Figure 1.

Embryonic morphology at 48 or 72 hpf treated with (A–D) 1.2% DMSO; (B–E) 5 nM BaP; (C–F) 50 nM BaP. BaP administration did not cause significant alterations in the body plan of zebrafish embryos. (G) Survival rates of 1.2% DMSO controls and 5 and 50 nM BaP treated embryos at different developmental stages. Results are reported as % derived from three independent experiments with at least 100 zygotes each.
