Do differences between metal body residues reflect the differences between effects for Chironomus riparius exposed to different sediments?

Author(s) : Pery, A. , Ducrot, V. , Geffard, A. , Garric, J.
Description : Sediment characteristics are well known to interfere with toxicity, mainly through differences in terms of bioavailability. Here, with chironomids exposed to zinc in an artificial and a field sediment, we investigated the differences of zinc accumulation and of effects on the life cycle, at individu...

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

Author(s) : Geffard, A. , Geffard, O. , Amiard, J.C. , His, E. , Amiard Triquet, C.
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 metallot...

Impact du milieu urbain sur un organisme modèle : réponses biologiques chez les dreissènes transplantées dans le bassin de l'Orge

Author(s) : Bourgeault, A. , Palais, F. , Arini, A. , Biagianti-Risbourg, S. , Geffard, A. , Gourlay, C. , Pain-Devin, S. , Uher, E. , Vincent-Hubert, F.
Description : / L'objectif de cette étude était d'observer in situ l'impact des micropolluants métalliques et organiques sur des organismes aquatiques modèles (les dreissènes) ainsi que les effets toxiques associés. Cette étude a été réalisée sur le site atelier de l'Orge. Le bassin de l'Orge présente une variab...
