Figure 6. F1 Larval Photomotor Response. Plots represent one of the evaluated F1 zebrafish cohorts and are representative of both evaluated cohorts (120 hours post fertilization). Exposure groups are indicated on the top of each panel and by color (left to right, grey: 0 ng/g, yellow: 1 ng/g, orange: 10 ng/g, and red: 100 ng/g PFHxA added to the F0 diet). In each panel, the first 3 min were the final light period (lower total movement), while the last 3 min were the final dark period. The 10 ng/g group exhibited significant hyperactivity in the dark period relative to controls (n = 48).
