2 Why studying effluent dissolved organic matter (Ef)? Part of from WWTP (%) Water flow (m3/s) Organic matter from WWTPs Present in anthropized aquatic environment 10 to 60% of the in the Seine River is from the WWTP depending on the flow (low-flow period) oct-10 nov-10 janv-11 févr-11 mars-11 avr-11 mai-11 juin-11 sept-11 0 Matar et al.

3 Why studying effluent dissolved organic matter (Ef)? Organic matter from WWTPs Present in anthropized aquatic environment 10 to 60% of the in the Seine River is from the WWTP depending on the flow (low-flow period) Physico-chemical properties different from natural More hydrophilic 20 to 40% of hydrophilic before Paris 50 to 55% of hydrophilic after Paris from river Ef Pernet-Coudrier et al.

4 Why studying effluent dissolved organic matter (Ef)? Organic matter from WWTPs Present in anthropized aquatic environment 10 to 60% of the in the Seine River is from the WWTP depending on the flow (low-flow period) Physico-chemical properties different from natural More hydrophilic 20 to 40% of hydrophilic before Paris 50 to 55% of hydrophilic after Paris More nitrogen and sulfur groups Lower molecular weight Pernet-Coudrier et al. (2011) Biogeochemistry 106:
5 Why studying effluent dissolved organic matter (Ef)? Strong influence on the speciation of the trace metals 80 to 90% of lead and mercury are binded to Ef after Paris conurbation in the Seine River Decrease of the free copper (-70%) after Paris conurbation Matar et al. (2015) Environ Sci Pollut Res 22:
6 Why studying effluent dissolved organic matter (Ef)? Strong influence on the speciation of the trace metals Strong influence on the biodisponibility of the trace metals Copper EC 50 on daphnia magnae with different Decrease of the copper biodisponibility and toxicity with Ef Matar et al.
