A positive relationship between Hg concentrations in different tissues of broiler chicken and corresponding feeds was obtained, indicating that Hg in feeds seemed to be responsible for the accumulation of Hg in chicken tissues. The differences in Hg concentrations among broiler chickens collected from five farms (p < 0:05) are apparent according to the Hg contents in feeds. The range of Hg in feed samples explains the differences in accumulation of Hg in different tissues of chicken samples collected from different farms. The bioaccumulation of Hg in different muscle tissue of broiler chicken through their feed showed significant differences (p > 0.01) (Fig. 1a and b).
