dc.description.abstractThe relationship between estimated daily traffic volume and the concentrations of the heavy metal pollutants, lead, cadmium, nickel, copper and chromium as determined by atomic absorption spectroscopic technique in soil, vegetation and water samples taken along sides of some major roads in seven state capitals in Nigeria has been established. The amounts of these metals in soil samples from three petrol stations in Zaria, the car park at the Kashim Ibrahim Library of the Ahmadu Bello University and that at the Advanced Teachers' College, Zaria and the Ahmadu Bello University Staff School, Samaru have been determined. Lead, Cadmium and Copper concentrations in soil and vegetation samples show significant correlation with estimated daily traffic volumes. Correlation coefficients for the concentrations of nickel in soil, chromium in vegetation and cadmium in water are also significant. However, correlation coefficients for Lead, Nickel and Chromium concentrations in water samples are not significant . The distribution of all the metals in the soil, vegetation and water samples except for nickel in vegetavi tion samples show a decrease in concentration with increasing distance from the road in all the state capitals. The metal concentrations in soil samples were generally below threshold limits. The Lead concentrations in vegetation samples in all the state capitals except Calabar, exceed the specified limits. Nickel concentrations in water samples also exceed the threshold limit in all the state capitalsen_US
