Mean deformity score (±SEM) of King’s Creek (black bars), Atlantic Wood F1 (white bars), and Atlantic Wood F2 (grey bars) embryos exposed to 300 µg/L benzo[k]fluoranthene (BkF), 1 µg/L 3,3’4,4’,5-pentachlorobiphenyl (PCB-126), or a mixture of 20 µg/L BkF and 100 µg/L fluoranthene (Fl). Values marked by * are significantly different from the DMSO-dosed population-matched control group at p<0.05 (ANOVA, Tukey-adjusted LSMeans). n = 30 individuals per treatment group.
