Origin, retention and release of trace metals from sediments of the river seine

Historical perspective of heavy metals contamination (Cd, Cr, Cu, Hg, Pb, Zn) in the Seine River basin (France) following a DPSIR approach (1950–2005)

“…Baize (1997); (g) Alzieu (1999). (a) in Noppe (1996); (b) SEQ-Eau (1996); (c) de Pontevès et al (2005) Cd, Cr, Cu, Pb and Zn, Bonté et al (in prep) in floodplain cores; (b) Hg in SPM, Chesterikoff et al (1973) ; (c) Ni : in estuarine sediments, Avoine et al (1986); (Garban et al, 1996); (i) in a core at Chatou . …”

“…As a result, several scientific teams were clustered into the Piren-Seine multidisciplinary programme in 1989, funded by a dozen of public and private institutions of the Seine Basin and backed by the AESN. The Piren-Seine scientists developed a second stage of metal surveys in the catchment on sediments and biota Chevreuil et al, 1995 and1996;Garban et al, 1996) flood deposits (Idlafkih et al, 1995;Idlafkih, 1998;Horowitz et al, 1999), urban runoff (Estèbe et al, 1998), atmospheric fallout (Azimi et al, 2003) and, since 2004, on floodplain cores (Bonté et al, in preparation). In parallel, numerous studies on the metal distribution in the Seine estuary were realized within the SeineAval programme (Cossa and Ficht 1999;Chiffoleau et al 1999, Cossa et al 2002.…”

Zn isotopes in the suspended load of the Seine River, France: Isotopic variations and source determination

“…At lower water stage, a decrease in nitrate, Ca and HCO 3 concentrations can be attributed to the increased activity of riverine biomass (phytoplankton and chlorophytes), and to the associated precipitation of carbonate and Fe oxides (Garban et al, 1996;Meybeck et al, 1998;Roy et al, 1999;Thevenot et al, 2007;Cloquet et al, 2008). Since organic matter and oxides have strong affinities for metals (Pokrovsky and Schott, 2002), these precipitates would incorporate Zn and thus lead to higher Zn concentrations in the SPM.…”

Pb-binding to various dissolved organic matter in urban aquatic systems: Key role of the most hydrophilic fraction

“…In a recent study, spatio-temporal changes in the concentrations of dissolved Pb in an urban stream were strongly related to quantity and quality of DOM (Park, 2009). In addition to controlling dissolved lead speciation, dissolved organic matter could also be responsible for the release of Pb and other metals from the sediment to the water column, as it has been already observed downstream of Paris (Garban et al, 1996). Moreover, another study suggests a possible removal of trace metals from suspended particulate matter by dissolved organic matter resulting in an increase of dissolved trace metal concentration (Shafer et al, 1997).…”
