ClearIndividual and combined effects of microplastics and cadmium on intestinal histology and microflora of Procypris merus
Researchers studied the individual and combined effects of microplastics and cadmium on the intestines of rice flower carp, a commercially important fish in southern China. They found that both pollutants alone caused intestinal damage and disrupted gut bacteria, but the combination produced even more severe effects. The study highlights how microplastics and heavy metals can interact to amplify harm to fish digestive health in polluted waterways.
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.

Influence of microplastics on the accumulation and chronic toxic effects of cadmium in zebrafish (Danio rerio)
Researchers exposed zebrafish to polystyrene microplastics combined with cadmium for three weeks and found that the presence of microplastics significantly increased cadmium accumulation in the liver, gut, and gills. The combined exposure caused greater oxidative damage, tissue inflammation, and disruption of protective gene activity than either pollutant alone. The study demonstrates that microplastics can enhance the toxicity of heavy metals in fish by acting as carriers that increase the body's uptake of harmful substances.
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.

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.
Physiological response and oxidative stress of grass carp (Ctenopharyngodon idellus) under single and combined toxicity of polystyrene microplastics and cadmium
Researchers examined the individual and combined toxicity of polystyrene microplastics and cadmium on grass carp. The study found that fish mortality increased with higher concentrations and that the presence of microplastics elevated cadmium concentration effects, with combined exposure inducing greater oxidative stress than either contaminant alone.
Effects of chronic co-exposure polystyrene nanoplastics and cadmium on liver function in Prussian carp (Carassius gibelio)
Researchers exposed Prussian carp to polystyrene nanoplastics and cadmium, both individually and together, for 21 days and found that the combination caused significantly worse liver damage than either pollutant alone. The nanoplastics enhanced cadmium accumulation in the liver and amplified oxidative stress, tissue damage, and immune gene activation. The findings demonstrate that nanoplastics and heavy metals can have synergistic toxic effects on aquatic organisms.
Combined effects of polystyrene microplastics and cadmium on oxidative stress, apoptosis, and GH/IGF axis in zebrafish early life stages
Researchers exposed zebrafish embryos to polystyrene microplastics and cadmium, both alone and together, and found that the combination caused significantly worse effects than either pollutant individually. Co-exposure amplified oxidative stress, increased cell death in the spine and esophagus, and disrupted growth hormone pathways more severely than single exposures. The findings suggest that microplastics and heavy metals in waterways may interact to create heightened risks for developing fish.
