Salt-marsh areas as copper complexing ligand sources to estuarine and coastal systems

Description: 10 páginas, 3 tablas, 3 figuras , Dissolved copper levels, copper complexing capacities and conditional stability constants have been determined in the Tagus estuarine waters and one of the saltmarshes located in this estuary, the Rosario saltmarsh. Tagus estuarine waters show a constant and around 20 ...

Derivation of predicted no effect concentrations (PNEC) for marine environmental risk assessment: Application of different approaches to the model contaminant Linear Alkylbenzene Sulphonates (LAS) in a site-specific environment

Description: 6 páginas, 8 figuras, 1 tabla. Special Issue: Environmental contaminants and their effects: Links between environmental chemistry and toxicology. , Four sediment-dwelling marine organisms were exposed to sediments spiked with increasing concentrations of Linear Alkylbenzene Sulphonate (LAS). The select...

Influence of sediment acidification on the bioaccumulation of metals in Ruditapes philippinarum

Description: 10 páginas, 3 figuras, 1 tabla. , Background, aim and scope: The influence of pH (range 6.5–8.5) on the uptake of Zn, Cd, Pb, Cu, Ni, Cr, Hg, and As by juveniles of the clam Ruditapes philippinarum was examined in order to understand whether variation in sediment pH has significant repercussions on me...

Effect of tidal flooding on metal distribution in pore waters of marsh sediments and its transport to water column (Tagus estuary, Portugal)

Description: 10 páginas, 4 figuras, 4 tablas , Sediment cores and flooding water were collected at 0, 5, 10 and 50 min of tidal inundation in two sites of the Rosário salt marsh located in the proximity of a heavy industrialised zone of Tagus estuary colonised by pure stands of Spartina maritima (low marsh) and Sar...

Tidally driven N, P, Fe and Mn exchanges in salt marsh sediments of Tagus estuary (SW Europe)

Description: 12 páginas, 2 tablas, 4 figuras , Short-sediment cores and flooding water were collected at 0, 5, 15, 25 and 50 min of tidal inundation in the two sites colonised by pure stands of Spartina maritima (low marsh) and Sarcocornia fruticosa (high marsh) from the Rosário salt marsh (Tagus estuary, SW Europe...

Yttrium in the Vigo Ria (NW Iberian Peninsula): Sources, distribution, and background levels Itrio en la Ría de Vigo (NO Península Ibérica): Origen, distribución y valores de fondo

Description: 9 páginas, 3 figuras, 1 tabla. , [EN] Certain heavy minerals enriched in yttrium, such as monazite and xenotime, have previously been indexed in the Vigo area. The levels and spatial distribution of this element were studied in 50 surface sediment samples from the Vigo Ria. The highest levels were foun...

Environmental levels of Linear alkylbenzene Sulfonates (LAS) in sediments from the Tagus estuary (Portugal): environmental implications

Description: 11 páginas, 4 figuras, 1 tabla. , Sediments from the Tagus estuary (Portugal) were collected at 40 stations in July and December 2004. Total LAS concentrations ranged between 0.03 and 17.76 mg LAS·kg−1 dry weight in July, and between 0.09 and 9.57 mg LAS·kg−1 in December. Highest LAS concentrations wer...
