The Congo (Zaire) River, the world's second largest river in terms both of water discharges and drainage area after Amazon has remained to date a near‐pristine state. For period between 2 6 years, mainstream near mouth (Brazzaville/Kinshasa station) some major minor tributaries (the Oubangui, Mpoko, Ngoko‐Sangha) were monitored every month for total suspended sediment (TSS), particulate organic carbon (POC), dissolved (DOC). In this large but relatively flat equatorial basin, TSS levels are...
Since 1945, a large amount of heterogeneous data has been acquired to survey river sediment quality, especially concerning regulatory metals such as Cd, Cr, Cu, Hg, Ni, Pb, and Zn. Large-scale syntheses are critical assess the effectiveness public regulations resiliency systems. Accordingly, this synthesis proposes first attempt decipher spatio-temporal trends metal contamination along seven major continental rivers in Western Europe (France, Belgium, Germany, Netherlands). A dataset...
Abstract Water draining from a large agricultural catchment of 1 110 km 2 in southwest France was sampled over an 18‐month period to determine the temporal variability suspended sediment (SS) and dissolved (DOC) particulate organic carbon (POC) transport during flood events, with quantification fluxes controlling factors, analyze relationships between discharge SS, DOC POC. A total 15 events were analyzed, providing extensive data on POC floods. There high different seasonal floods, SS...
This study focuses on the foraminiferal distribution intertidal mudflats of two contrasted estuaries (Auray and Vie) along French Atlantic coast. In both estuaries, communities are dominated by Haynesina germanica Ammonia tepida group. Stations located near outlets show a high diversity abundance species genus Elphidium. in inner estuary higher proportion agglutinated (Ammotium salsum, Ammobaculites agglutinans). Multivariate statistical analysis suggests that distance to sea percentage fine...
Marine ecosystems are exposed to a multitude of stresses, including emerging metals as Rare Earth Elements. The management these contaminants represents significant environmental issue. For the past three decades, increasing medical use gadolinium-based contrast agents (GBCAs) has contributed their widespread dispersion in hydrosystems, raising concerns for ocean conservation. In order control GBCA contamination pathways, better understanding cycle elements is needed, based on reliable...
In European rivers, research and monitoring programmes have targeted metal pollution from bed floodplain sediments since the mid-20th century by using various sampling analysis protocols. We propose to characterise contamination trajectories 1960s based on joint use of a large amount data dated cores subsurface along Rhône River (ca. 512 km, Switzerland–France). For reconstruction spatio-temporal trends, enrichment factors (EF) geo-accumulation (Igeo) approaches were compared. The latter...
