ClearToxic effects of polystyrene microbeads and benzo[α]pyrene on bioaccumulation, antioxidant response, and cell damage in goldfish Carassius auratus
Researchers exposed goldfish to polystyrene microbeads and benzo[a]pyrene, both individually and in combination, to assess their toxic effects over 120 hours. They found that combined exposure significantly increased oxidative stress, liver damage, and cell death compared to single-compound exposure. The study suggests that microplastics can act as carriers for harmful chemicals, amplifying their toxic impact on aquatic organisms.
Individual and combined effects of microplastics and diphenyl phthalate as plastic additives on male goldfish: A biochemical and physiological investigation
Male goldfish exposed to both microplastics and the plasticizer chemical DPP (diphenyl phthalate) together showed significant liver damage, disrupted fat and sugar metabolism, and hormonal imbalances including decreased testosterone and increased estrogen. The combined exposure was more harmful than either pollutant alone, demonstrating how microplastics and their chemical additives can work together to disrupt the endocrine system.
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.

Toxicological effects of microplastics and phenanthrene to zebrafish (Danio rerio)
Researchers exposed zebrafish to polystyrene microplastics, the pollutant phenanthrene, and a combination of both to assess their toxicity over 24 days. They found that co-exposure amplified oxidative stress, suppressed immune gene expression, and significantly disrupted the gut microbiome compared to either contaminant alone. The study suggests that microplastics can worsen the toxic effects of organic pollutants in aquatic organisms by altering how chemicals accumulate and interact in the body.
Co-exposure to different sized polystyrene microplastics and benzo[a]pyrene affected inflammation in zebrafish andbronchial-associated cells
Researchers found that co-exposure to different sizes of polystyrene microplastics together with the carcinogen benzo[a]pyrene produced greater toxic effects in aquatic organisms than either pollutant alone. The study highlights the importance of studying microplastic interactions with other contaminants rather than treating them as isolated stressors.
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.
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.
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.
Effects of combined exposure to 17α-methyltestosterone and polystyrene microplastics on lipid metabolism and the nervous system in Danio rerio
Researchers exposed zebrafish to a combination of polystyrene microplastics and a synthetic androgen and found significant disruptions to lipid metabolism in the liver and neural function in the brain. The co-exposure caused fatty degeneration of liver cells and altered key signaling pathways involved in nerve communication. The study highlights the compounded risks that arise when aquatic organisms encounter multiple pollutants simultaneously.
Combined effects of co-exposure to microcystin-LR and polystyrene microplastics on growth, brain pathology and thyroid hormone homeostasis in adult zebrafish
Researchers exposed zebrafish to microcystin-LR (a toxin from algal blooms) combined with polystyrene microplastics and found that the combination caused significantly worse brain damage and thyroid hormone disruption than either pollutant alone. The microplastics appeared to overwhelm the fish's ability to compensate for the algal toxin, leading to hormone imbalances that could affect growth and development. This is concerning because algal blooms and microplastics frequently occur together in polluted waterways, and their combined effects on the hormone system may be worse than expected.
The synergetic effects of 4-nonylphenol and polyethylene microplastics in Cyprinus carpio juveniles using blood biomarkers
Researchers found that polyethylene microplastics and the endocrine disruptor 4-nonylphenol produce synergistic toxic effects in juvenile carp, with combined exposure causing greater disruption to blood biomarkers than either contaminant alone.

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 exposure of polystyrene microplastics and benzo[a]pyrene in rat: Study of the oxidative stress effects in the liver
Researchers exposed rats to polystyrene microplastics and the carcinogen benzo[a]pyrene, both individually and in combination, to study oxidative stress in liver tissue. The combined exposure caused significantly more liver damage, inflammation, and oxidative stress than either pollutant alone. The study suggests that microplastics may amplify the harmful effects of environmental carcinogens when both are ingested together.
Effects of combined exposure to polystyrene microplastics and 17α-Methyltestosterone on the reproductive system of zebrafish
Researchers exposed zebrafish to polystyrene microplastics combined with a synthetic hormone (17-alpha-methyltestosterone) and found that the combination caused more severe reproductive damage than either substance alone. The co-exposure reduced mature egg and sperm production, disrupted hormone-related gene expression, and lowered reproductive hormone levels. This suggests that microplastics can make the effects of hormone-disrupting chemicals in the environment worse, which is concerning for both wildlife and human reproductive health.
Polystyrene microplastics enhance the microcystin-LR-induced gonadal damage and reproductive endocrine disruption in zebrafish
Zebrafish exposed to polystyrene microplastics along with microcystin-LR (a common toxin from algae blooms) suffered worse reproductive damage than when exposed to either pollutant alone. The microplastics acted as carriers that increased the amount of toxin accumulating in the fish's reproductive organs. This study demonstrates that microplastics can worsen the effects of other water pollutants by helping toxic chemicals build up in the body.

Polystyrene microplastics modulate the toxic effects of bisphenol A in the early stages of zebrafish development
This study investigated whether polystyrene microplastics affect the toxicity of bisphenol A (BPA) during zebrafish embryo development by co-exposing fish to both contaminants. The PS microplastics modulated BPA toxicity in complex ways—in some developmental endpoints amplifying harm, in others providing partial protection—underscoring the unpredictability of combined plastic-chemical exposures.
Synergistic endocrine disruption and cellular toxicity of polyethylene microplastics and bisphenol A in MLTC-1 cells and zebrafish
When zebrafish and testicular cells were exposed to polyethylene microplastics and the chemical bisphenol A (BPA) together, the combination caused significantly worse reproductive harm than either pollutant alone, including reduced cell survival and disrupted hormone-producing gene activity. This matters because people are commonly exposed to both microplastics and BPA through food packaging, and their combined effect on reproductive health may be greater than expected.
Detrimental effects of individual versus combined exposure to tetrabromobisphenol A and polystyrene nanoplastics in fish cell lines
Researchers tested how combined exposure to the flame retardant tetrabromobisphenol A and polystyrene nanoparticles affects freshwater fish cells. They found that co-exposure to even low concentrations of both pollutants caused subtle changes in cell viability and generated oxidative DNA damage. The study suggests that the interaction between nanoplastics and chemical pollutants in aquatic environments may pose compounding risks to fish health.
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.
Joint effects of micro-sized polystyrene and chlorpyrifos on zebrafish based on multiple endpoints and gut microbial effects
