Description
METROC program (part of the MEDICIS program about study and fate of the chemical contamination in Western Mediterranean Sea) focuses on sources and wastes issued by large metropolis, with the agglomeration of Marseille as a pilot site. This report presents the results of a sampling campaign in rivers and urban discharges in Marseille and on different types of contaminants (metals, PAH, PCB and PBDE) in dissolved and particulate phases, in dry and rain periods. Results show that concentrations of pollutants are greater in Aygalades river (metals and organic contaminants) and in Emissaire 2, sewer overflows and torrents. From the results of the analysis and discharge given by the DEA, we estimated partially the flows of pollutants which show that the first contributor is the Emissaire 2 (mainly because of the amount of water discharge). The second contributor is the Huveaune river. The Aygalades are not relevant anymore, neither the sewer outflows. Advice are given, based on this project experience, if the campaign should be pursued.
