Abstract
Analyses of mineralogy, granulometry and chemistry - aluminium,cadmium, chromium, copper, iron, lead, manganese, mercury, nickel, zinc, organic carbon, total nitrogen and phosphorus - are carried out in a Mediterranean lagoon: Etang de Thau. Shell-fish breeding and tourism make the Thau basin an important place for studying the impact of pollution within a lagoon environment. The spatial distribution of the metallic elements is related to the fine fraction (< 63-mu-m) and to the organic matter concentration of the sediment. Multivariate analysis gives a global picture of the incidence of micropolluants. It reveals a boarder zone poor in metals and organic matter...
