Abstract :
The present work reported here was conducted to detect the deposition of lead (Pb) from the environment in chickens. The considered samples were muscles, liver, kidney, brain, bone and poultry litter. Twenty samples of each category were collected from different locations of major cities and districts of Bangladesh. The collected samples were digested by acid digestion procedures. The detection procedures were operated by Flame Atomic Absorption Spectrophotometric Analysis (FAAS) with Zeeman background correction by subtracting the mean value of blank sample. The analysis of variance of mean Pb concentration in different samples collected from different locations differed significantly (P < 0.01).The highest concentration of lead (Pb) was found in bone (0.096±0.048mg/kg), followed by brain (0.085±0.044mg/kg), kidney (0.077±0.007mg/kg), liver (0.053±0.011mg/kg) and muscles (0.040±0.0211mg/kg). The natural accumulation of Pb was significantly (P < 0.01) present in egg shell (0.251±0.032ml/kg) compared with to the yolk (0.089±0.010ml/kg) and albumen (0.066±0.003ml/kg). A significant level of (Pb) was also detected in poultry litter (0.580±0.067 mg/kg). Lead (Pb) levels in chickens meat and eggs in this study at present showed accepted level which is at present not in alarming stage but repeated consumption of lead (Pb) contaminated chicken meats and eggs may bring a serious public health hazard.
