Figure 2.

Alterations in morphology after developmental exposure to As, Pb, or a mixture of both from 1 to 120 hpf. A decrease in brain length in the 10 ppb mix treatment group was observed (A). No differences in total length were measured (B), but a decreased ratio of brain length to total length in the 10 ppb mix treatment group was also seen (C). n = 7 with 10 subsamples per treatment per replicate to total 70 fish per treatment group. Error bars represent standard deviation. * p < 0.05. Different letters indicate different statistical groupings in (A).
