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.

The study positions zebrafish research as a key tool for advancing our understanding of how plastic particle exposure affects living organisms.
Advantages of the zebrafish (Danio rerio) model in solving contemporary problems of neurotoxicity, teratotoxicity and genotoxicity of xenobiotics
This paper is not about microplastics per se; it is a Polish-language review of the zebrafish (Danio rerio) model in toxicology, covering its use for assessing neurotoxicity, teratotoxicity, and genotoxicity of xenobiotics including nanoparticles and microplastics, with discussion of the micronucleus and comet assays used to detect genetic damage.
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.

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.

The study suggests that nanoscale polypropylene, one of the most commonly produced plastics, may pose risks to nervous system function in aquatic organisms.
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.

Nanoplastics impact the zebrafish (Danio rerio) transcriptome: Associated developmental and neurobehavioral consequences
Researchers exposed developing zebrafish larvae to polystyrene nanoplastics of two sizes and found dose-dependent accumulation in tissues along with swimming hyperactivity, despite no effects on mortality or hatching.
