ClearExploring developmental toxicity of microplastics and nanoplastics (MNPS): Insights from investigations using zebrafish embryos
This review summarizes research on how micro- and nanoplastics harm embryo development using zebrafish as a model organism that shares genetic similarities with humans. Studies show these tiny plastic particles cause damage to the brain, heart, gut, and immune system of developing embryos, largely through oxidative stress and cell death pathways.
The Zebrafish as an Alternative Animal Model for Ecotoxicological Research and Testing
This review highlights zebrafish as a valuable model for studying the toxic effects of environmental contaminants, including microplastics, because they share many biological pathways with humans. Zebrafish embryos, larvae, and adults can be used to screen for harmful effects of pollutants quickly and at multiple life stages. The approach helps researchers understand how microplastics and other environmental contaminants might affect human health without requiring direct human testing.

Advances of microplastics ingestion on the morphological and behavioral conditions of model zebrafish: A review
This review summarizes research on how microplastic ingestion affects zebrafish, a popular lab animal that shares genetic similarities with humans. Studies show that microplastics cause a range of harmful effects in zebrafish, including abnormal behavior, oxidative stress, immune disruption, and reproductive problems, with smaller particles and higher concentrations causing the most damage. Since zebrafish are used as a model for human health, these findings raise concerns about what similar exposure levels could mean for people.

The study positions zebrafish research as a key tool for advancing our understanding of how plastic particle exposure affects living organisms.
Zebrafish Insights into Nanomaterial Toxicity: A Focused Exploration on Metallic, Metal Oxide, Semiconductor, and Mixed-Metal Nanoparticles
This review summarizes research on how various nanomaterials, including nano-sized plastics, affect zebrafish, which are commonly used as stand-ins for studying human health effects. Exposure to nanomaterials caused developmental defects, organ damage, behavioral changes, and reproductive problems in zebrafish. These findings help scientists understand the potential health risks of nanomaterial exposure to humans and the environment.
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.
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.
Neurotoxicity of Some Environmental Pollutants to Zebrafish
This review examines how environmental pollutants including microplastics, pesticides, and drug residues can damage the nervous system, using zebrafish as a model organism. The studies show that microplastics can cause neurotoxic effects on their own and also increase the brain-damaging potential of other pollutants they carry, which has implications for understanding how these contaminants might affect the human nervous system.

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.
Use of zebrafish (Danio rerio) as a model for research in toxicological studies
This review explains why zebrafish (Danio rerio) are a valuable model organism for toxicology research, summarizing how their biology, genetics, and organ systems resemble those of humans enough to yield insights about human health risks. Zebrafish are widely used in microplastic toxicology studies, and this review provides context for understanding the significance of zebrafish findings for human health. The paper covers applications across disease modeling and environmental toxicology.
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.
Current Aspects on the Plastic Nano- and Microparticles Toxicity in Zebrafish—Focus on the Correlation between Oxidative Stress Responses and Neurodevelopment
This review examines how nano- and micro-sized plastic particles cause toxic effects in zebrafish, focusing on the link between oxidative stress and neurodevelopmental damage. Researchers found that plastic particle exposure disrupts the balance of reactive oxygen species in cells, which can impair brain development and nervous system function. The study suggests these oxidative stress responses may serve as early warning signals of plastic particle toxicity in aquatic organisms.
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.
