The pollution of metals and metalloids in soils caused by industrial activities is a major issue and invests the wholeplanet earth. The area we investigated is present in the Petrochemical of Porto Torres (Sardinia-Italy), which has anextension of about 1100 ha, is located along the northwest coast of Sardinia, about 1.8 km west of the town and witha surface contamination (0-50 cm depth) from As, Tl and V. The aim of this study is the investigation of spontaneousspecies present in the areas and the possibility to find some species among those useful to the phytoremediation. Wealso evaluate (mesocosm) some species that spontaneously live in the Porto Torres area but not on the area underconsideration such as Dittrichia viscosa and Piptatherum miliaceum which, according to literature data, showed a goodattitude towards phytoremediation. In conclusion, Dittrichia viscosa, Piptatherum miliaceum and Bromus madritensis aregood candidates to build a phytoremediation design.
