Figure 2. Arsenic intake and excretion by mice exposed to deionized water with or without 3 mg/L sodium arsenite.

(A) Daily water intake; (B) Arsenic species in urine; (C) Arsenic species in feces. Four As species, including iAs (III), iAs (V), methyl-As (MMA) and dimethyl-As (DMA) were measured by HPLC-ICP-MS. CK means control mice. DB means diabetic mice. Values are mean values ± standard deviation (n = 7–8). Differences of results among groups were calculated using ANOVA followed by Tukey's post hoc test. * means significant difference (p < 0.05) compared to control mice.
