Exploratory behavior of zebrafish larvae at 7 dpf after atrazine or diuron exposure during the initial 96 hpf. Columns depict means ± S.E.M. Sample sizes are n = 27 for each group. (A) Atrazine exposure effects on total distance traveled (m); (B) atrazine exposure effects on mean speed (m/s); (C) atrazine exposure effects on time in movement (s); (D) atrazine exposure effects on time in the outer area (s) of the well; (E) diuron exposure effects on total distance traveled (m); (F) diuron exposure effects on mean speed (m/s); (G) diuron exposure effects on time in movement (s); (H) diuron exposure effects on time in the outside area (s). Data were analyzed by one-way ANOVA followed by a post-hoc Tukey’s test. Asterisks represent significant differences at *p ≤ 0.01 and ***p ≤ 0.001 in relation to controls.
