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.
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.
Single and combined effects of microplastics and cadmium on juvenile grass carp (Ctenopharyngodon idellus)
Researchers found that combined exposure to polystyrene microplastics and cadmium in juvenile grass carp caused greater physiological stress than either pollutant alone, with microplastics enhancing cadmium accumulation and intensifying oxidative stress and immune responses.
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.
Effects of Exposure to Cadmium, Microplastics, and Their Mixture on Survival, Growth, Feeding, and Life History of Daphnia magna
Researchers examined how polyethylene microplastics altered cadmium toxicity to Daphnia magna, finding that microplastic co-exposure modified cadmium bioavailability and affected survival, growth, feeding rates, and reproductive outcomes in this ecologically important species.
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.
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.
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.
Comparison of the combined toxicity of polystyrene microplastics and different concentrations of cadmium in zebrafish
Researchers studied the combined toxic effects of polystyrene microplastics and cadmium at different concentrations in zebrafish over a 10-day exposure period. The study found that microplastics could either amplify or reduce cadmium toxicity depending on the metal concentration, affecting survival, growth, and antioxidant responses in complex ways.
Combined toxicity of microplastics and cadmium on the zebrafish embryos (Danio rerio)
Researchers exposed zebrafish embryos to polystyrene microplastics combined with cadmium to assess their combined toxic effects on aquatic organisms. The study found that co-exposure produced greater negative impacts on survival and heart rate than either pollutant alone, with toxicity increasing in a concentration-dependent manner.
Adverse Effects of Co-Exposure to Cd and Microplastic in Tigriopus japonicus
Researchers exposed the marine copepod Tigriopus japonicus to combined cadmium and polystyrene microplastic exposure using a full concentration-response design. Co-exposure increased toxicity compared to either contaminant alone, with effects on survival, reproduction, and development, indicating synergistic or additive interactions between cadmium and microplastics.
Impacts of Microplastics, Cadmium, and Their Mixtures on Biochemical Biomarkers in the Freshwater Bivalve Corbicula fluminea (Bivalvia, Corbiculidea)
This study evaluated the combined impacts of microplastics and cadmium on biochemical biomarkers in a freshwater organism, finding that co-exposure caused greater oxidative stress and cellular damage than either contaminant alone. Microplastics appear to enhance cadmium bioavailability and toxicity.
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.
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.
Acute co-exposure to microbeads and cadmium enhances accumulation and alters plasma biochemical markers and stress indicators in Korean rockfish, Sebastes schlegeli
Researchers found that combined acute exposure of Korean rockfish to microbeads and cadmium enhanced heavy metal accumulation in fish tissues more than cadmium alone, with microplastics facilitating metal adsorption and transport in ways that increase contaminant bioavailability.
Combined effects of polyvinyl chloride or polypropylene microplastics with cadmium on the intestine of zebrafish at environmentally relevant concentrations
Researchers exposed zebrafish to PVC or polypropylene microplastics combined with cadmium, a toxic heavy metal often used in plastic manufacturing. The microplastics increased cadmium buildup in the fish intestines and worsened gut damage, including inflammation and disruption of the intestinal barrier. This is relevant to human health because people can be exposed to similar combinations of microplastics and heavy metals through contaminated seafood.
Microplastics and copper effects on the neotropical teleost Prochilodus lineatus: Is there any interaction?
Researchers exposed the neotropical fish Prochilodus lineatus to polyethylene microplastics and copper separately and together, finding that microplastics alone caused oxidative stress and genotoxic effects, while combined exposure with copper did not consistently amplify harm compared to either stressor alone.
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.
Multi-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.
Integrated analysis of zebrafish gut microbiota and liver transcriptome responses to polystyrene microplastics and cadmium
Researchers exposed zebrafish to polystyrene microplastics and cadmium, both individually and combined, and found that combined exposure caused more severe disruption to gut bacteria and liver gene expression than either pollutant alone. The study revealed that microplastics decreased beneficial gut bacteria while increasing pathogenic species, and the combined treatment suppressed liver xenobiotic metabolism and antioxidant pathways.
Individual 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.
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.
Mechanisms of Gills Response to Cadmium Exposure in Greenfin Horse-Faced Filefish (Thamnaconus septentrionalis): Oxidative Stress, Immune Response, and Energy Metabolism
This study examined how cadmium, a toxic heavy metal from industrial pollution, damages the gills of a marine fish species by triggering oxidative stress, immune responses, and energy imbalances. While not directly about microplastics, the findings are relevant because microplastics can absorb and transport heavy metals like cadmium into aquatic food chains. Understanding how fish respond to cadmium exposure helps assess the combined risks when heavy metals hitchhike on microplastic particles.
