The main objective of this study was to demonstrate that the combination of different techniques and methods (sequential extraction procedure,multivariable statistical analysis and geostatistical approach) is a powerful tool for an integral evaluation of the environmental risk in areas affected by metals. To reach this objective, the degree of metals pollution (Pb, Cu, Zn, Cd, Cr and Ni) and the delimitation of risk areas using pollution indexes and a geostatistical approach were carried out. Otherwise, the identification of sources of metals and their behaviour
were evaluated using a sequential extraction procedure and a multivariable statistical analysis
