Concentrations of (−)-PCB149 and (+)-PCB149 and EF values following exposure to racemate.
(A) adult zebrafish exposed to 0.5 ng/L; (B) adult zebrafish exposed to 0.1 μg/L; (C) adult zebrafish exposed to 0.25 μg/L. Asterisks denote significant differences between treatments and control (determined by Dunnett post hoc comparison, P < 0.01, **). Error bars indicate standard deviations.
