Fig. 2. Liver metal levels after Mn exposure in drinking water. Levels of iron, manganese, copper and zinc in the liver were measured by inductively coupled plasma mass spectrometry (ICP-MS). Empty and closed bars represent water-drinking and Mn-drinking mice, respectively. Data were presented as means ± SEM (n = 6 per group) and were analyzed using two-way ANOVA followed by post-hoc comparisons.
