The toxicology of these trace elements was reviewed and each site ranked on the basis of computed Integrated Pollution Index. Trace elements abundance in soil samples in relation to geochemical affinities and minerals mined were also investigated. The physical impacts were based on slope failures, subsidence, mine openings as well as change in vegetation.
