Lahbib, Youssef / Abidli, Sami / Chiffoleau, Jean-francois / Averty, Bernard / El Menif, Najoua Trigui - 2009We 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...Contributeur (s):

Idardare, Zaina / Chiffoleau, Jean-francois / Moukrim, A / Alla, A / Auger, Dominique / Lefrere, L / Rozuel, Emmanuelle - 2008Metal concentrations were measured monthly during an annual cycle (December 2004 to January 2006) in the tissues of Nereis diversicolor ragworms and sediment from two Moroccan Atlantic coastal lagoons: Oualidia in the north, situated in a highly industrialised urban area and Khnifiss in the south,...Contributeur (s):

Moukrim, A / Chiffoleau, Jean-francois / Cheggour, M / Burgeot, Thierry - 2008Monthly 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...Contributeur (s):

Cozic, Amandine / Viollier, E / Chiffoleau, Jean-francois / Knoery, Joel / Rozuel, Emmanuelle - 2008Concentrations of volatile hydrogen sulfide (H2S), carbonyl sulfide (OCS), methane thiol (MeSH), dimethyl sulfide (DMS), and dimethyl disulfide (DMDS) in the Seine estuary (France) were investigated in spring 2005 using samples collected from the first meter beneath the surface. Levels of dissolved...Contributeur (s):

Anajjar, E / Chiffoleau, Jean-francois / Bergayou, H / Moukrim, A / Burgeot, Thierry / Cheggour, M - 2008Concentrations of seven metals (Cd, Cu, Cr, Pb, Ni, Zn, Hg) were monitored monthly during 2 years in two bivalves, Cerastoderma edule and Scrobicularia plana collected from the Souss estuary (South Morocco) before and after the commissioning of a sewage treatment plant in November 2002. According...Contributeur (s):

Thouvenin, Benedicte / Gonzalez, Jean-louis / Chiffoleau, Jean-francois / Boutier, Bernard / Le Hir, Pierre - 2007The Seine estuary (France) is currently one of the world's most contaminated estuaries, due in particular to its high cadmium and lead content. Proper understanding of contaminant transfer, transformation and retention mechanisms throughout the estuary and up to the adjacent marine zone...Contributeur (s):

Chiffoleau, Jean-francois / Auger, Dominique / Roux, Nathalie / Rozuel, Emmanuelle / Santini, Anne - 2005Distribution 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,...Contributeur (s):

Galgani, Francois / Chiffoleau, Jean-francois / Orsoni, Valerie / Costantini, Louis / Boissery, P / Calendini, S / Andral, Bruno - 2006Trace 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...Contributeur (s):

Gonzalez, Jean-louis / Thouvenin, Benedicte / Dange, Catherine / Chiffoleau, Jean-francois / Boutier, Bernard - 2006The role of particles in the fate and speciation of trace metals in macrotidal estuaries was studied using a surface complexation model (MOCO). Cadmium was selected as the target metal contaminant due to its reactivity in estuaries: cadmium behavior is mainly controlled by heterogeneous processes (...Contributeur (s):

Chiffoleau, Jean-francois - 1994This document constitutes a synthesis of current knowledge on the chromium biogeochemical cycle. The natural and anthropogenic sources are evaluated, the fluxes between the various geochemical compartments are assessed, with special attention to the riverine and atmospheric inputs to the marine...Contributeur (s):

Alzieu, Claude / Abarnou, Alain / Bassoullet, Philippe / Boutier, Bernard / Chiffoleau, Jean-francois / Crenn, Isabelle / Derrien, Annick / Erard-le Denn, Evelyne / Gourmelon, Michele / Guiliaud, Jean-françois / Silva Jacinto, Ricardo / Le Cann, Pierre / Le Guyader, Françoise / Le Hir, Pierre / L'Yavanc, Jacky / Mauvais, Jean-louis / Menard, Dominique / Michel, Pierre / Monbet, Yves / Pommepuy, Monique / Quiniou, Francoise - 1999Port 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...Contributeur (s):

Chiffoleau, Jean-francois / Chauvaud, Laurent / Amouroux, David / Barats, Aurélie / Dufour, Aurélie / Pecheyran, Christophe / Roux, Nathalie - 2004Levels of nickel and vanadium, trace metals found in high concentration in the oil spilled from the "Erika" tanker off Brittany (France) in December 1999 (41 +/- 1 and 87 +/- 3 mg kg(-1) respectively), have been monitored over a one-year period following this accidental event in several...Contributeur (s):
