ABSTRACT

The aim of this study was to determine the content, transfer factor and pollution index of lead, copper, iron and calcium in the plants samples collected from different areas. The samples were collected and prepared using standard analytical procedures and analytical grade reagents were used for digestion. Agilent 240FS AA model of fast sequential Atomic absorption spectroscopy was used for the analysis of the metal content of these samples. Ca ranged from 743.45 to 19926.94mg/kg, Fe ranged from 96.44mg/kg to 876.21mg/kg, Cu ranged from 4.41 to 30.78mg/kg and Pb ranged from 0.58 to 11.77mg/kg. TfBompai ranged from 0.07(Fe) to 3.00(Ca), TfChallawa ranged from 0.07(Fe) to 3.25(Ca), TfJakara ranged from 0.05(Fe) to 7.31(Ca), TfSharada ranged from 0.07(Ca) to 4.07(Ca) and TfWatari ranged from 0.05 to 14.55(Ca). Challawa sampling area exhibited highest mean PI value of 7.22 and Watari lowest with mean PI value of 2.11.
