Abstract：
:The pesticide flutolanil has been detected in fish and aquatic environments, but its potential impact on the endocrine function is unknown. In this study, two-month zebrafish were exposed to the environmentally relevant concentrations of flutolanil for 60 days to examine the reproductive endpoints on the gonad endocrine system. Increased 17 beta-estradiol (17β-E2) content and 17β-E2/T ratio and decreased testosterone (T) in male suggested that flutolanil produces the estrogenic effect. In support of this view, vitellogene (vtg1, vtg2) and cytochrome P450 aromatase 19a (cyp19a) expression were up-regulated in the male liver. The levels of global DNA methylation were increased in ovary. Parental zebrafish exposure to different concentrations of flutolanil affected the offspring development as shown by short body length, and increased mortality. Thus, these results demonstrate that flutolanil exposure results in gonad endocrine disruption, decreased reproduction, and developmental toxicity in F1, highlighting the importance of assessing the potential environmental risks of flutolanil application.
