Determination of some heavy metals in groundwater and table water in Tudun Murtala, Nassarawa Local Government Area, Kano-Nigeria

Abstract

This study determine the level of heavy metals (Pb, Cd, Cr, Zn, Fe) in water samples obtained from different sources (well water, borehole water and table water) in Tudun Murala, Nassarawa local government area, Kano state. The concentrations of heavy metals in the water samples were determined using flame Atomic Absorption spectrometer. Results showed that the concentration of Pb, Cd, Cr and Fe in water samples were within the range: 0.295- 0.579, 0.471- 0.529, 0.550- 1.000, 0.3636 - 0.4545mg/l respectively, which were above the permissible limits set by WHO. Whereas the concentration of Zn (0.0814 - 0.173) was within the limit set. The elevated concentration of heavy metals could be linked to environmental factors and industrial pollution in the area.
