1 Projet de caractérisation – GCI747
Le Bisphénol A et le triclosan dans les eaux de la rivière St-François : une préoccupation grandissante! Projet de caractérisation – GCI747 Département de génie civil 2500, boulevard de l’Université Sherbrooke (Qc) – J1K 2R1

2 Substances perturbatrices du système endocrinien
Un composé chimique exogène ou un mélange de composés qui altère une ou des fonctions du système endocrinien des organismes et qui cause des effets néfastes sur la santé des organismes vivants, sur leur progéniture ou sur une partie de la population. Vos et al., (2000), Crit. Rev. Toxicol.

3 Substances perturbatrices du système endocrinien

4 Les effets des EDCs Effets hormono-dépendants :
Estrogène (xénoestrogène); Thyroïde; Féminisation des espèces aquatiques; Diminution de l’épaisseur de la coquilles des œufs chez les oiseaux; Diminution du nombre de spermatozoïdes chez l’humain…

5 Les effets des EDCs Ovaries from white sucker (Catostomus commersoni) collected during their spawning migration. The fish on the left was from a population living in a remote undeveloped region of Lake Superior (Mountain Bay). The fish on the right was from a population living in Jackfish Bay, Lake Superior, which receives BKME from a mill at Terrace Bay, Ontario, Canada. Ovarian size was significantly reduced in fish originating from the BKME-exposed site. Pictures provided by Drs M. McMaster, K. Munkittrick, and G. Van Der Kraak.

6 Les effets des EDCs “However, essentially all of the evidence to date suggests that it is the potent steroidal estrogens that are the primary causative agents leading to feminization of fish…..” Sumpter and Johnson 2005

Constat d’échec des

11 EDCs étudiées Triclosan (TCS)
Agent antimicrobien utilisé dans les produits de soins corporels (eg. dentifrices, déodorants, savons, etc.) Relargué dans l’environnement par les effluents et les boues des usines d’épuration des eaux usées municipales Perturbations endocriniennes mal connues Perturbations du système thyroïdien [TCS]effluents jusqu’à ~ 5 µg/l; [TCS]boues ~ 55 mg/kg
