Abstract
In a previous study, we demonstrated the next-generation effects and further transgenerational adverse effects of bisphenol A (BPA) in zebrafish. The adverse effects on reproductive factors, such as gonadal activity, fertility, hatching rate and malformation of embryo caused by the dietary administration on initial generation (F0) male and female zebrafish were continued until third filial (F3) generation. In this study, we examined how much amount of BPA contained in the diet was taken up by the zebrafish. We showed that only about 3.5-6.8% of BPA in the diet was taken into fish body. Also, we confirmed the transgenerational effects caused by 100 times lower amount of BPA than previous study. Even a low amount of BPA (1 μg/g diet) administered to F0 not only caused retraction of the ovaries and testes but also lowered the survival rate and increased the rate of malformation in the offspring. The effects were continued to F3 generation as previously described. Moreover, the sperm motility of the offspring of the BPA-treated ancestral animals was significantly lower, and this adverse effect was continued to F2 generations. These findings demonstrated that BPA at levels comparable to those ingested by humans can cause transgenerational adverse effects on fish reproduction.
