To evaluate marine sediment quality in the Gulf of Cádiz, chemical concentration and toxicity test endpoints from sediments were linked using multivariate analysis. Sediment samples were collected synoptically at seven stations in two littoral ecosy

The level of contamination in sediments from several sites on the coast of Galicia (Spain) diversely affected by the Prestige oil spill was evaluated 18 months after the accident. Data of metal and total hydrocarbon concentrations in sediments were i

The results of an interlaboratory assessment made to evaluate the use of different bioassays for sediment quality characterization for a regulatory purpose are presented. The objective of the study was to determine the main differences among sediment

Interlaboratory variability was studied for the bioassay using crustacean amphipods. Nine series of data were obtained from different laboratories using four different species (Ampelisca brevicornis, Corophium volutator, Corophium multisetosum and Mi

The Microtox® bioassay was tested in an interlaboratory study to evaluate the variability when using solid-phase samples. The exercise consisted of two consecutive phases each one carried out with six sediment samples from Spanish ports. Phase I inc

To ensure that toxicity bioassays comply with national criteria, an interlaboratory study was carried out that focussed mainly on the development, optimization and validation of methods for dredged material toxicity assessment. The performance of the

Several species of bivalves and procedures have been used to characterize sediment toxicity. Here we report the results of an interlaboratory exercise that included three different laboratories to evaluate the use of the bioassay using the commercial

Female red swamp crayfish, Procambarus clarkii, were exposed for 21 days in the laboratory to different dissolved concentrations of zinc (1000 µg L–1 and 3000 µg L–1) and cadmium (10 µg L–1 and 30 µg L–1), determined in the Guadiamar Rive

Temporal surveys at the Guadalquivir estuary were carried out between May and December 1998 to assess the behaviour of four heavy metals (Zn, Cd, Pb and Cu). These metals presented a non-conservative behaviour, with KD ranging between 102 and 104. Lo

The benthic fluxes of inorganic carbon were measured in the Bay of Cádiz, located in the SW of the Iberian Peninsula (Southern Europe). The values measured ranged between 74 and 224 mmol m–2 d–1, which are higher than most reported fluxes. They
