Background: In French Polynesia, thyroid cancer mortality and incidence is reported to be the highest in the world. Excessive levels of non-essential trace elements (nETE) in the body are associated with several types of cancer. Objective: The present study aims to provide quantitative information on food contamination by mercury (Hg), lead (Pb), arsenic (As) and cadmium (Cd) in French Polynesia and its potential correlation with measurements performed in fingernails of Polynesians, and then to investigate the potential association between these nETE and different thyroid cancer risks. Methods: The study population included 229 interviewed cases and 373 interviewed controls We performed a descriptive analysis of Polynesian food and examined the association...

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....

Response of the pearl oyster Pinctada margaritifera to cadmium and chromium: Identification of molecular biomarkers

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,...
