Adverse effects of dimethachlor on embryo development of zebrafish. (A) Average viability of zebrafish embryos decreased in a dose-dependent and time-dependent manner following dimethachlor exposure. (B) Daily number of hatched eggs between 48 hpf and 96 hpf at each concentration. (C) Representative bright-field images of overall phenotypic change, captured by LEICA DM 2500. Scale bar: 500 μm. (D) Total body length was quantified using “Length” in ImageJ software, p-values that indicate significant differences: *p < 0.05, **p < 0.01, and ***p < 0.001.
