Abstract
Waterborne bisphenol A (BPA) and diethyl phthalate (DEP) are endocrine disruptive chemicals that impact the reproductive system of fish. The present study checks the effectiveness of the reproductive capacity on zebrafish after BPA and DEP exposure, and consequently investigates its effect on their development and the swimming behavior of its offspring. The exposure of BPA and DEP to zebrafish reveals that the levels of ovarian 17β-estradiol (E2) and relative mRNA expression (RRE) ratios (Treatment/Control) of hepatic vitellogenin (vtg1) could be induced and decreased. Liver RRE levels in estrogen receptors (ERs) are also affected. Among the ERs, esr2a significantly increased upon BPA exposure, and esr1 and esr2b decreased upon DEP exposure. In addition, the ceratohyal cartilage (CH) angle of larvae whose mothers were exposed to BPA (F-BPA) was significantly bigger, but the CH angle of larvae whose mothers were exposed to DEP (F-DEP) was significantly smaller than the control. The swimming performance of larvae from F-DEP was more compromised than the control, but the situation did not appear in the larvae from the F-BPA group. The success rate of larvae hatching from F-BPA and F-DEP was lower than control group. Moreover, the successful rate of female spawns was higher in the control group compared to the treatment groups exposed to BPA and DEP. We suggested that both maternal BPA and DEP disrupt E2 levels, and influence the CH development of larvae, resulting in a decrease in successful hatching. Only the swimming behavior of larvae from maternal DEP was disrupted.
