Resumen:
Phytoremediation is considered the most appropriate technique to restore metal polluted soil, given its low cost,high efficiency and low environmental impact. Spartina densiflora and Sarcocornia perennis are perennial halo-phytes growing under similar environmental conditions in San Antonio marsh (Patagonia Argentina), thereforeit is interesting to compare their phytoremediation potential capacity. To this end, we compared concentrationsof Pb, Zn, Cu, and Fe in soils and in below- and above-ground structures of S. perennis and S. densiflora. It was con-cluded that both species are able to inhabit Pb, Zn, and Cu polluted soils. Although Sarcocornia translocated moremetals to the aerial structures than Spartina, both species translocated only when they were growing in soils withlow metal concentrations. It seems that the plants translocate only a certain proportion of the metal contained inthe soil. These results suggest that both species could be considered candidates to phytostabilize these metals inpolluted soils.
