Sterlet embryo viability following exposure to model genotoxicants: (A) embryos were exposed to BaP and etoposide from 2 hpf until 8 dpf; (B) embryos were exposed to camptothecin (CPT) from 2–24, 24–48, and 48–72 hpf; (C) embryos were injected with etoposide at the 1-cell stage. Embryo mortality was monitored daily for 8 days. Results represent the mean of six independent experiments. Error bars represent standard error of the mean. Asterisks indicate significant differences compared to control at the same time point (* p < 0.05, Kruskal–Wallis test).
