Researchers exposed larval zebrafish (Danio rerio) to 40-60 nm and 100 nm polystyrene nanoplastic particles using standard fish embryo toxicity and general behavioral toxicity assays from 6-120 hours post-fertilization, combining toxicity endpoints with fluorescence microscopy to confirm particle uptake and excretion. The study demonstrated nanoplastic accumulation within zebrafish larvae at tested concentrations, providing mechanistic insights into aquatic organism exposure dynamics for nanoplastics.

Size matters: Zebrafish (Danio rerio) as a model to study toxicity of nanoplastics from cells to the whole organism
Researchers used zebrafish as a model organism to study the toxic effects of polystyrene nanoplastics at both cellular and whole-organism levels. They found that smaller nanoplastic particles were taken up more readily by cells and caused greater oxidative stress and developmental abnormalities than larger particles. The study confirms that particle size is a critical determinant of nanoplastic toxicity, with the smallest particles posing the greatest biological risks.

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.

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.

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.
Eco-toxicity assessment of polypropylene microplastics in juvenile zebrafish (Danio rerio)
This study exposed young zebrafish to polypropylene microplastics for 28 days and found that the particles built up in their digestive tracts, causing oxidative stress, liver damage, and blood cell death. The damage increased with higher microplastic concentrations, and brain function was also affected through changes in a key neurotransmitter enzyme. These findings suggest that even common plastics like polypropylene can cause significant organ damage when ingested over time.

Uptake, tissue distribution, and toxicity of polystyrene nanoparticles in developing zebrafish (Danio rerio)
Researchers tracked the uptake and distribution of polystyrene nanoparticles in developing zebrafish and found that the particles accumulated in the yolk sac and then spread to the brain, liver, heart, and other organs. While the nanoparticles did not cause significant mortality or deformities, they did reduce heart rate and alter swimming behavior. The study suggests that nanoplastics can penetrate biological barriers and accumulate in multiple tissues during early development.

Researchers exposed zebrafish embryos to nanoplastics made from PET, the plastic commonly used in water bottles and food packaging. The nanoplastics accumulated in the liver, intestine, and kidneys, causing oxidative stress, damaging cell energy systems, and disrupting metabolism. This is the first comprehensive study of PET nanoplastic toxicity mechanisms, and it is particularly relevant because PET is one of the most common plastics that humans encounter daily.
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.
