Popis:	Heavy metal concentration in soils from mechanic workshop areas in Keffi town, were assessed using the topsoil in the vicinity of the study area. Samples were collected along the North- East and South West transects based on the residual pathway and the undulating surface of the area at a varying distance of 1000meters from the workshop area. The results obtained showed that Zn had the highest concentration levels followed by Cu and then lead in transects of the study areas while other metals: Nickel, Chromium and Cadmium had low concentrations in the top soils of the study areas. However, non-parametric analyses of Kruskal Wallis also show the degree of concentration and relationship among the heavy metals at the study sites. Copper, Lead and Iron though are low in the top soil but are persistence in the study sites.
