ClearMulti-Biomarker Responses of Asian Clam Corbicula fluminea (Bivalvia, Corbiculidea) to Cadmium and Microplastics Pollutants
Researchers exposed Asian clams to cadmium, microplastics, and their mixtures, then measured a battery of biomarkers including oxidative stress, energy metabolism, and neurotoxicity indicators. They found that the combined exposure to cadmium and microplastics produced interactive effects that differed from exposure to either contaminant alone. The study demonstrates that microplastics can modify the toxicity of heavy metals in freshwater bivalves, highlighting the importance of studying pollutant mixtures rather than individual contaminants.

Microplastics have additive effects on cadmium accumulation and toxicity in Rice flower carp (Procypris merus)
When a Chinese freshwater fish species was exposed to both microplastics and cadmium together, the microplastics increased cadmium buildup in the liver and gills and worsened tissue damage compared to either pollutant alone. The combined exposure caused greater oxidative stress and disrupted immune and metabolic pathways. This is important because microplastics and heavy metals often coexist in polluted waterways, and their combined effect on fish could affect the safety of freshwater fish that people eat.
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.
Biochemical impacts of PET microplastics and cadmium on Danio rerio under environmental conditions
This study examined the combined biochemical effects of PET microplastics and cadmium on zebrafish under environmentally relevant exposures, finding that co-exposure altered oxidative stress biomarkers, liver enzyme activity, and immune responses in ways that differed from single-contaminant exposures.
Additive effects of microplastics on accumulation and toxicity of cadmium in male zebrafish
Researchers exposed adult zebrafish to polyethylene microplastics and cadmium, both individually and in combination, for 21 days. They found that microplastics and cadmium together produced additive toxic effects, increasing cadmium accumulation in fish tissues, altering behavior, and causing more severe organ damage. The study suggests that microplastics in contaminated waterways may worsen the harmful effects of heavy metals on aquatic life.
Impacts of cadmium and microplastics on Neocaridina denticulata sinensis: Survival, growth, biochemistry, histopathology and gut microbiome
Researchers exposed freshwater shrimp to varying concentrations of microplastics and cadmium, both alone and in combination, to study their toxic effects and the organisms' recovery ability. They found that microplastics acted as cadmium carriers, promoting metal transport across gill barriers and causing oxidative stress, tissue damage, and gut microbiota imbalance. After seven days in clean water, most damage indicators and microbial diversity returned to near-normal levels, suggesting some recovery capacity.
Single and combined effects of microplastics and cadmium on juvenile grass carp (Ctenopharyngodon idellus)

Depuration and post-exposure recovery of oxidative stress responses to microplastics and cadmium in Pacific oyster (Crassostrea gigas)
Researchers exposed Pacific oysters to microplastic beads and cadmium, then transferred them to clean water to study recovery. They found that cadmium was eliminated much more slowly than the plastic beads, and oysters exposed to both contaminants together maintained higher levels of oxidative stress even during the recovery period. The study suggests that microplastics can enhance the toxic effects of heavy metals like cadmium through synergistic interactions that persist after the initial exposure ends.
Evaluation of single and combined effects of cadmium and micro-plastic particles on biochemical and immunological parameters of common carp (Cyprinus carpio)
Researchers investigated the individual and combined toxicity of cadmium and polystyrene microplastics on common carp over 30 days. They found that co-exposure to both pollutants produced more severe effects on liver enzymes, immune function, and biochemical markers than either pollutant alone. The study suggests that microplastics can enhance the toxicity of heavy metals in aquatic organisms, raising concerns about the combined impact of these co-occurring contaminants.
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.
