Oral exposure to As causes hearing loss in young mice aged 3 months. ABR thresholds (means ± SD) at 4, 12, 20 and 32 kHz in the control group (ctrl, closed squares, n = 9) and exposure group (As, open trianglers, n = 8) before (A) and after exposure to As (B) are presented. Significant differences (*p < 0.05; **p < 0.01) were determined by the Mann-Whitney U test.
