Tributyltin along the Coasts of Corsica (Western Mediterranean): A Persistent Problem

Autor: Bernard Averty, Pierre Michel, Bruno Andral, François Galgani, Jean-Francois Chiffoleau

Publikováno v: Marine Pollution Bulletin. 42:1128-1132

Despite optimistic forecasts by various scientists after regulatory measures were taken in the 1980s, coastal tributyltin (TBT) contamination is still a major problem. The present study concerning Corsica (Western Mediterranean) shows that contaminat

High resolution profiles for arsenic in the Seine Estuary. Seasonal variations and net fluxes to the English Channel

Autor: Jean-Francois Chiffoleau, Pierre Michel, Dominique Auger, Bernard Averty, Emmanuelle Chartier

Publikováno v: Continental Shelf Research. 19:2041-2061

Three sampling cruises were conducted in the Seine Estuary from 1993 to 1995 in varying hydrological and seasonal conditions. The site included all of the lower part of the river under the influence of tidal dynamics and the dilution plume in the Bai

Distribution and Fate of Tributyltin in Surface and Deep Waters of the Northwestern Mediterranean

Autor: Pierre Michel, Bernard Averty

Publikováno v: Environmental Science & Technology. 33:2524-2528

Tributyltin (TBT) contamination of marine organisms collected in the open sea or in deep seawaters has been considered in several studies but not the contamination levels in these waters far from pollutant sources. This study conducted in June 1998 m

Contamination of French Coastal Waters by Organotin Compounds: 1997 Update

Autor: Bernard Averty, Pierre Michel

Publikováno v: Marine Pollution Bulletin. 38:268-275

Fifteen years ago, France took regulatory measures to limit the use of organotin compounds in antifouling paints for the protection of boat hulls. France was the first country to take these emergency steps, which were intended to defend the oyster-fa

Behaviour of arsenic on the continental shelf off the Gironde estuary: Role of phytoplankton in vertical fluxes during spring bloom conditions

Autor: Pierre Michel, Emanuelle Chartier, Bernard Boutier, Dominique Auger, Alain Herbland, Luis Felipe Artigas, Bernard Averty

Publikováno v: Oceanologica Acta (0399-1784) (Gauthier-villars/editions Elsevier), 1998-03, Vol. 21, N. 2, P. 325-333

The arsenic (As) cycle in the marine environment is known to be sensitive to biological activity. Within the scope of the National Coastal Oceanography Program, we undertook a specific study of the behaviour of this element in a water column on the c

Influences of bioavailability, trophic position, and growth on methylmercury in Hakes (Merluccius merluccius) from Northwestern Mediterranean and Northeastern Atlantic

Autor: Lei Chou, Capucine Mellon-Duval, Véronique Loizeau, Mireille Harmelin-Vivien, Sylvette Crochet, Daniel Cossa, Bernard Averty, J-F. Cadiou

Methylmercury (MeHg) determinations in hake, its food-chain, and the surrounding waters and sediments allowed us to show that the higher length or age normalized mercury concentrations of Northwestern Mediterranean (Gulf of Lions: GoL) muscle hakes c

Seasonal snow is an active media and an important climate factor that governs nutrient transfer in Arctic ecosystems. Since the snow stores and transforms nutrients and contaminants, it is of crucial importance to gain a better understanding of the d
