Thibaud, Yves - 1975Le présent mémoire expose la technique d'analyse qui est utilisée actuellement à l'I.S.T.P.M. pour effectuer des dosages de mercure dans les échantillons d'origine marine, qu'ils soient constitués d'eau de mer, de coquillages ou de poissons. Cette technique nous permet, d...Contributeur (s):

Alzieu, Claude / Michel, Pierre / Thibaud, Yves - 1976A survey about mercury, chlorinated and total hydrocarbons contents in five species of coastal shellfishes shows that harbour and estuarine areas are among the most polluted. These contents are lowest for gasteropods than bivalves. For mercury and total hydrocarbons, we show there is a level,...Contributeur (s):

Thibaud, Yves - 1971Récemment la presse a largement fait écho à des empoisonnements dus au mercure. Les premiers cas sont apparus au Japon, à Minamata en 1953. D'autres suivirent à Niigata en 1965. Les malades, appartenant le plus souvent à des familles de pêcheurs, étaient atteints d'importants troubles...Contributeur (s):

Thibaud, Yves - 1973Our results show that the contamination of the French coasts by mercury is quite low, and that if there is a greater contamination, it is extremely localized. In this way, in the roadsted of Toulon, where numerous samplings have been conducted, cultivated mussels are barely contaminated whereas...Contributeur (s):

Experiments in oyster-breeding areas where oyster Crassostrea gigas suffers from anomalies of calcification, show an obvious correlation between the importance of the malformation of shells and the vicinity of port areas where a great number of boats usually stay. Organotin compounds contained in...Contributeur (s):

Thibaud, Yves - 1980The author presents an analysis technique permitting the determination of the tin in the tissues of marine organisms. This technique is only the application of the spectrophotometry of atomic absorption with atomization in the electrothermic oven. After the acid attack of the sample, the solution...Contributeur (s):

Alzieu, Claude / Thibaud, Yves / Heral, Maurice / Boutier, Bernard - 1980The boats cruising in the oyster growing areas are protected against biofouling by paints which release toxic compounds such as copper oxide and organotins into the water. After an estimation of the inputs of copper and organotins in the "Marennes-Oleron", Arcachon (Atlantic) and Thau...Contributeur (s):

Andersen, C / Thibaud, Yves / Alzieu, Claude - 1984At the various intermolt stages (A, B, C, D) the cephalothorax, abdominal muscle, exoskeleton and legs of shrimp Crangon crangon L.from the Seine Bay estuary have been analyzed for Hg, Cd, Cu, Fe and Zn. A statistical test of the results of the metal analyses, and the variations of the...Contributeur (s):
