually reduced copper accumulation in tissues and lessened oxidative damage compared to copper exposure alone. The study suggests that while microplastics can alter the toxicity profile of metals in fish, the interactions are complex and involve metabolic adjustments that balance cellular repair and energy expenditure.
Combined effects of microplastics and copper on oxidative responses in zebrafish (Danio rerio)

Long-term effects of individual and combined exposure to microplastics and copper in zebrafish hypothalamic-pituitary-gonadal axis – A multi-biomarker evaluation
This study exposed zebrafish to microplastics, copper, and both combined for 30 days and examined effects on their reproductive system. The combination of microplastics and copper caused greater hormonal disruption and oxidative stress than either pollutant alone, affecting genes that control reproduction in both male and female fish. These findings suggest that microplastics interacting with metal pollution in waterways could compound reproductive harm in aquatic organisms and potentially in humans who consume contaminated fish.

Researchers found that combined exposure to microplastics and copper in goldfish significantly enhanced copper accumulation and tissue damage in the hepatopancreas and intestine, triggering oxidative stress, inflammation, apoptosis, and autophagy beyond the effects of either pollutant alone.
Combined toxic effects of cadmium and environmental microplastics in Aphanius fasciatus (Pisces, Cyprinodontidae)
Researchers found that combined exposure to cadmium and microplastics in killifish caused oxidative stress and spinal deformities, though the two pollutants did not show clear synergistic interaction, likely because microplastics reduced cadmium bioavailability.
Single and combined acute and subchronic toxic effects of microplastics and copper in zebrafish (Danio rerio) early life stages
Researchers exposed zebrafish embryos and larvae to microplastics, copper, and their combinations to assess individual and combined toxic effects. They found that microplastics alone caused limited harm, but when combined with copper, the mixture produced altered biochemical responses and changes in gene expression. The study suggests that microplastics can modify the toxicity of heavy metals in aquatic organisms during early development.
Toxicity of microplastics and copper, alone or combined, in blackspot seabream (Pagellus bogaraveo) larvae
Researchers examined the toxicity of microplastics and copper, alone and combined, on blackspot seabream larvae, finding that microplastic-copper mixtures can alter biochemical biomarkers and gene expression related to oxidative stress and immune response in developing fish.
Combined effects of copper and microplastics on physiological parameters of Tubastrea aurea corals
Combined exposure of the azooxanthellate coral Tubastrea aurea to copper ions and polystyrene microplastics produced synergistic toxicity, reducing photosynthetic activity and elevating oxidative stress markers more than either pollutant alone, suggesting compounding risks in metal-contaminated coastal waters.
The impact of microplastics and copper on sex ratio and oxidative stress: analysis in zebrafish intestine, gonad and brain
Researchers exposed zebrafish embryos to copper, polyethylene, and polystyrene microplastics individually and in combination, finding that copper caused high mortality, PE alone induced a feminization trend, and co-exposure amplified adverse effects on sex differentiation and antioxidant enzyme activity.
Combined toxicity of polyvinyl chloride microplastics and copper to marine jacopever (Sebastes schlegelii)
Researchers studied the combined effects of PVC microplastics and copper on a marine fish species and found that the two pollutants together caused significantly more harm than either one alone. The microplastics accelerated copper buildup in the fish's liver, leading to greater oxidative damage and growth problems. This is relevant to human health because fish that accumulate both microplastics and heavy metals may pass those contaminants to people through the food chain.
Multi‐Biomarkers' Responses in Gills of Oreochromis niloticus Exposed to Glyphosate and Polyethylene Microplastic, Isolated and in Mixture
Researchers exposed tilapia fish to polyethylene microplastics and the herbicide glyphosate, both alone and in combination, and examined gill tissue for signs of damage. They found that the mixture of both contaminants caused more severe oxidative stress and tissue damage than either pollutant alone. The study suggests that microplastics and agricultural chemicals may interact in waterways to amplify harmful effects on fish health.
Single and Combined Effects of Microplastics and Cadmium on the Cadmium Accumulation and Biochemical and Immunity of Channa argus
Researchers investigated the single and combined effects of microplastics and cadmium on juvenile snakehead fish, finding that co-exposure caused greater tissue damage, oxidative stress, and immune disruption than either pollutant alone.
Single and combined effects of microplastics and cadmium on the cadmium accumulation, antioxidant defence and innate immunity of the discus fish (Symphysodon aequifasciatus)
Researchers studied how polystyrene microplastics interact with cadmium toxicity in discus fish and found that the presence of microplastics actually reduced cadmium accumulation in the fish's body. However, the microplastics independently caused oxidative stress and altered immune responses. The study reveals that the combined effects of microplastics and heavy metals on aquatic organisms are complex and do not simply add together.
Individual and Combined Toxic Effects of Nano-ZnO and Polyethylene Microplastics on Mosquito Fish (Gambusia holbrooki)
Researchers studied the individual and combined effects of polyethylene microplastics and zinc oxide nanoparticles on mosquito fish. The combination caused greater damage to liver tissue, blood parameters, and antioxidant systems than either pollutant alone. The findings suggest that microplastics interacting with other environmental contaminants can amplify toxic effects in aquatic organisms.
Combined toxicity of microplastics and copper on Goniopora columns
Researchers found that when microplastics and copper are present together in ocean water, they cause significantly more damage to coral than microplastics alone, reducing polyp length, killing symbiotic algae, and overwhelming the coral's antioxidant defenses. The combined exposure caused oxidative stress within just one day and progressively worsened over a week. This matters for human health because coral reef decline threatens the fisheries and coastal protection that millions of people depend on.
The impact of combined exposure to triphenyltin and microplastics on the oxidative stress, energy metabolism, and digestive function of common carp (Cyprinus carpio)
Exposing common carp to triphenyltin and microplastics individually and in combination found that combined exposure caused greater oxidative stress, disrupted energy metabolism more severely, and more strongly impaired digestive enzyme activity than either pollutant alone.
Polystyrene microplastics (PS-MPs) harness copper presence and promote impairments in early zebrafish (Danio rerio) larvae: Developmental, biochemical, transcriptomic approaches and nontargeted metabolomics approaches
This zebrafish study found that polystyrene microplastics combined with copper produced worse toxic effects than either pollutant alone, causing developmental problems, oxidative stress, immune disruption, and nerve damage in larvae. The combination also disrupted the fish's metabolism in ways that neither pollutant caused independently. This is concerning because microplastics readily absorb heavy metals like copper in the environment, meaning organisms are often exposed to both together.
Isolated and combined toxicity of PVC microplastics and copper on Pinctada fucata martensii: Immune, oxidative, and metabolomics insights
Researchers studied the individual and combined toxic effects of PVC microplastics and copper on pearl oysters over 13 days. They found that combined exposure caused more severe immune suppression, oxidative damage, and metabolic disruption than either pollutant alone. The study demonstrates that microplastics and heavy metals can interact to amplify their harmful effects on marine organisms.

Researchers investigated the combined effects of polystyrene microplastics and copper on the growth and nutritional profile of the freshwater green alga Raphidocelis subcapitata, examining whether co-exposure to these two contaminants produces interactive toxicity effects beyond individual exposures.
Microplastics and Copper Affect Zebrafish Behavior and Responses to Predation Threat
Zebrafish were exposed to two size classes of aged polyethylene microplastics with and without copper (10 µg/L) to assess effects on behaviour and predator response. Microplastics and copper together impaired anti-predator behaviour more than either pollutant alone, suggesting synergistic impacts on fish survival in contaminated environments.
Toxicological effects induced on early life stages of zebrafish (Danio rerio) after an acute exposure to microplastics alone or co-exposed with copper
Researchers exposed zebrafish embryos to microplastics alone and combined with copper to assess their joint toxicity during early development. They found that copper, both alone and combined with microplastics, reduced survival, increased oxidative stress, inhibited a key nervous system enzyme, and disrupted avoidance and social behaviors. The study suggests that microplastics may modulate copper toxicity in some biological endpoints, highlighting the importance of studying combined pollutant exposures during vulnerable developmental stages.
