Resumen:
Concentrations of Cd, Cu, Fe, Pb, and Zn were determined in soils and in below- and above-ground structures ofSpartina densiflora in a Patagonian salt marsh (San Antonio, Río Negro, Argentina). Also, the relationship betweentrace metal concentrations in soils and plants was investigated to improve our knowledge regarding the ability ofthis plant species to take up and accumulate trace metals from the soil. Our results indicate that, within the stud-ied salt marsh, soil trace metal concentrations follow a decreasing concentration gradient toward the sea. Theyshow moderate pollution and a potentially negative biological effect in one site of the salt marsh. Whilebelow-ground structures reflect the soil metal concentration pattern, this is not so evident in above-ground con-centrations. Also, S. densiflora is able to absorb a limited amount of metals present in the soil, the soil bioaccumu-lation factor being lower in sites where soil metal concentration is higher.
