Abstract

The levels of cadmium and cobalt metals in Kaduna Street dusts collected from a variety of sampling sites are reported. Wide range concentrations of the metals were observed in street dust from different parts of the municipality. Their distributions were multimodal with a mean and standard deviation of 1.37 ± 0.478 and 2.624 ±0.324 µgg-1 respectively. The results agreed with inputs from highly dispersed materials of local origin. Significant correlation between cadmium and cobalt indicated that these metals in the residential areas are affected by automobile exhaust emissions and other sources of the pollutants.
