Fig. 10. (A) Relative contribution of dietary and waterborne Cu uptake to the total body Cu burden accumulated over 7 weeks of exposure to experimental regime. Open bars, contribution of the waterborne Cu uptake; hatched bars, contribution of the dietary Cu uptake; LL, low waterborne Cu and low dietary Cu; LN, low waterborne Cu and normal dietary Cu; NL, normal waterborne Cu and low dietary Cu; NN, normal waterborne Cu and normal dietary Cu; NH, normal waterborne Cu and high dietary Cu level. (B,C) True bioavailability of dietary Cu (% of Cu ingested in food and retained during the exposure period). (B) Bioavailability of dietary Cu in normal water. (C) Bioavailability of dietary Cu in low waterborne Cu. See text for details of the calculation
