The concentrations of toxic , minor and trace elements in local Kurdish yoghurt samples collected  from   different  markets in Halabja governorate ,Kurdistan region ,Iraq were determined in this study. Results indicated that Aluminum (Al), Titanium (Ti) and  Lead (Pb) have the highest concentration among other  toxic trace elements in yoghurt samples. The concentration of these elements were 523.34 - 106.1, 438 - 325 and   4.36 – 0.4 µg kg-1 for Al, Ti and Pb respectively. Concentrations of  trace elements  Be, V, Li, Cs and Co in local yoghurt samples  were  16.63 – 2.32 , 1.33 - 0.02, 11.71 - 0.83 ,13.3 - 0.18 and   zero  µg kg-1 respectively . Zinc had the highest value among other miner elements in yoghurt samples .Zn concentration found in local yoghurt was between  5807.99 – 20945.1 μg.kg-1.
