Percent of KC DMSO EROD activity for King’s Creek, Atlantic Wood F1, and Atlantic Wood F2 embryos exposed to A) DMSO, B) 100 µg/L benzo[a]pyrene (BaP), C) 300 µg/L benzo[k]fluoranthene (BkF), D) 1 µg/L 3,3’4,4’,5-pentachlorobiphenyl (PCB-126), or E) a mixture of 20 µg/L BkF and 100 µg/L fluoranthene (Fl). Box plots represent median with upper and lower quartiles. Whiskers show the 5th and 95th percentiles. Mean is represented by + and outliers are represented by dots. Within a given panel, groups not marked by the same letter are statistically different at p < 0.05 (ANOVA, Tukey-adjusted LSMeans). n = 30 individuals per treatment group.
