Activities of enzymatic antioxidants in larval zebrafish after 96 h exposure to 10− 6 M DQ, DQ-M, and DQ-D. (A) Enzyme activities of SOD in larval zebrafish after 96 h exposure to 10− 6 M DQ, DQ-M, and DQ-D. (B) Enzyme activities of CAT in larval zebrafish after 96 h exposure to 10− 6 M DQ, DQ-M, and DQ-D. Results were shown as the mean ± standard deviation (SD) of at least three independent experiments (N = 9 samples, *P < 0.05, **P < 0.01 and ***P < 0.001).
