Assessment of nickel content in pakistani soil using faas

To establish baseline data for the detection of Nickel contamination in Pakistan, foil samples were collected from various ecological areas of the country and analysed by using flame atomic absorption spectrometry (FAAS). Measured elemental content of Ni have median value of 69. 38+-1.25mg Kg/sup -1/ and geometric mean value 69.48 + 1.53, geometric standard deviation of 69.48+-1.53 mg Kg/sup -1/. The levels ranged from 25.63+-1.25 -146.88+-6.25mg Kg/sup -1/ being lowest in Okara and highest in Faisalabad area. These levels are comparable with reported values of other countries. (author)
