The samples were treated and prepared according to Indian standard IS 14703-1999, and the measurements have been done by using inductively coupled plasm – atomic emission spectroscopy (ICP-AES) available in the Libyan Petroleum Institute. The analysis indicated that the concentration of Arsenic of all the samples was less than 0.02mg/kg whereas, the concentration of lead is less than 0.03mg/kg. The concentration ranges of Cu, Fe and Zn were 0.11-0.59mg/kg, 0.72-2.67mg/kg and 0.08-0.28mg/kg respectively.
