ClearBioaccumulation of polystyrene nanoplastics and their effect on the toxicity of Au ions in zebrafish embryos
Researchers studied the bioaccumulation of polystyrene nanoplastics in zebrafish embryos and their interaction with gold ions. They found that smaller nanoplastics readily penetrated the embryo's protective membrane and accumulated in lipid-rich regions, particularly the yolk. While nanoplastics alone caused only marginal toxic effects, their presence synergistically amplified the toxicity of gold ions through increased oxidative stress and inflammatory responses, suggesting that nanoplastics may worsen the harmful effects of co-occurring environmental contaminants.

Bioaccumulation of various nanoplastic particles in larval zebrafish (Danio rerio)
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.

Maternal transfer of nanoplastics to offspring in zebrafish (Danio rerio): A case study with nanopolystyrene
Researchers demonstrated maternal transfer of polystyrene nanoplastics in zebrafish by feeding exposed females and detecting particles in yolk sacs, livers, and guts of offspring, finding that transferred nanoplastics reduced antioxidant enzyme activity and caused bradycardia in embryos without major effects on overall reproductive success.
Polystyrene nanoplastics (20 nm) are able to bioaccumulate and cause oxidative DNA damages in the brain tissue of zebrafish embryo (Danio rerio)
Researchers microinjected 20-nanometer polystyrene nanoplastics into zebrafish embryos to simulate dietary or maternal exposure and tracked their fate over 120 hours. The study found that nanoplastics reached and bioaccumulated in the brain, causing oxidative DNA damage in the regions where they accumulated. The research team used transmission electron microscopy to image nanoplastics in a vertebrate brain for the first time, also observing increased mortality, developmental abnormalities, and elevated reactive oxygen species.
Toxicity of nanoplastics for zebrafish embryos, what we know and where to go next
This review integrates findings from studies on how polystyrene nanoplastics affect zebrafish embryo development, a widely used model for understanding toxicity. Researchers found that the functional coating on nanoplastic surfaces had a greater influence on toxic effects than particle size or concentration alone. The study highlights that surface chemistry is a critical and often overlooked factor in nanoplastic toxicity, and calls for more standardized study designs to improve comparability across research.
Polystyrene nanoplastics mediated the toxicity of silver nanoparticles in zebrafish embryos
Researchers studied how polystyrene nanoplastics interact with silver nanoparticles and affect zebrafish embryo development. They found that nanoplastics can act as carriers for silver nanoparticles in water, and the combination altered patterns of oxidative stress, immune response, and metabolic function compared to either pollutant alone. The study highlights how nanoplastics may change the way other environmental contaminants affect aquatic organisms.

Researchers exposed zebrafish embryos to polystyrene nanoplastics at various concentrations and found significant developmental abnormalities including reduced hatching rates and increased malformations. The nanoplastics activated oxidative stress responses and DNA repair pathways, indicating cellular damage during critical early development stages. The study provides mechanistic evidence for how nanoplastic exposure can disrupt normal embryonic development in aquatic organisms.
Neurotoxicity of polystyrene nanoplastics with different particle sizes at environment-related concentrations on early zebrafish embryos
Researchers exposed zebrafish embryos to polystyrene nanoplastics of different sizes at concentrations found in the environment and observed significant brain damage. The nanoplastics caused loss of neurons, shortened nerve fibers, and disrupted brain signaling systems that control behavior. Smaller nanoplastics caused the most severe damage because they could pass through protective barriers more easily, suggesting that the tiniest plastic particles pose the greatest risk to brain development.
Polystyrene microplastics and nanoplastics induce neurotoxicity in zebrafish via oxidative stress and neurotransmitter disruption
Researchers exposed zebrafish embryos to polystyrene micro- and nanoplastics and found that both particle sizes caused neurodevelopmental toxicity, with nanoplastics being more potent. The plastic particles induced oxidative stress in the brain and disrupted neurotransmitter levels critical for normal neural development. The study suggests that microplastic and nanoplastic contamination in aquatic environments may pose significant risks to the neurological development of fish.
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.

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.
Polystyrene nanoplastics accumulate in ZFL cell lysosomes and in zebrafish larvae after acute exposure, inducing a synergistic immune response in vitro without affecting larval survival in vivo
Polystyrene nanoplastics were shown to be internalized in zebrafish liver cells and accumulate in lysosomes, and while they triggered an immune response in cell cultures, they did not affect larval zebrafish survival in short-term exposures. This suggests that cellular toxicity may not always translate directly to whole-organism mortality at acute exposure levels.
