DETECTION OF THE SOME HEAVY METALS RESIDUES IN THE LOCAL BULLS TISSUES IN KIRKUK DURING THE WINTER AND SUMMER SEASONS
AbstractFor the purpose of investigating the levels of some heavy contamination metals in muscle, liver and kidney meat for Cattle in Kirkuk governorate in winter and summer seasons, samples were collected randomly from males (aged 16-18 months) from three districts of Kirkuk governorate (Downtown, Daquq and Debs) During the December and February (winter season) and July and August months of (summer season). There was a significant effect (p?0.05) on the factors (meat type, location and season) in the concentration of lead, Kidney meat in the Downtown in the winter season recorded the highest concentration of lead and significant difference (6.678 ppm) The lowest concentration (0.881 ppm) was found in Liver in Winter. The highest concentration level of cadmium in muscle in summer season from Downtown (3.336 ppm), and lowers Concentration of cadmium (2.106 ppm) recorded in kidney from Daquq in summer season. The concentration of zinc in the Liver at the Downtown in the summer season was the highest concentration (140.052 ppm), while the Kidney in the winter season from Downtown recorded the lowest concentration (30.54 ppm). For Copper the liver in the Downtown in the winter season had the highest concentration (24.520 ppm), while the Liver from the Downtown at summer was recorded lowest concentration (2.383 ppm). For Cobalt, in winter season in Kirkuk, the Muscle recorded the highest concentration of cobalt (7.344 ppm), while the lowest concentration was recorded in Kidney the Winter season from Downtown (1.062 ppm). All types of metals recorded levels higher than the internationally accepted limits.
