ClearComparison 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.
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.
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.
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.
Microplastics aggravate the adverse effects of methylmercury than inorganic mercury on zebrafish (Danio rerio)
Researchers exposed zebrafish embryos to polystyrene microplastics combined with two forms of mercury and found that the microplastics significantly increased the accumulation of methylmercury in the fish. The combination of microplastics and methylmercury caused worse developmental abnormalities, delayed hatching, and greater oxidative stress than either pollutant alone. The study suggests that microplastics can act as carriers for toxic metals, amplifying their harmful effects on aquatic organisms.
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.
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.
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.
Combined toxicity of polystyrene microplastics and sulfamethoxazole on zebrafish embryos
Researchers investigated the combined toxicity of polystyrene microplastics and the antibiotic sulfamethoxazole on zebrafish embryos. They found that co-exposure caused significant mortality, malformations, reduced movement, increased heartbeat rates, and endocrine disruption including elevated vitellogenin and hormone levels. While the two pollutants showed antagonistic rather than synergistic interactions, their combined effects were still substantial, highlighting the importance of studying microplastic-pollutant mixtures in aquatic environments.
The Exploration of Joint Toxicity and Associated Mechanisms of Primary Microplastics and Methamphetamine in Zebrafish Larvae
Researchers studied how microplastics and methamphetamine together affect zebrafish larvae, since both pollutants frequently co-occur in waterways. The study found that polystyrene microplastics were more lethal than PVC types, and when combined with methamphetamine at higher concentrations, the toxic effects on survival, behavior, and intestinal health became significantly worse.
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.
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.
The combined toxic effects of polystyrene microplastics and different forms of arsenic on the zebrafish embryos (Danio rerio)
Researchers studied how polystyrene microplastics interact with different forms of arsenic and their combined effects on zebrafish embryos. The microplastics absorbed arsenic from the water and altered how the toxic metal accumulated in zebrafish tissues, changing its toxicity profile. The findings suggest that microplastics in the environment can modify how other pollutants affect living organisms, potentially making combined exposures more harmful than expected.
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.
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.
The Role of Synthetic Polymers in the Aquatic Environment and Its Implications in Danio Rerio as a Model Organism
Exposing zebrafish to polystyrene microplastics combined with silver nanoparticles caused significantly more oxidative damage, tissue injury in gills and intestines, and higher mortality than either contaminant alone. The study demonstrates that microplastics can act as carriers that enhance the toxicity of co-pollutants like silver nanoparticles, a combination effect that is highly relevant to understanding real-world aquatic contamination where multiple pollutants co-occur.
Toxic Effects of Polystyrene Microplastics and Sulfamethoxazole on Early Neurodevelopment in Embryo–Larval Zebrafish (Danio rerio)
Researchers exposed embryo-larval zebrafish to polystyrene microplastics and the antibiotic sulfamethoxazole to assess their individual and combined effects on early neurodevelopment. The study found that both contaminants individually caused neurodevelopmental toxicity, and their combination produced a significant synergistic effect, suggesting that co-exposure to microplastics and antibiotics may pose greater risks than either pollutant alone.
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.
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.
Combined effects of microplastics and chemical contaminants on the organ toxicity of zebrafish ( Danio rerio )
Researchers studied the combined effects of microplastics and chemical contaminants like PCBs and methylmercury on zebrafish organs over three weeks of exposure. They found that microplastics carrying adsorbed contaminants produced the most significant effects, particularly on the liver, compared to either microplastics or contaminants alone. The results indicate that microplastics may act as carriers that increase the delivery of harmful chemicals to organisms' tissues.
The combined toxic effects of polyvinyl chloride microplastics and di(2-ethylhexyl) phthalate on the juvenile zebrafish (Danio rerio)
Researchers studied the combined toxic effects of PVC microplastics and the plasticizer DEHP on zebrafish embryos and larvae. While PVC alone slowed hatching and increased death rates, the combination of PVC and DEHP actually showed some antagonistic effects, reducing certain types of damage compared to individual exposures. The study provides insight into how microplastics and their associated chemicals may interact in complex ways when organisms are exposed to them together in natural waters.
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.
Toxic effects of polystyrene microplastics on atrazine in zebrafish: Exogenous toxicity and endogenous mechanism
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.
