Concentration-dependent morphological effects of PCB126 exposure: (a) Mean pericardial sac area and body length of embryos exposed to increased concentration of PCB126. Values are mean ± SEM. Asterisks represent statistical significance at * p < 0.05, ** p < 0.01, and *** p < 0.001; n = 4 pools of five embryos (two biological replicates). (b) Representative images of embryos at 80 hpf exposed to increasing concentrations of PCB126 (Scale bar = 200 µm).
