Larval stages of bivalve molluscs are highly sensitive to pollutants. Oysters from a hatchery from Normandy (English Channel) were induced to spawn, and fertilized eggs were exposed to copper or cadmium for 24 h. Metal accumulation (from 0.125 to 5 m

Crassostrea gigas D-shaped larvae were subjected to different conditions of temperature and salinity for 24 h and four biomarkers (acetylcholinesterase (AChE) activity, thiobarbituric acid reactive substances (TBARS) levels, glutathione S-transferase

Surface sediment samples from 10 coastal locations were analyzed with respect to their physical and chemical characteristics as well as their biological quality. The toxicity of the decanted fresh and freeze-dried sediments and of their elutriates wa

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 con- centrations tested were always lower than the threshold at which

The release, bio-availability and toxicity of contaminants, when sediments are resuspended have been examined, studying concurrently their effects on the embryogenesis and on the larval growth of the Crassostrea gigas larvae and their bio-accumulatio

Embryos and larvae of bivalves are frequently used in marine ecotoxicology for the purpose of assessing seawater quality, because they are very sensitive to pollutants and provide rapid responses. Laboratory studies, however, cannot accurately simula

The respective sensitivity of oyster ( Crassostrea gigas ) and sea urchin ( Paracentrotus lividus ) embryos and larvae to salinity, and to various micropollutants (four heavy metals, three pesticides) and to two polluted sediments were compared with

The effects of temperature and duration of storage on the toxicity of estuarine sediments were investigated with the Crassostrea gigas oyster embryo bioassay. Sediments ranging from unpolluted (controls) to extremely polluted with heavy metals (>100

A simplification of the standard bivalve embryo-larval bioassay method for seawater quality assessment is described. Methodological features aimed to increase reliability, sensitivity and accuracy, and to reduce time and costs, include: induced natur
