Brief guidelines for zebrafish embryotoxicity tests.

There has been growing emphasis on environmental pollutants, including heavy metals, pesticides, and nanoplastics, owing to the escalating significance of environmental pollution as a major global issue. Various toxicities induced by these compounds have been consistently reported, and many cell lines and animal models have been used in toxicity studies. Zebrafish are one of the most widely used animal models for verifying the toxic effects of environmental pollutants, owing to their many advantages. In this study, we provide brief guidelines for zebrafish maintenance and mating methods, toxicant treatments, survival measurements, and morphological abnormalities.
