Deformity observed in embryos of zebrafish exposed to sumithion. a. normal embryo after 12 h of exposure to 0 mg L⁻¹ of sumithion; b. lack of somite formation after 30 min of exposure to 0.2 mg L⁻¹ of sumithion; c. immature yolk sac after 2 h and 30 min of exposure to 0.2 mg L⁻¹ of sumithion; d. yolk sac damaged after 2 h and 15 min of exposure to 1.6 mg L⁻¹ of sumithion; e. yolk sac bud/snowball after 2 h and 30 min of exposure to 0.8 mg L⁻¹ of sumithion; f. shield after 4 h of exposure to 0.2 mg L⁻¹ of sumithion; g. unhatched segmentation after 5 h of exposure to 0.2 mg L-1 of sumithion; h. dark yolk sac after 5 h and 15 min of exposure to 1.6 mg L⁻¹ of sumithion; i. swelling/pustule after 5 h and 30 min of exposure to 0.4 mg L⁻¹ of sumithion; j. yolk sac elongated shape after 11 h of exposure to 1.6 mg L⁻¹ of sumithion; k. egg shell broken and yolk sac damaged after 11 h of exposure to 1.6 mg L⁻¹ of sumithion; l. dead egg after 24 h of exposure to 1.6 mg L⁻¹ of sumithion.
