WebContamination Evaluation based on Geoaccumulation Index The Igeo was used to calculate metal contamination level in the soils (fig. 1). The mean Igeo values for all metals ranged from -5.66 to 2.06, suggesting that some soils were not contam-inated whilst, others were moderately contaminated. The Igeo values for Pb and Zn showed Web31 dec. 2007 · The geoaccumulation index shows that the contamination of Cr, Ni, Cu, Pb, Zn and Cd is widespread in urban soils and urban road dusts of the cities. Generally, the contamination levels of Cu, Pb, Zn and Cd are higher than that of Ni and Cr. Agricultural soils are also significantly influenced by Cd, ...
