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.
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.
