The avoidance behavior of C. elegans induced by sodium arsenite. (a) Schematic diagram of C. elegans avoidance index. (b) Schematic representation of the avoidance response of C. elegans exposed to 0, 0.2, and 0.5 mM sodium arsenite concentrations at 8, 12, and 24 h. (c) 8-h avoidance index. (d) 12-h avoidance index. (e) 24-h avoidance index. (f) Turning index (one-way analysis of variance was used for comparisons among multiple groups, and then the Dunnett-t test was used for comparison). (^∗∗∗p < 0.001, ^∗∗∗∗p < 0.0001, and ns p > 0.05).
