Étude écotoxicologique en milieu aquatique du Mexel 432, substance antisalissure : Optimisation d'un test écophysiologique basé sur les activités filtrante et valvaire de Dreissena polymorpha application à la lutte contre ce mollusque

Abstract : Laboratoty studies on the short-term lethal toxicity of the Mexel 432 have lead to a response classification of differente species, which is, by decreasing sensibility : Daphnia>Gammarus>Dreissena>Anodonta>Corbicula>Chironomini* (*without dose/effect relation). According to these results, residual concentrations lower then 3mg/l could be used in sequential tratments lasting short periods (less than one hour). In case of continuous treatments, residual concentrations lower than 0,20 mg/l could be recommended in order to save organisms not targeted by the compound. Laboratory sublethal toxicity tests, using the 'filtrovalvomètre' have permitted to classify several antifouling substances by their toxicity on pumping and valve activity and also to improve the use of the biomonitoring. The classification, by increasing toxicity is : Mexel 432
