Abstract

This work was carried out in order to determine the trace metal levels in River Benue to acertain the extent of pollution of the water body. Trace metal levels in water and sediments of River Benue were determined using the atomic absorption spectroscopy (AAS) model. The results suggest that trace metal concentrations in River Benue were generally greater in the sediment samples than water samples. Among the metals investigated Mg had the highest concentration both in water and sediment samples. The concentrations of Mg, Zn, Pb and Cr were high during dry season compared to those of Cu, Mn and Cd. Most values of the parameters studied fall within the permissible limits of WHO and NAFDAC, except for those of Pb, Cd and Cr. This may be as a result of runoff from neighboring farms as a result of rains.

 

Key words: Sediments, season, surface water, trace metal.
