In the present study, specific polychlorinated biphenyl (PCB) congeners were examined for embryo and early life stage mortality in zebrafish (Danio rerio). A set of eight PCBs and two hydroxylated PCBs and 17{beta}-estradiol were tested. Of the compounds tested, 4{prime}-OH-PCB30 (hydroxylated polychlorinated biphenyl) and PCB104 were found to be highly toxic to embryos following maternal exposure and transfer to the oocyte. It was also observed that 17{beta}-estradiol exposure resulted in a high incidence of embryo mortality. Analysis of estrogen receptor levels during embryonic development showed increased mRNA (ribonucleic acid) levels from the 1K stage to 50% epiboly. Following injection of the different compounds, the estrogen receptor mRNA levels were also analyzed in adult male fish to determine if there was a correlation between embryo mortality and estrogenicity of the studied PCBs. The two PCBs that were highly embryo toxic were observed to be estrogenic.
