Publikováno v: Marine Environmental Research (0141-1136) (Elsevier BV), 2022-04, Vol. 176, P. 105594 (11p.)

Despite the effective remediation efforts following the end of the metallurgic activity thirty years ago upstream the Lot River watershed, the levels of cadmium (Cd) accumulated in wild oysters from the downstream Gironde Estuary still exceed nowaday

Despite major management efforts initiated in 1987 and 2007 and decreasing emissions in the Gironde watershed, cadmium (Cd) levels in oysters from the downstream Gironde estuary are still higher to the consumption limit (5 mg/kg, dw, EC). Dissolved C

Dispersion scenarios of radioactive antimony in a macro-tidal continent-ocean transition system

Autor: Jörg Schäfer, Lionel Dutruch, Teba Gil-Díaz, Frédérique Pougnet

Antimony (Sb) radionuclides (e.g., 125Sb half-life of 2.76 y), are fission products of nuclear reactions released to the environment during nuclear power plant (NPP) accidental events and current operating fuel reprocessing. In coastal systems, 125Sb

Tellurium behaviour in a major European fluvial–estuarine system (Gironde, France): fluxes, solid/liquid partitioning and bioaccumulation in wild oysters

Publikováno v: Environmental Chemistry (1448-2517) (CSIRO Publishing), 2019-07, Vol. 16, N. 4, P. 229-242

Environmental contextThe environmental behaviour of tellurium is poorly understood. We investigate the transport of tellurium in both dissolved and particulate forms from the river watershed to the Gironde Estuary, where a 30-year historical record p

Concentrations of inorganic tin (Sn(inorg)), tributyltin (TBT) and its degradation products dibutyltin (DBT) and monobutyltin (MBT) were measured in surface sediments and in two cores from the Toulon Bay, hosting the major French military harbour. An
