The quantitative soil contamination assessment maps (both deterministic and probabilistic) are based on soil guideline values (SGV) approach, thus the soil maps are classified on the basis of a determined regularity threshold value. In this case CLEA (2009) SGV for heavy elements Cu, Ni and Cr:130 mg/kg, Zn:300 mg/kg, Ba:400 mg/kg, and Pb:450 mg/kg (Table 1) has been chosen respectively. However, local specific statutory SGV may be used. Toxic effects associated with the ingestion of high concentrations of heavy metals are given in Table 5.
