Foundries and electroplating industries have been investigated to improve industrial processes, reducing the external environment impact and promoting human health and welfare. There are 23 industrial plants located in the municipality of Loanda, Paraná, Brazil. The main goal of the project was the evaluation of the soil contamination by toxic metals in the vicinities of their most profitable unit. The soil characterization was performed by physical-chemical measurements and their extractable toxic metals (Ag, Al, Cd, Cr, Co, Cu, Fe, Mg, Mn, Ni, Pb, V, Zn) content. They were analyzed after the HNO3 extraction, and also after EDTA extraction. This procedure was adopted to provide additional information about the toxic metals mobility on soil samples. According with the results, the soil is composed by sand with siliceous acid properties, with low content of clay, organic mater and cationic exchange capability. The higher extractable toxic metals concentrations were found for Cu, Zn, Cr, Ni and Pb in the boundary of the industrial plant and their vicinity. The extraction results indicate the soil toxic metals contamination can be considered stabilized with an exception for high mobility elements as Cr and Ni. It was an indication of the need of continuous monitoring and control for Cr and Ni content including periodically groundwater evaluation. Production process must be improved in order to avoid further contamination.
