Abstract:
:Concentrations of Zn, Pb, Cu and Cd have been determined in leaves, stems and roots of Spartina maritima and Halimione portulacoides from the Tagus estuary salt mash (Corroios) and in the sediments between their roots. Biological materials and sediments were sampled every 2 months, between July 1991 and July 1992. Root biomass increased from July to September and from January to March. The greatest metal concentrations occurred in the roots, with lowest levels in January and increasing levels during the growth periods. Zn, Pb and Cu in sediments exhibited a corresponding change in concentrations, reaching maximum in January and subsequently decreasing in spring. The ratios between metal concentrations in the root and in sediments were higher for H. portulacoides when compared to S. maritima, whose roots are surrounded by a more acidic and reduced sediment environment. It was concluded, therefore, that H. portulacoides is a more effective accumulator of metals than S. maritima, and both root-sediment systems exhibited a seasonal variation of metal concentrations.
