Tissue distribution of 141Ce post-gavage. a Immediately post-gavage, nearly 100 % of both CeO2 were recovered in the stomach and to much lesser extent in other organs. b At 7 days post-gavage, the total tissue 141Ce detected in all organs examined was negligible (0.003 ± 0.001 %). c By 7 days post-gavage, less than 0.0004 % of dose was excreted in the urine. d Elimination of 141Ce via the feces was nearly 100 % from uncoated and 94 % from silica-coated CeO2. Data are mean ± SEM, n = 5/group
