210Po and 210Pb trophic transfer within the phytoplankton–zooplankton–anchovy/sardine food web: a case study from the Gulf of Lion (NW Mediterranean Sea) ArchiMer
Strady, Emilie; Harmelin-vivien, Mireille; Chiffoleau, Jean-francois; Veron, Alain; Tronczynski, Jacek; Radakovitch, Olivier.
The transfer of 210Po and 210Pb in the food web of small pelagic fishes (from phytoplankton and zooplankton to anchovy Engraulis encrasicolus and sardine Sardina pilchardus) is investigated in the Gulf of Lion (GoL). We present original data of 210Po and 210Pb activity concentrations, C and N stable isotope ratios, measured (i) from different size classes of phytoplankton and zooplankton during spring and winter in different environments of the GoL, and (ii) in two fish species. Significant spatial patterns based on 210Po, 210Pb activity concentrations and 210Po/210Pb ratios in the different plankton size classes are evidenced by hierarchical clustering, both in spring and winter. This variability, also observed for C and N stable isotopes ratios, is...

Biomonitoring along the french coastline: could mercury isotopic composition indicate a temporal change in hg reaching the coastal zone? ArchiMer
Briant, Nicolas; Chouvelon, Tiphaine; Brach-papa, Christophe; Chiffoleau, Jean-francois; Savoye, Nicolas; Sonke, Jeroen; Knoery, Joel.
Mercury (Hg) is a natural element toxic to all living organisms. Its ocean biogeochemical cycle is dominated by atmospheric deposition, which human activities contribute to disrupt signi cantly, and to a lesser extent by riverine discharge. This element is bioamplifed and bioaccumulated in marine food webs. since mercury concentrations in some coastal animal species of high trophic level approach sanitary thresholds, understanding biogeochemical processes and mechanisms leading to these elevated Hg concentrations becomes important. The stable isotopic geochemistry of metal is indeed a very promising way to trace processes and transfers from one mercury biogeochemical reservoir to another (Sonke and Blum, 2013). The stable isotopes of Hg undergo...

Changes in the sediment trace metal contamination after the commissioning of a municipal wastewater treatment plant in the Souss estuary (South Morocco) ArchiMer
Moukrim, A; Chiffoleau, Jean-francois; Cheggour, M; Burgeot, Thierry.
Monthly samples of sediment were collected from the Souss estuary, to determine the changes which have occurred in the concentrations of ten metals between 2001 when the low estuary was receiving the wastewaters from Agadir city and 2003 after stopping the sewage dumping. The annual contents of Cu, Fe, Zn (in 2001) and those of Cr, Cu, Fe, Mn, Ni, Pb, and Zn (in 2003) showed significant correlations with those of Al, indicating that fluctuations of their concentrations were only due to those of the aluminosilicate fraction of the clayey sediment. After normalization of these metallic concentrations in relation to those of Al, the contents of the different metals showed insignificant correlations between both years, except for Zn which significantly dropped...

Chemical contamination and sediment toxicity along the coast of Corsica ArchiMer
Galgani, Francois; Chiffoleau, Jean-francois; Orsoni, Valerie; Costantini, Louis; Boissery, P; Calendini, S; Andral, Bruno.
Trace metals (Cd, Pb, Cu, Cr, Ni, Co, Zn, Hg, As, Mn, Al, Fe, and Li) and organic compounds (PCBs, PAHs, lindanes, and DDT and its degradation products) were measured in coastal sediment samples from 27 sites in lagoons and along coastal areas of Corsica. An oyster embryo bioassay evaluated the toxicity of sediments from sites in three coastal lagoons (Urbino, Diane, and Biguglia) and the west coast of Cape Corsica. Despite contamination levels generally lower than those in other Mediterranean coastal areas, contamination is found in specific sites in Corsica and includes natural arsenic contamination on the east coast, insecticide pollution (persistent lindane and DDT) in many areas, both cadmium and lead contamination around Sagone, general contamination...

Chronology and sources of trace elements accumulation in the Rhône pro-delta sediments (Northwestern Mediterranean) during the last 400years ArchiMer
Cossa, Daniel; Fanget, Anne-sophie; Chiffoleau, Jean-francois; Bassetti, M-a; Buscail, R.; Dennielou, Bernard; Briggs, K.; Arnaud, M; Guedron, S.; Berne, Serge.
The Rhône pro-delta sediments receive the particulate inputs from the Rhône River, the largest freshwater discharge of the Western Mediterranean Sea. Trace element (TEs: Ag, Cd, Co, Cr, Cu, Ni, Pb, and Zn) concentrations and stable Pb isotope ratios were determined along a 7.7-meter-long sediment core collected from the Rhône prodeltaic lobe, archiving the deposits of the last 400 years. Trace element mean concentrations during the pre-industrialized era (before 1850 AD) were no different from the average composition of Earth’s upper crust, except for Cr. Principal component analysis, performed on TEs and tracers, suggests three origins for TEs that we identified as (i) marine biogenic material (Ag, Cd), (ii) ultramafic rocks (Li, Cr, Ni), and (iii) other...

Diagnostic de la contamination chimique de la faune halieutique des littoraux des Antilles françaises. Campagnes 2008 en Martinique et en Guadeloupe ArchiMer
Bertrand, Jacques; Abarnou, Alain; Bocquene, Gilles; Chiffoleau, Jean-francois; Reynal, Lionel.
During the years 1972-1993, kepone a persistent pesticide has been used in the banana fields of the French West Indies (Martinique and Guadeloupe) to content a weevil. A slow desorption of the molecule from soil induces its transfer to the sea through the rivers from leaching and erosion. This study intended to take stock on the contamination by kepone of the fishery species around the islands fifteen years after the kepone ban. Furthermore other chemical pollutants were sought in fish and shellfish around the Martinique island. The results confirmed persistence of marine fauna contamination by kepone, mainly in the alluvium areas in front of polluted rivers. They shown also that this contamination may spread more widely but with fast decreasing through...

Distribution of Cd and Hg in the Bay of Marennes-Oléron ArchiMer
Gonzalez, Jean-louis; Boutier, Bernard; Chiffoleau, Jean-francois; Auger, Dominique; Noel, Joelle; Truquet, Isabelle.
The study of Cd and Hg distribution in the sediments, water and suspended matter of the Bay of Marennes-Oléron provided the opportunity to identify the factors governing the distribution of these two contaminants throughout the bay. On one hand, these elements are associated with the continental inputs from the Charente river which settle on arrivaI at the mouth of the estuary and in the eastern part of the bay. The Cd and Hg present in these deposits are associated with POC, as weIl as with Mn and Fe oxides and hydroxides. On the other hand, a portion of the dissolved inputs is recycled in the bay waters through phytoplankton activity. This mechanism contributes, particularly in the case of Cd, to increased particulate metal fluxes from the water column...

Distribution of silver in mussels and oysters along the French coasts: Data from the national monitoring program ArchiMer
Chiffoleau, Jean-francois; Auger, Dominique; Roux, Nathalie; Rozuel, Emmanuelle; Santini, Anne.
Distribution and behavior of many trace elements in the aquatic environment has been well characterized, but little is known about silver (Ag) concentrations in coastal waters, even though this element ranks among the most toxic to marine invertebrates (Calabrese et al., 1977 ; Fisher and Hook, 1997 ; Webb and Wood, 1998). Studies conducted by Flegal et al. (1995), River-Duarte et al. (1999), and Ndung'u et al. (2001), provided the first valuable data on Ag distribution in the oceanic environment, indicating that this element is found in very low concentrations in the dissolved phase. However, although silver concentrations in coastal waters do not reach the nanomolar range (Smith and Flegal, 1993 ; Squire et al., 2002), formation of a stable chloro...

Port activities require continuous or occasional dredging of considerable quantities of sediments : approximately 50 million m3 along the French coastline. A large proportion of the dredgings is authorized for dumping at sea in geographically delimited areas and following an impact evaluation of their potential harmfulness to the marine environment. The environmental risks assessment linked to dredging operations relies on knowledge related to several scientific disciplines contributing to changes in the regulations. This work, intended both for managers and for environmental scientists and engineers, is designed to take stock of the current state-of-the-art in the field of sediment contamination and related ecotoxicological hazards, along with a review of...

Etat chimique des sédiments et influence d'une extraction de granulats sur l'état chimique de l'eau de mer dans le cadre du PER GMH - Etude SCOOTER. Etude sur la remobilisation de Sédiments potentiellement COntaminés induite par une OpéraTion d’ExtRaction de granulats en baie de Seine ArchiMer
Menet-nedelec, Florence; Chiffoleau, Jean-francois; Riou, Philippe; Maheux, Frank; Pierre-duplessix, Olivier; Rabiller, Emilie; Simon, Benjamin.
Dans les mers côtières où les données des réseaux de surveillance montrent que les sédiments fins en surface contiennent des contaminants, la remobilisation de ces matériaux à l’occasion d’extractions de granulats, qui génère un panache turbide, pourrait influencer la qualité de l’eau. La baie de Seine orientale est sous l’influence du panache de la Seine, l’un des fleuves les plus contaminés d’Europe. Cette étude avait pour objectif d’examiner la remobilisation des métaux traces et de contaminants organiques des sédiments vers la surface pendant et après une extraction de granulats à travers leur comportement entre la fraction totale et dissoute. Pour cela, l’expérimentation a été réalisée lors d’un essai d’extraction dans le cadre du Permis Exclusif de...

Evaluation du descripteur 8 « Contaminants dans le milieu » en France Métropolitaine. ArchiMer
Mauffret, Aourell; Chiffoleau, Jean-francois; Burgeot, Thierry; Wessel, Nathalie; Brun, Melanie.
Good Environmental Status (GES) for descriptor 8 of MSFD is reached when concentrations of contaminants are at levels not giving rise to pollution effects. According to the decision 2017/848/CE, descriptor 8 is defined by four criteria: concentration in the relevant matrices (sediment, biota) (D8C1), effects of chronic contamination to the marine organisms (D8C2), duration and spatial extent of acute pollution events (D8C3), effects of acute contamination to the marine organisms (D8C4). The GES for descriptor 8 is assessed at the level of four marine subregions (SRM), including: Channel – North Sea (MMN), Celtics Seas (MC), Bay of Biscay (GdG) and the Occidental Mediterranean Sea (MO). In order to achieve GES, each indicator of descriptor 8 should respect...

Evidencing the Impact of Coastal Contaminated Sediments on Mussels Through Pb Stable Isotopes Composition ArchiMer
Huy Dang, Duc; Schafer, Jörg; Brach-papa, Christophe; Lenoble, Veronique; Durrieu, Gael; Dutruch, Lionel; Chiffoleau, Jean-francois; Gonzalez, Jean-louis; Blanc, Gerard; Mullot, Jean-ulrich; Mounier, Stephane; Garnier, Cedric.
Heavily contaminated sediments are a serious concern for ecosystem quality, especially in coastal areas, where vulnerability is high due to intense anthropogenic pressure. Surface sediments (54 stations), 50 cm interface cores (five specific stations), river particles, coal and bulk Pb plate from past French Navy activities, seawater and mussels were collected in Toulon Bay (NW Mediterranean Sea). Lead content and Pb stable isotope composition have evidenced the direct impact of sediment pollution stock on both the water column quality and the living organisms, through the specific Pb isotopic signature in these considered compartments. The history of pollution events including past and present contaminant dispersion in Toulon Bay were also demonstrated by...

First record of butyltin body burden and imposex status in Hexaplex trunculus (L.) along the Tunisian coast ArchiMer
Lahbib, Youssef; Abidli, Sami; Chiffoleau, Jean-francois; Averty, Bernard; El Menif, Najoua Trigui.
We have assessed for the first time the current status of tributyltin (TBT) contamination in Hexaplex trunculus along Tunisian coastal waters. Two sampling campaigns have been performed in July 2004 and July 2007 at seven different sites. The snails were analyzed for imposex status, i.e. Imposex incidence, Relative Penis Length Index (RPLI) and Vas Deferens Sequence Index (VDSI), followed by the quantification of butyltins in their tissues. Imposex was detected in six populations from the 2004 samples and in five populations from the 2007 samples. The imposex incidence ranged from 0 (no imposex) to 100%, the RPLI from 0 to 56.7 and the VDSI from 0 to 4.4. TBT was also detected in six populations in 2004 and five populations in 2007. The concentrations...

Hydrocarbon pollution along Moroccan coasts and BPH activity in the mussel Perna perna ArchiMer
Azdi, M.; Moukrim, A.; Burgeot, Thierry; Budzinski, H.; Chiffoleau, Jean-francois; Kaaya, A.; Zekhnini, A.; Narbonne, J. F.; Guarrigues, Ph..
Specimens of the mussel Perna perna were collected along Moroccan coasts to determine the concentrations of polycyclic aromatic hydrocarbons ( PAHs) bioaccumulated in the tissues, and to measure benzo[ a] pyrene hydroxylase (BPH) activity. Chemical analysis of PAHs show that the Mediterranean (Nador, Martil, Tanger) and central Atlantic coasts ( from Rabat to Jorf Lihoudi) are those most contaminated ( 351 245 ng.g(-1) dry weight in Tanger). The mussel contaminants were of mixed origin for most of the locations with non negligible inputs of petrogenic origin in many of them. Baseline levels of PAHs were between 6 and 55 ng.g(-1) dry weight. BPH activity showed significant correlation (r(s) = 0.64, P < 0.05) with total PAH concentrations at the six most...

Imposex and butyltin concentrations in snails from the lagoon of Bizerta (Northern Tunisia) ArchiMer
Lahbib, Youssef; Abidli, Sami; Chiffoleau, Jean-francois; Averty, Bernard; Trigui El Menif, Najoua.
Imposex and butyltin concentrations were assessed in Hexaplex trunculus, Conus mediterraneus, Cyclope neritea and Nassarius mutabilis from Menzel Jemil, and H. trunculus and Stramonita haemastoma from the Bizerta channel. All females of the five species exhibited the characteristic development of male sex organs (penis and/or vas deferens). In Menzel Jemil, H. trunculus and C. mediterraneus exhibit similar imposex levels and were most affected (VDS reading 3-4). The development of a bud penis or a vas deferens sequence behind the right ocular tentacle was reported in Cyclope neritea and N. mutabilis (VDS 1). The concentration of tributyltin (TBT) was similar for the four species. The monobutyltin (MBT) was only detected in C. mediterraneus while the...
