DETERMINATION OF HEAVY METALS IN LIVER, MEAT AND BLOOD OF POULTRY CHICKEN GALLUS DOMESTICUS IN KARACHI, HYDERABAD AND THATTA (SINDH)

The present study carried out to evaluate effect of some selected heavy \ud metals (Cadmium, Lead, Nickel, Zinc and Copper) in liver, meat and blood \ud of poultry chicken, Gallus domesticus. The samples of the same were \ud obtained from poultry shops of three locations i.e. Karachi, Hyderabad and \ud Thatta (cities of Sindh Province). During the study 135 samples for each \ud item liver, meat and blood were collected at random of poultry chicken, aged \ud about 8 to 10 weeks, having weight from 1.2 to 1.5 kg. \ud The mean concentrations of Cd, Pb, Ni, Zn and Cu in liver samples of \ud Karachi city were found to be 0.103 ppm, 0.317 ppm, 6.169 ppm, 8.393 ppm \ud and 1.35 ppm, respectively. \ud The mean concentrations of Cd, Pb, Ni, Zn and Cu in liver samples of \ud Hyderabad city were found to be 0.015 ppm, 0.99 ppm, 6.484 ppm, 6.005 \ud ppm and 1.861 ppm, respectively. \ud The mean concentrations of Cd, Pb, Ni, Zn and Cu in liver samples of Thatta \ud city were found to be 0.123 ppm, 1.234 ppm, 7.583 ppm, 6.044 ppm and \ud 2.254 ppm, respectively. \ud The mean concentrations of Cd, Pb, Ni, Zn and Cu in meat samples of \ud Karachi city were found to be 0.366 ppm, 1.797 ppm, 4.133 ppm, 6.414 ppm \ud and 0.363 ppm, respectively. \ud The mean concentrations of Cd, Pb, Ni, Zn and Cu in meat samples of \ud Hyderabad city were found to be 0.046 ppm, 0.991 ppm, 3.343 ppm, 4.539 \ud ppm and 0.357 ppm, respectively. \ud The mean concentrations of Cd, Pb, Ni, Zn and Cu in meat samples of \ud Thatta city were found to be 0.215 ppm, 1.47 ppm, 4.396 ppm, 4.248 ppm \ud and 0.447 ppm, respectively. \ud The mean concentrations of Cd, Pb, Ni, Zn and Cu in blood samples of \ud Karachi city were found to be 0.002 ppm, 0.207 ppm, 0.277 ppm, 3.361 ppm \ud and 0 .496 ppm, respectively. \ud The mean concentrations of Cd, Pb, Ni, Zn and Cu in blood samples of \ud Hyderabad city were found to be 0.154 ppm, 0.045 ppm, 0.472 ppm, 4.078 \ud ppm and 0.502 ppm, respectively. \ud The mean concentrations of Cd, Pb, Ni, Zn and Cu in blood samples of \ud Thatta city were found to be 0.010 ppm, 0.298 ppm, 0.206 ppm, 3.028 ppm \ud and 0.368 ppm, respectively. \ud Based on present study results, it is concluded that the samples were found \ud contaminated with Cadmium, Lead, Nickle, Zinc and Copper. The \ud contamination level of Ni and Pb exceeded the maximum permissible limits \ud recommended by the WHO and ANZFA
