Última Réseau de surveillance des polluants anthropiques dans les lagons de Polynésie française. Rapport final - Septembre 2014. Contrat de projet Etat-Pays ArchiMer Bernagout, Solene; Bouisset, Patrick; Leclerc, Gael; Rua, Jean; Nohl, Marine; Garen, Pierre; Levy, Peva; Tetaura, Nono-lewis; Poroi, Destremeau; Sham Koua, Manaarii; Liao, Vetea; Bosserelle, Pauline; Planes, Serge; Espiau, Benoit. La mise en place d’un réseau d’observation de la qualité des eaux lagonaires de Polynésie française, financé par le contrat de projet Etat – Pays, a été initiée mi 2012 pour une durée de deux ans. Durant un à trois semestres la contamination in situ a été suivie sur 6 sites : Vairao et la baie de Phaéton à Tahiti, Moorea (Vaiare), Huahine (Faie), Maupiti et Rangiroa. Le mollusque bioindicateur utilisé est l’huître perlière Pinctada margaritifera. Après transplantation et 4 mois d’immersion sur site, la mesure dans les chairs de la radioactivité gamma n’a pas permis de détecter de radionucléides artificiels, cependant du césium 137 a été mesuré dans les sédiments sur 2 sites. Le plutonium (émetteur alpha) est présent en faibles quantités dans les chairs....

This study was designed to identify in the pearl oyster Pinctada margaritifera, used as a bio-accumulator, molecular biomarkers for the presence of heavy metals in the lagoon environment. Pearl oysters were exposed to 2 concentrations (1 and 10 μg L− 1) of cadmium (Cd) and chromium (Cr) compared to a control. Twelve target genes encoding proteins potentially involved in the response to heavy metal contamination with antioxidant, detoxification or apoptosis activities were selected. P. margaritifera accumulated Cd but not Cr, and mortality was related to the amount of Cd accumulated in tissues. In response to Cd-Cr contamination, metallothionein (MT) was significantly up-regulated by Cd-Cr at both concentrations, while 7 others (SOD, CAT, GPX, GSTO, GSTM,...

Ano: 2017 URL: http://archimer.ifremer.fr/doc/00376/48707/49146.pdf Speciation of dissolved copper within an active hydrothermal edifice on the Lucky Strike vent field (MAR, 37 degrees N) ArchiMer Sarradin, Pierre-marie; Waeles, M; Bernagout, Solene; Le Gall, Christian; Sarrazin, Jozee; Riso, R. The objective of this study was to deter-mine the concentrations of different fractions of dissolved copper (after filtration at 0.45 mu m) along the cold part of the hydrothermal fluid-seawater mixing zone on the Tour Eiffel edifice (MAR). Dissolved copper was analyzed by stripping chronopotentiometry (SCP) after chromatographic C-18 extraction. Levels of total dissolved copper (0.03 to 5.15 mu M) are much higher than those reported for deep-sea oceanic waters but in accordance with data previously obtained in this area. Speciation measurements show that the hydrophobic organic fraction (C18Cu) is very low (2 +/- 1%). Dissolved copper is present mainly as inorganic and hydrophilic organic complexes (nonC(18)CU). The distribution of copper along the pH... Tipo: Text Palavras-chave: Mid Atlantic Ridge; Hydrothermal vent; Speciation; Dissolved copper.
