Zebrafish were treated with 0, 3, or 30 ppb atrazine from 1–72 hpf and gDNA was isolated at 72 hpf. Results indicated a significant reduction in the relative global methylation in both the 3 and 30 ppb atrazine treatments compared with the 0 ppb control (#p<0.05). Data is expressed as mean ± standard deviation (n≥5; *indicates a significant difference (p<0.05) between the 3 and 30 ppb samples)
