The effects of decanted sediments on embryogenesis in oysters ( Crassostrea gigas )
Abstract Sediments act as sinks for contaminants of natural and anthropogenic origin, constituting a risk to the living organisms. In this study, sediments were collected from three sites on the coast of southwest France. The objective of this research was to determine the effects of sediments on em...

Abstract Sediments act as sinks for contaminants of natural and anthropogenic origin, constituting a risk to the living organisms.
