The broiler chicken were divided into two groups, consist of 1–3 weeks and of 4–6 weeks. It was observed that in tissues of young chicken (1–3 weeks), the accumulation of Hg were 20–30% higher than those found in elder group (4–6 weeks). The concentrations of Hg measured in different chicken tissues, leg, breast, liver and heart muscles were observed on dried basis in the range of 1.27–3.24, 1.86–3.86, 2.54–5.54 and 2.13–3.27 lg/kg, respectively collected from all five farms (Table 2). The variations in accumulation of Hg concentrations among different tissues of broiler chickens collected from five farms were observed. The maximum accumulation of Hg was observed in liver (2.54–5.54 lg/kg dry wt),
followed by breast muscles while lowest level was found in heart tissues (2.13–3.27 lg/kg) (Table 2).
Significant differences (p < 0:05) in Hg concentrations in different tissues of broiler chicken were apparent when comparing them on basis of different farms (Table 2). The data suggested that the
accumulation of Hg in tissues of broiler chicken was related to spatial differences of Hg in feeds. A significant difference in mean values of Hg was observed in different tissues of younger broiler
chicken (1–3 weeks) (P = 0.016) as compared to older group. Variations in accumulation of Hg in different tissues of broiler chicken of both age groups collected from different farms are shown in
Fig. 1a and b. Significant linear relationships were obtained between the Hg concentrations in feeds and different tissues, in liver (r = 0.93), breast muscles (r = 0.90) and heart (r = 0.69) (Table 3). 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).
