The spatial and temporal trends of Cd, Cu, Hg, Pb and Zn in Seine River floodplain deposits (1994–2000)

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

“…Detailed information is provided in Meybeck et al (1998) and Grosbois et al (2006). The Seine basin currently accounts for 25 % of French agriculture, 25 to 30% of French industrial activity and 23% of French population for only 12% of the French territory and less than 10% of its total water flow and sediment transport.…”

“…Metal budget determination and studies of multiple interactions between metals and Humans are fully detailed for the current period in a companion paper (Thévenot et al, this volume). Within the PIREN-Seine, previous works on metal contamination include combined sewer overflows to the river (Estèbe et al, 1998), urban fallout (Garnaud et al, 1998, Azimi et al, 2003, contamination of aquatic biota , Chevreuil et al, 1995, spatial structure of contamination (Meybeck, 1998), flood deposits contamination (Horowitz et al, 1999, Meybeck et al, 2004 and contamination trends of river particulates over the last 10 years (Grosbois et al, 2006). Other previous studies on heavy metals in the Seine River system concern the distribution of metals between dissolved and particulates phases (Idlafkih et al, 1995), the Hg contamination in the estuary (Chiffoleau et al, 1999;Cossa and Ficht, 1999;Cossa et al 2002) and Pb isotopes tracing (Roy et al, 1999).…”

Floodplain morphodynamics and distribution of trace elements in overbank deposits, Vistula River Valley Gorge near Solec nad Wisłą, Poland

“…Trace metal concentrations in the Vistula River Valley sediments of the study area are lower than in floodplain sediments of contaminated European rivers, such as: Rhine (Martin 2004), Dill (Martin 2015), Seine River (Grosbois et al 2006) or Odiel River (Santos Bermejo et al 2003).…”

Metal contamination budget at the river basin scale: an original Flux-Flow Analysis (F2A) for the Seine River

“…The non ferrous metal industries yearbooks are our main data source from the private sector (FE-DEM, 2003). For the Environmental state, academic studies (most of them generated by the PIREN Seine program, Azimi et al, 2003;Azimi et al, 2005;Garnaud et al, 1999;Gromaire et al, 2002;Grosbois et al, 2006;Meybeck et al, 2007;Thévenot et al, 2007) were used, along with river survey data at the River basin scale from the River Basin Authority and data arising from European programs (such as the Corine Land Cover from the European Environmental Agency, EEA, 2000), and some data coming from ministries.…”

“…River outputs T4, Fig. 1, Table 2) were averaged over the 1990-2000 period, to smooth the annual variation of river metal contamination (Gromaire et al, 2002;Grosbois et al, 2006;Meybeck et al, 2007), which results from the following events: (i) during major storm events Paris sewers overflow into the river, resulting in spikes of suspended matter contamination within the Parisian reach; (ii) during high water periods metal contents may vary with tributary mixing and re-suspension of deposited sediments; (iii) year to year variations of average metal contents in suspended particulate matter (SPM) are linked to the average river discharge with higher values observed during dry years; (iv) on the contrary the river fluxes of metal are directly linked to suspended matter fluxes, always higher during wet years. The sediment transport during floods is not relevant here since we are considering 5y averages based on bimonthly SPM analyses and daily suspended sediment fluxes at river mouth and/or annual flood deposits which are representative of high flow periods (Horowitz et al, 1999).…”
