PEPS LAG : Projet Echantillonneurs Passifs pour la Surveillance de la contamination chimique des LAGunes méditerranéennes ArchiMer
Munaron, Dominique; Hubert, Morgane; Gonzalez, Jean-louis; Tapie, Nathalie; Budzinski, Helene; Guyomarch, Julien; Andral, Bruno.
L’objectif de cette étude est de caractériser le niveau d’exposition des lagunes aux contaminants chimiques, complétant ainsi notre connaissance de la qualité des masses d’eau côtières méditerranéennes françaises. 23 masses d’eau de transition (soit 26 lagunes) réparties sur 7 départements côtiers en LR et PACA ont été échantillonnées au moyen d’échantillonneurs intégratifs (SBSE, POCIS et DGT) entre mai et août 2010. 141 contaminants issus de différentes familles chimiques (pesticides, médicaments, alkylphenols, HAP, PCB et métaux traces) ont été recherchés et leurs teneurs comparées aux Normes de Qualité Environnementales, lorsque celles-ci existent. La plupart des contaminants disposant d’une NQE ne la dépasse pas, à l’exception du cuivre, des...

Mise en place d’un site marin (Etang de Thau) dans le cadre de l’essai interlaboratoires sur les échantillonneurs passifs (EIL AQUAREF) - Rapport d'étape - Convention 2010 - Action 9 ArchiMer
Munaron, Dominique; Hubert, Morgane; Gonzalez, Jean-louis; Tixier, Celine.
Ce document est réalisé dans le cadre de la convention Onema-Ifremer 2010 au titre de l’action n°9 (Mise en place d’un site « marin » en Méditerranée pour l’essai inter-laboratoire (EIL) sur les échantillonneurs passifs). Cette action s’inscrit dans le programme AQUAREF 2010 et vient donc en complément de l’action n°13 de la convention Onema- Cemagref 2010 (Exercices d’inter-comparaison in situ d’échantillonneurs intégratifs. Application pour l’échantillonnage de métaux, d’hydrocarbures aromatiques polycycliques et de pesticides). Sur le fond, ces deux actions ne peuvent être dissociées, c’est pourquoi les deux rapports d’étape réalisés (dont celui-ci) présenteront inévitablement des redondances. Les difficultés liées à la mesure de micropolluants dans les...

Mercury transformations and exchanges in a high turbidity estuary: The role of organic matter and amorphous oxyhydroxides ArchiMer
Laurier, Fabien; Cossa, Daniel; Gonzalez, Jean-louis; Breviere, Emily; Sarazin, G.
The speciation and partition of mercury in a macrotidal estuary (Seine estuary, France) was studied in order to explore the role of the high turbidity zone (HTZ) in mercury transfer to the adjacent coastal waters. Water and particles were analyzed to determine the concentrations of various mercury species, including monomethylmercury and the inorganic fraction. The exchangeable particulate mercury, which varies with salinity, and the mercury fraction associated with the amorphous oxyhydroxides were evaluated. The distribution of dissolved mercury species during early mixing suggests non-conservative behavior of organically bound mercury at the head of the estuary. Mercury in the particles covaried positively with suspended particulate matter concentrations...

Passive samplers for monitoring priority micropollutants in surface waters: a national scale study ArchiMer
Mathon, Baptiste; Togola, Anne; Mazella, Nicolas; Lardy-fontan, Sophie; Dabrin, Aymeric; Ghestem, Jean-philippe; Tixier, Celine; Gonzalez, Jean-louis; Botta, Fabrizio; Miège, Cécile.
The implementation of the Water Framework Directive (WFD) requires the monitoring of micropollutants in the aquatic environments to prevent any damages to both human health and ecosystems. In this context, a number of organic and inorganic compounds have been selected as priority pollutants and their measurement is necessary to ensure that water-quality standards are maintained (EC, 2008; EC, 2013; EC, 2015). For two decades, passive sampling methods have been developed for the monitoring of organic and inorganic compounds. Passive samplers allow measuring these compounds at trace levels by accumulation and concentration over long-term exposure. Moreover, the use of integrative passive samplers (IPS) allows a better representativeness of measurements...

Pernet, Fabrice; Barret, Jean; Le Gall, Patrik; Malet, Nathalie; Pastoureaud, Annie; Munaron, Dominique; De Lorgeril, Julien; Bachere, Evelyne; Vaquer, Andre; Huvet, Arnaud; Corporeau, Charlotte; Normand, Julien; Boudry, Pierre; Moal, Jeanne; Quere, Claudie; Quilien, Virgile; Daniel, Jean-yves; Pepin, Jean-francois; Saulnier, Denis; Gonzalez, Jean-louis.
This study was conducted in the Mediterranean area during a mass mortality event of Pacific oyster Crassostrea gigas. The objectives of this work were to increase our understanding of the mass mortality phenomena in Pacific oysters, to identify risky cultivation practises and to propose mitigation strategies. In the first part of this work, we followed environmental parameters of the Thau lagoon in relation with mortality events. Then, we compared mortality and growth parameters of oysters as a function of their origins, their development stages and cultivation sites in relation with energetic, reproduction and pathogens. Finally, we conducted transfer experiments where oysters maintained free of mortality in open sea were transferred in the Thau lagoon...

Etude pilote préliminaire : Première évaluation des niveaux de contamination chimique des eaux littorales guyanaises dans le cadre de la préparation du volet "chimie" du contrôle de surveillance DCE - campagne Novembre 2008 ArchiMer
Gonzalez, Jean-louis; Tapie, Nathalie; Budzinski, Helene; Guyomarch, Julien; Crenn, Vincent; Bretaudeau-sanjuan, Jane.
L'objectif principal de cette première étude était d'évaluer, dans le contexte guyanais, l'opérationnalité de techniques d'échantillonnage et de faire une évaluation préliminaire de la contamination chimique de différentes masses d'eaux guyanaises (2 sites en eau de transition et 1 site en eau côtière). Deux types d'échantillonneurs passifs ont été mis en oeuvre: DGT (pour les métaux traces) et SBSE (pour les composés organiques hydrophobes). Les molécules hydrophiles ont été recherchées directement dans l'eau prélevée. Les mesures DGT montrent que le site de l'estuaire de Kourou se caractérise, pour tous les métaux, par des concentrations plus importantes que celles déterminées dans les deux autres stations. S'agissant de mesures ponctuelles, réalisées...

Réalisation d'un modèle de dispersion d'un rejet de dragage et des contaminants associés. Rapport définitif: contrat « LITEAU » 2ème phase ArchiMer
Alzieu, Claude; Andral, Bruno; Bassoullet, Philippe; Boutier, Bernard; Gonzalez, Jean-louis; Huet, Martial; Jestin, Herve; L'Yavanc, Jacky; Michel, Pierre; Paulet, Yves-marie; Quiniou, Francoise; Silva Jacinto, Ricardo.
Le projet à pour but de modéliser la dispersion des immersions des boues de dragage, à partir de modèles numériques de manière à pouvoir évaluer le devenir de la charge particulaire et des contaminants associés. Les résultats des expérimentations en laboratoire montrent, qu'à l'échelle représentative du temps de séjour des particules dans la colonne d'eau du champ proche (quelques heures), on ne constate pas de solubilisation des métaux. La libération de la fraction associée aux eaux interstitielles et les flux à l'interface eau-sédiment (diagenèse précoce) après dépôt des sédiments rejetés, sont les processus qui pourraient être la cause d'un apport important de Cd (ou autre contaminant) dissous dans le milieu. Les hypothèses retenues pour l'élaboration...

Caractérisation de l'état de référence biologique des masses d'eau côtières au regard de la directive cadre sur l'eau ArchiMer
Andral, Bruno; Gonzalez, Jean-louis; Cuet, Pascale; Bigot, Lionel; Turquet, Jean; Nicet, Jean Benoit.
Les travaux réalisés ont permis d’obtenir des informations pertinentes pour accompagner le programme lié à la mise en œuvre de la DCE en milieu marin, notamment le volet lié à la surveillance du compartiment biologique. Les résultats ont confirmé que la zone récifale devait faire l’objet d’une approche spécifique, compte tenu de la particularité de cet écosystème soumis à des apports en pesticides et surtout en nitrates d’origine aquifère. Des indicateurs permettent de suivre ce type de pression notamment le δ15N et le rapport C:N dans des espèces algales devraient être rapidement opérationnels. Les pressions exercées sur le corail peuvent être également suivies grâce notamment à des méthodes d’investigations réalisées sur certaines espèces comme les...

Growth, condition and metal concentration in juveniles of two Diplodus species in ports ArchiMer
Bouchoucha, Marc; Brach-papa, Christophe; Gonzalez, Jean-louis; Lenfant, P.; Darnaude, A. M..
High abundances of juvenile fish in certain ports suggest they might provide alternative nursery habitats for several species. To further investigate this possibility, post-settlement growth, metal uptake and body condition were estimated in 127 juveniles of two seabream species, collected in 2014–15, inside and outside the highly polluted ports of the Bay of Toulon. This showed that differences in local pollution levels (here in Hg, Cu, Pb and Zn) are not consistently mirrored within fish flesh. Muscle metal concentrations, below sanitary thresholds for both species, were higher in ports for Cu, Pb and V only. Otherwise, fish muscle composition principally differed by species or by year. Juvenile growth and condition were equivalent at all sites. Higher...

Metal measurement in aquatic environments by passive sampling methods: Lessons learning from an in situ intercomparison exercise ArchiMer
Dabrin, A.; Ghestem, J. -p.; Uher, E.; Gonzalez, Jean-louis; Allan, I. J.; Schintu, M.; Montero, N.; Balaam, J.; Peinerud, E.; Miege, C.; Coquery, M..
Passive sampling devices (PS) are widely used for pollutant monitoring in water, but estimation of measurement uncertainties by PS has seldom been undertaken. The aim of this work was to identify key parameters governing PS measurements of metals and their dispersion. We report the results of an in situ intercomparison exercise on diffusive gradient in thin films (DGT) in surface waters. Interlaboratory uncertainties of time-weighted average (TWA) concentrations were satisfactory (from 28% to 112%) given the number of participating laboratories (10) and ultra-trace metal concentrations involved. Data dispersion of TWA concentrations was mainly explained by uncertainties generated during DGT handling and analytical procedure steps. We highlight that DGT...

In situ kinetics of mercury bioaccumulation in mytilus galloprovincialis estimated by transplantation experiments ArchiMer
Casas, Stellio; Cossa, Daniel; Gonzalez, Jean-louis; Bacher, Cedric; Andral, Bruno.
Monitoring coastal contamination by trace metals pollution using mollusks bivalves as quantitative bioindicators is widely performed in many international biomonitoring programs. For this purpose, studying mercury dynamic in marine mussels is a reliable tool. In situ experiments on uptake and elimination kinetics were conducted in three Mediterranean sites, chosen on the basis of their contamination levels. Mussels were transplanted from a clean area to a highly contaminated one and then transferred back to a clean site. This approach makes it possible to define bioaccumulation factors and uptake and elimination rates consistently with the real environmental conditions.

Diatom artificial medium (DAM) a new artificial medium for the diatom Haslea ostrearia and other marine microalgae ArchiMer
Gagneux Moreaux, Sindy; Moreau, Christophe; Gonzalez, Jean-louis; Cosson, Richard P..
Artificial media are used in physiological studies of microalgae to maintain consistent conditions from one experiment to another and these media must be adapted to the needs of the organism studied. The artificial medium, in this case named diatom artificial medium (DAM), was designed to maintain long-term cultures of Haslea ostrearia and 19 other planktonic microalgae, and to allow physiological studies related to metal metabolism. The biomass and biochemical composition of H. ostrearia grown in the DAM and in a modified Provasoli medium were compared to assess the suitability of this new artificial medium for the culture of this diatom. The DAM provided sufficient nutrients to allow H. ostrearia to grow as efficiently as in the enriched seawater medium,...

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...

Contribution of modeling to the knowledge of trace elements behaviour and speciation in estuaries ArchiMer
Gonzalez, Jean-louis; Dange, Catherine; Thouvenin, Benedicte.
Geochemical models are excellent tools for the understanding of trace elements dynamics, in particular in complex environments like estuaries. Their aim is to reproduce numerically the biogeochemical processes observed in the field or laboratory. The development and the use of this kind of tool requires: - in-situ data on the distribution in space and time of the elements studied and relationship with the environmental variables. - experimental data (mainly based on the use of radioactive analogues of the studied elements) for evaluation of model parameters and the validation of model assumptions. The model must be capable not only of reproducing the distribution of metals between the dissolved and particulate phases, but also of evaluating the...

Assessing variability in the ratio of metal concentrations measured by DGT-type passive samplers and spot sampling in European seawaters ArchiMer
Rodríguez, Jose German; Amouroux, Isabelle; Belzunce-segarra, María Jesús; Bersuder, Philippe; Bolam, Thi; Caetano, Miguel; Carvalho, Inês; Correia Dos Santos, Margarida; Fones, Gary R.; Gonzalez, Jean-louis; Guesdon, Stephane; Larreta, Joana; Marras, Barbara; Mchugh, Brendan; Menet-nédélec, Florence; Menchaca, Iratxe; Gabet, Vanessa Millán; Montero, Natalia; Nolan, Martin; Regan, Fiona; Robinson, Craig D.; Rosa, Nuno; Sanz, Marta Rodrigo; Schintu, Marco; White, Blánaid; Zhang, Hao.
The current study evaluates the effect of seawater physico-chemical characteristics on the relationship between the concentration of metals measured by Diffusive Gradients in Thin films (DGT) passive samplers (i.e., DGT-labile concentration) and the concentrations measured in discrete water samples. Accordingly, Inductively Coupled Plasma Mass Spectrometry (ICP-MS) was used to measure the total dissolved metal concentrations in the discrete water samples and the labile metal concentrations obtained by DGT samplers; additionally, lead and cadmium conditional labile fractions were determined by Anodic Stripping Voltammetry (ASV) and total dissolved nickel was measured by Cathodic Stripping Voltammetry (CSV). It can be concluded that, in general, the median...
