ClearAdvances 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.
Research progress of model animal zebrafish in toxicity evaluation of microplastics
This review examines the use of zebrafish as a model organism for evaluating the toxicity of microplastics, synthesizing research on how microplastic exposure affects development, reproduction, and physiological function in this well-established vertebrate model. The authors highlight zebrafish as a particularly valuable system for mechanistic toxicology studies given its genetic tractability and the breadth of endpoints assessable across life stages.

From particle size to brain function: a zebrafish-based review of micro/nanoplastic-induced neurobehavioral toxicity and mechanistic pathways
This review uses zebrafish as a model to examine how micro- and nanoplastics cause neurobehavioral toxicity, linking particle size to brain function disruption. Researchers summarize evidence that these plastic particles impair fish behavior and cause molecular-level damage in the nervous system. The findings highlight the growing concern that micro- and nanoplastics are emerging neurotoxicants in aquatic environments.
Impacts of Environmental Concentrations of Nanoplastics on Zebrafish Neurobehavior and Reproductive Toxicity
Researchers exposed zebrafish to environmentally realistic levels of polystyrene nanoplastics and found they caused both brain and reproductive damage. The nanoplastics disrupted neurotransmitter signaling and impaired the hormonal pathway connecting the brain to reproductive organs, with different effects in males and females. These findings suggest that even low-level nanoplastic exposure could affect both brain function and fertility in aquatic life that humans may consume.

It discusses how findings in this widely used model organism may predict human health outcomes and calls for standardised exposure protocols.
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.
Research Progress of Zebrafish Model in Aquatic Ecotoxicology
This review examines how zebrafish are used as model organisms to study the toxic effects of environmental pollutants in water, including microplastics. Zebrafish are ideal because they reproduce quickly, are inexpensive to maintain, and allow researchers to study effects at the genetic, cellular, and whole-organism level. The paper provides a reference guide for scientists choosing model animals for aquatic toxicology research.
Nanoplastics Cause Neurobehavioral Impairments, Reproductive and Oxidative Damages, and Biomarker Responses in Zebrafish: Throwing up Alarms of Wide Spread Health Risk of Exposure
Researchers exposed adult zebrafish to polystyrene nanoplastics and found that the particles accumulated in the brain, liver, intestine, and gonads, causing significant behavioral and physiological changes. The fish showed disrupted energy metabolism, oxidative stress, and altered locomotion, aggression, and predator avoidance behaviors. The findings raise concerns about the widespread health risks of nanoplastic exposure, as these particles are small enough to cross biological membranes.
A review of the neurobehavioural, physiological, and reproductive toxicity of microplastics in fishes
This review summarizes how microplastics cause a range of harmful effects in fish, including behavioral changes, brain and immune system damage, oxidative stress, and reproductive disruption through interference with hormone signaling. These findings are relevant to human health because many of the same biological pathways affected in fish also exist in humans, and people consume fish that have accumulated microplastics.

Behavioural impact of microplastics on zebrafish development
Researchers assessed the developmental effects of environmentally relevant, household-derived microplastic fragments on zebrafish, rather than the pristine polymer spheres typically used in lab studies.

Evaluation of phenotypic and behavioral toxicity of micro- and nano-plastic polystyrene particles in larval zebrafish (Danio rerio)
Researchers exposed zebrafish embryos to polystyrene particles ranging from 50 nanometers to 10 micrometers and found that nearly all sizes caused physical abnormalities and changes in swimming behavior. Smaller particles were taken up more readily and distributed to organs including the brain and gut. These findings are relevant to human health because zebrafish share many biological pathways with humans, and the results suggest that both micro- and nano-sized plastics can cause developmental harm.
