Abstract
Abstract In present research work concentrations of selected metals (copper, zinc, cadmium, lead, manganese and nickel) were measured in 60 dairy feed samples collected from urban and rural areas of District Jamshoro Sindh by applying atomic absorption spectrophotometer (AAS). Significantly higher levels of Cu, Zn, Cd, Pb, Mn and Ni were obtained in dairy feeds collected from urban areas of Jamshoro. Mean levels of metals in dairy feeds were in the order of Zn>Cu>Pb>Cd>Mn>Ni and Zn>Cu>Cd>Ni>Pb>Mn in both areas. Furthermore it was observed that levels of all selected metals were within their recommended ranges in both areas. Significantly negative association for Zn-Cd (r=-o.463), Zn-Mn (r=-0.349) and Zn-Cd (r=-0.361) and Zn-Ni (r=-0.377) positive association for Cd-Mn (r=0.307) and Mn-Ni (r= 0.22) were found in between the concentrations of metals in both areas dairy feed samples. In cluster analysis (CA) metals were grouped in three main clusters indicating their same source of origin.
