Morphological effects of exposure to the herbicides atrazine and diuron during their first 96 hpf in zebrafish larvae at 7 dpf. (A) Atrazine exposure effects on the body length (µm); (B) atrazine exposure effects on the head length (µm); (C) atrazine exposure effects on the mesencephalon width (µm); (D) atrazine exposure effects on the forebrain width (µm); (E) atrazine exposure effects on the ocular distance (µm); (F) representative images of the most prominent morphology or teratogenic effects observed in individuals exposed to atrazine during the 7 dpf; (G) diuron exposure effects on the body length (µm); (H) diuron exposure effects on the head length (µm); (I) diuron exposure effects on the mesencephalon width (µm); (J) diuron exposure effects on the forebrain width (µm); (K) diuron exposure effects on the ocular distance (µm); (L) representative images of the most prominent morphology or teratogenic effects observed in individuals exposed to diuron during 7 dpf. Data were analyzed by one-way ANOVA followed by a post-hoc Tukey’s test. ** represents significant differences at p ≤ 0.01, ***p ≤ 0.001, and ****p ≤ 0.0001 in relation to control.
