However, zinc absorption and accumulation are as mainly concentrated in a specific region (areas indicated by arrow), similar distribution information of zinc was obtained for each sample by m-XRF maps in intestinal wall. Colorscale magnitude represents the level of relative zinc concentration. Different colors of colorscale represent amount and distribution of zinc in the intestinal wall. The sample of ZnSO4 group shows a less distribution for zinc and a lower amount of zinc in a specific region (Fig. 3). In contrast to ZnSO4 group sample, organic zinc (ZnMet,
ZnLys) groups have a greater amount of zinc in the intestinal wall specific region (Figs. 1 and 2). The greatest amount accumulation of zinc was detected in ZnMet group duodenal wall specific region (Fig. 1).
