n this study enrichment factor was used to assess the level of contamination and the possible anthropogenic impact in soils from the vicinity of the abundant railway servicing workshop. To identify anomalous metal concentration, geochemical normalization of the heavy metals data to a conservative element, such as Al, Fe, and Si were employed. Several authors have successfully used iron to normalize heavy metals contaminants (Baptista Neto et al., 2000; Mucha et al., 2003). In this study iron was also used as a conservative tracer to differentiate natural from anthropogenic components. According to Ergin et al., (1991) and Rubio et al., (2000) the metal enrichment factor (EF) is defined as follows
