Estimation of Heavy Metals in Liver, Gizzard, Breast and Thigh Muscles of Broiler Chicken in Different Area of Lahore by ICP-OES
Poultry, considered to be healthy type of meat, is the most important animal source of protein in food web. In this study, the concentration of metals in different parts of broiler chicken was determined by inductively coupled plasma optical emission spectrometry (ICP-OES). The highest mean level of nickel (43.89 ±0.87 µg/kg) was observed in gizzard muscles collected from Amin Park while lowest level (2.34 ±0.63 µg/kg) was found in gizzard samples collected from Lohari. Thigh muscle samples collected from Lohari did not show any level of nickel. The highest mean concentration of chromium was found in breast muscle samples collected from Amin Park 171.37±0.92 µg/kg while the samples collected from Outfall Road had the lowest chromium concentrations in gizzard 55.46±0.23 µg/kg. No chromium was detected in thigh muscles collected from Lohari. The maximum mean cadmium concentration calculated in liver and thigh muscles sampled from Shahdara were 52.36 ± 0.07 µg/kg and 51.46 ± 0.21 µg/kg respectively. The liver tissue samples of Amin Park had minimum cadmium concentration 28.46 ± 0.28 µg/kg. Higher level of copper among all samples was observed in thigh muscles 1.81±0.15 µg/kg collected from Outfall road, while lowest level was in breast muscle 0.10 ±0.01 collected from Shahdara. The study showed presence of wide range of heavy metals concentration (Ni, Cr, Cd and Cu) in all parts including (Gizzard, Breast muscle, Thigh muscle and Liver) of broiler chicken. All the results are within the safe limits and safe for human consumption.
