Zebrafish, as a model organism, exhibit high sensitivity to environmental pollutants and has been widely used in microplastics (MPs) toxicology studies. However, the mechanisms underlying MPs’ effects on zebrafish have yet to be comprehensively summarized. This review systematically explores the sources, pollution status of freshwater MPs and their biological toxicity mechanisms using zebrafish as a model organism. This analysis reveals that the primary sources of MPs include sediment release, natural degradation of plastic products, and preci...
