| The study of variations in the concentration of heavy metals inside a tank filled with the water of a neighbouring lagoon has been carried out since August 1977•The analysis concerned a lagoon station and the bath built for ECOTRON program, closed to this lagoon. They deal with water, molluscs and the sediment. Inside the lagoon station, the tested molluscs are Prosobranch Gastropods : Trochocochlea carinata and inside the basin, cockles : Cerastoderma glaucum.
