Toxicite potentielle des sediments marins et estuariens contamines : evaluation chimique et biologique, biodisponibilite des contaminants sedimentaires Potential toxicity of the marine sediments and estuariens contaminate: chemical and biological evaluation, biodisponibility of the sedimentary contaminants

Author(s) : Geffard Olivier
Description : Marine and estuarine sediments concentrate various pollutants. Thus, they can constitute a risk of contamination for aquatic organisms, and cause a public health problem. The potential toxicity of various sediments was studied by different bioassays and by assessing the bioavailability of polycyclic...

Relationships between metal bioaccumulation and metallothionein levels in larvae of Mytilus galloprovincialis exposed to contaminated estuarine sediment elutriate

Description : The bioavailability of Cd, Cu and Zn from a metal-contaminated sediment was studied using Mytilus galloprovincialis embryos and larvae exposed to sediment elutriates, The elutriate concentrations tested were always lower than the threshold at which abnormal larval development appears. The Cd, Cu and...

Utilisation d'une série temporelle de données-satellite NOAA-AVHRR pour le suivi hydrologique des grands fleuves en Afrique de l'Ouest Interactions surface continentale/atmosphère : l'expérience HAPEX-Sahel

Author(s) : Geffard, Sophie
Description : L'intérêt d'utiliser les informations tirées des données-satellite NOAA-AVHRR dans le cadre du suivi du régime hydrologique des fleuves en Afrique de l'Ouest est évalué au travers de la confrontation entre la dynamique saisonnière des indices radiométriques et le bilan hydrologique annuel. Les bassi...

Bioaccumulation of metals in sediment elutriates and their effects on growth, condition index, and metallothionein contents in oyster larvae

Description : The bioavailability of Cd, Cu, Zn, and Pb from two metal-contaminated sediments (Bidassoa and Dunkerque) was studied using Crassostrea gigas larvae exposed to sediment elutriates. The metal contents within the sediments, the larvae and larval growth, the condition index, and the induction of metallo...
