Abstract

Bixafen (BIX), a widely used succinate dehydrogenase inhibitor (SDHI) in agricultural disease control, has garnered significant attention due to its known hazardous effects on aquatic organisms. In this study, we exposed zebrafish embryos to 0.1, 0.2, and 0.3 μM BIX, to explore the impact of BIX on liver and pancreas. The results showed that BIX caused deformities and dysfunction in zebrafish embryos, including spinal curvature, pericardial edema, heart rate decrease, and hatching delay. Moreover, BIX significantly affected the development of the liver and pancreas in zebrafish and downregulated zebrafish fabp10a gene expression. Overall, this study presents strong evidence for BIX’s potential toxicity to zebrafish liver and pancreas. The results may provide new insights into the evaluation of BIX’S impact on aquatic organisms.
