Figure 2. Effects of embryonic As₂O₃ exposure in 6 dpf larvae and adult zebrafish. At 6 dpf, As₂O₃ exposure increased swim bladder inflation/volume (B), although its anterior–posterior length was shortened (A). (C) With change in swim bladder volume, As₂O₃ exposure also affected swimming behavior, with reduced down preference. (D) In adults, embryonic As₂O₃ exposure resulted in a reduced percentage of survivability in As₂O₃ exposed larvae (x), which was mainly detected at 13–23 dpf, compared to the control group (□). Data are presented as mean ± SEM, (∗ p ≤ 0.05) n = 30–90 per group), with significant differences relative to the control group ∗ (p ≤ 0.05).
