The concentration of sodium arsenite in C. elegans increases with higher exposure concentrations. (a) Arsenic content in C. elegans after treatment with different concentrations of sodium arsenite. (b) Fluorescence intensity versus arsenic content standard curve. (c) Analysis of the difference in arsenic content in C. elegans after treatment with different concentrations of sodium arsenite (one-way analysis of variance was used for comparisons among multiple groups, and then the Dunnett-t test was used for comparison). (^∗∗∗∗p < 0.0001).
