This paper reports on the speciation of heavy metals (Cd, Pb, Cr, Cu, Ni, Mn, Fe, and Zn) in the surface water dissolved fraction of the low basin and plume of the Manzanares River, in the state of Sucre, Venezuela, based on data taken at 22 stations from July 1996 to June 1997. The total metal concentrations in the dissolved phase ranged from below detection levels to 0.01, 0.02, 0.02, 0.10, 0.10, 1.03, 2.56, and 5.13 μmol L–1 for Cd, Pb, Cr, Cu, Ni, Mn, Fe, and Zn, respectively. Overall, the…

Benthic prey quantity and quality in the main mudflat feeding areas of the Tagus Estuary: Implications for bird and fish populations
Estuaries are among the most productive environments in the coastal zone that may act as sink of pollutants. In this study we evaluated how levels of heavy metal contamination can be reflected in the
Biochemical and histopathological endpoints of in vivo cadmium toxicity in Sparus aurata Respuestas bioquímicas e histopatológicas a la toxicidad por cadmio in vivo en Sparus aurata
A histological technique using a fluorochrome (acridine orange) to enhance tissue detail is described, as well as a method suitable for the detection of MTs in SDS-PAGE gels with a colloidal Coomassie blue stain, which confirmed the suitability of S. aurata as a test organism regarding toxicity caused by Cd.

The Conservative Behaviour of Trace Metals (Cd, Cu, Ni and Pb) and As in the Surface Plume of Stratified Estuaries: Example of the Rh ône River (France)
Abstract Concentrations of dissolved trace elements (Cd, Cu, Ni, Pb and As) were determined over a 4-year period (1987 –91) during contrasting hydrological conditions in a typically stratified
Biogeochemical cycling of nutrients and trace metals in anoxic freshwater sediments of the Neckar River, Germany
Pore-water components (SO42-, Fe2+, Mn2+), including nutrients (NH4+:, NO3-, PO43-), alkalinity and pH were determined at three sites in the Neckar River. Sequential extraction procedures and trace
The accumulation and distribution of trace metals in some localized marine species
Some species showed a high affinity toward certain elements, and their levels of accumulation in the tissues of these species corresponded with the concentration of these elements in sediments, especially at sites in the vicinity of an industrial zone.
