- •
Oyster's cells volume regulation after hypo-osmotic stress (RVD) has been modeled.
- •
RVD is inhibited after a short term exposure of oysters to diesel oil.
- •
This effect is interpreted as a decreased permeability of cells membranes.
- •
In contrast, the gills Glutathione S-Transferase specific activity is unchanged.
- •
RVD inhibition could be used as a sensitive biomarker for micropollutants.
