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