Cet article présente les résultats d'une recherche pluridisciplinaire (géochimie, sociologie) portant sur l'accroissement observé des concentrations d'argent sous la forme particulaire et nanoparticulaire (Ag et nanoAg) dans les milieux aquatiques de l'estuaire de la Gironde. Il propose conjointement d'analyser les risques d'une contamination des m...
In order to understand the impact of hydrological changes of the Amazon River on sedimentary organic matter (OM) composition in Amazonian floodplain lakes, three sediment cores were collected from Lake Maraca (eastern Amazonia) along a transect from the Amazon River main channel to inland. The cores were dated with C-14 accelerator mass spectrometr...
