Fig. 5. Liver Cu concentration (µmol g^–1 wet mass) during the exposure period (A) and the proportional contribution of liver Cu to total body Cu (B). Percentage data were transformed to arc sin for statistical analysis. Values are means ± S.E.M.; N=15 for weeks 0, 2 and 4, and N=9 for week 7 for each data point per treatment. Diamonds, low waterborne Cu and low dietary Cu; triangles, low waterborne Cu and normal dietary Cu; open circles, normal waterborne Cu and low dietary Cu; filled circles, normal waterborne Cu and normal dietary Cu; squares, normal waterborne Cu and high dietary Cu level. *Significantly higher level, significantly lower level relative to group on normal levels of water Cu and dietary Cu (ANOVA, P<0.05).
