Atmospheric concentrations, occurrence and deposition of persistent organic pollutants (POPs) in a Mediterranean coastal site (Etang de Thau, France) ArchiMer
Castro-jimenez, J.; Mariani, G.; Vives, I.; Skejo, H.; Umlauf, G.; Zaldivar, J. M.; Dueri, Sibylle; Messiaen, Gregory; Laugier, Thierry.
Atmospheric concentrations and deposition fluxes of PCDD/F and PCB have been evaluated over a 1-year period in a Mediterranean coastal lagoon (Etang de Thau, France). Indicative PBDE air concentrations in the hot season are also reported in this work. ∑2,3,7,8-PCDD/Fs and ∑18PCBs (gas + particulate) air concentrations ranged from 67 to 1700 fg m−3 and from 13 to 95 pg m−3, respectively whereas ∑8PBDEs (gas + particulate) summer time levels varied from 158 to 230 pg m−3. The PCDD/F and PCB atmospheric occurrence over Thau lagoon and subsequent inputs to the surface waters are determined by an assemble of factors, being the seasonality of atmospheric concentration, the air mass origin and meteorological conditions important drivers. Total (wet + dry)...

Contamination chimique du milieu marin : de la mesure à l'évaluation des risques ArchiMer
Abarnou, Alain.
This activity report entitled (“Chemical contamination of the marine environment: from measurement to risk assessment”) summarizes the main stages my career at Ifremer from November 1975 to june 2013. The first chapter deals with the seawater chlorination and chlorinated waters released into the sea, the identification and the conditions of the formation of various by-product of these processes. The second chapter concerns PCBs, their nature, their chemical analysis in environmental matrices. PCBs are considered as the best examples of persistant and bioaccumulable compounds and therefore, in all this report they are flagship contaminants to which other groups of studied substances are compared. The third chapter refers to studies performed within marine...

METROC : évaluation des apports de contaminants chimiques de la métropole marseillaise au milieu marin ArchiMer
Jany, Cassandre; Zebracki, Mathilde.
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...

Utilisation d’espèces halieutiques exploitées comme indicateurs de la contamination chimique en zone littorale ArchiMer
Abarnou, Alain.
The concept of biological indicator relies upon the assumption that the contamination measured in biological tissues reflects that of the aquatic environment. This study aims to update the knowledge on contamination levels of various chemical contaminants in a few exploited fish species from various areas along the French coastline. The objective of the work is to evaluate the possibility of differentiating the various coastal zones according to the contamination levels measured in fish living there. Several groups of contaminants were followed: PCBs (marker PCBs and dioxin-like PCBs), dioxins (PCCDs and PCDFs), PBDEs, PFCs and total mercury). These contaminants were mainly measured in four fish species: the sea bass (Dicentrarchus labrax), the mackerel...
