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.
Effects of pristine or contaminated polyethylene microplastics on zebrafish development
Researchers examined the effects of both pristine and pollutant-contaminated polyethylene microplastics on zebrafish development through chronic exposure. The study assessed how microplastics, both alone and as carriers of adsorbed organic pollutants, affect developing fish. The findings provide new insights into how contaminated microplastics may create additional routes for toxic compounds to enter aquatic food webs.
