Étude de la contamination mercurielle de la phanérogame marine Posidonia Océanica dans la zone d'épandage des eau usées de l'émissaire de Giens (Var, Méditerranée, France)/Study of the mercury contamination of the marine phanerogam Posidonia Oceanica in the waste water spreading area of the Giens outfall (Var, Mediterranean, France)
Résumé
The analysis of 33 samples of leaves of surviving Posidonia oceanica bed in the sewage area of the urban emissary of the gulf of Giens (Var) has shown low rates of mercury ranging from 0,03 to 0,14 ppm. The modalities of territorial distribution of rates from the emissary mouth has been studied as vell as its spacial variability at micro-local level.
