“…There was no detectable variation in TDS in river water samples collected up-and downstream between the dry (187197 mg l 1 ) and wet (160164 mg l 1 ) periods. The Allier river values are the same as those given in Négrel et al (1997aNégrel et al ( , 2003.…”

“…3). This indicates a common origin and implies that Sr content is influenced by agricultural practises by spreading of fertilisers (Négrel and Deschamps (1996) and Négrel (1999 (Négrel et al, 1997a(Négrel et al, , b, 2003.

“…Although they have been used as an atmospheric-input reference in many unpolluted hydrosystems (Meybeck, 1983;Négrel, 1999), they can also come from a variety of human activities and are found in domestic sewage, fertilisers, de-icing salts, etc. Figure 3 shows data collected from the Allier river 50 km upstream (Négrel et al, 1997a) during low water stage throughout a complete hydrological cycle, and from the Allier river 70 km downstream . Rainfall input is also plotted and represents the mean weighted concentration of 13 samples of rainwater (970 mm) collected over a oneyear period in the Massif Central (Négrel and Roy, 1998), with one sample representing all of the rainwater that fell during a one-month period, multiplied by the concentration factor of four.…”

“…By characterising three different sites in the Loire-Allier valleys within the Bourbonnais-Quaternary alluvium, the Sr isotopes in both surface and groundwater can be synthesised.

This study presents strontium isotope and major ion data of shallow groundwater and river water from the Ile du Chambon catchment, located on the Allier river in the Massif Central (France). There are large variations in the major-element contents in the surface-and groundwater. Plotting of Na vs. Cl contents and Ca, Mg, NO 3 , K, SO 4 , HCO 3 , Sr concentrations reflect waterrock interaction (carbonate dissolution for Ca, Mg, HCO 3 and Sr because the bedrock contains marly limestones), agricultural input (farming and fertilising) and sewage effluents (for NO 3 , K, SO 4 ), although some water samples are unpolluted. Sr contents and isotope ratios ( 87 Sr/ 86 Sr vary from 0.70892 to 0.71180 along the hydrological cycle) in the groundwater agree with previous work on groundwater in alluvial aquifers in the Loire catchment. The data plot along three directions in a 87 Sr/ 86 Sr vs. 1/Sr diagram as a result of mixing, involving at least three geochemical signaturesAllier river water, and two distinct signatures that might be related to different water-rock interactions in the catchment. Mixing proportions are calculated and discussed. The alluvial aquifer of the Ile du Chambon catchment is considered, within the Sr isotope systematic, in a larger scheme that includes several alluvial aquifers of the Loire Allier catchment.

This study investigates the spatiotemporal variability of major and trace elements, dissolved organic carbon (DOC), total dissolved solids (TDS), and suspended particulate matter (SPM) in surface waters of several hydrosystems of the Loire River watershed in France. In particular, this study aims to delineate the impact of the abovementioned water physicochemical parameters on natural iron and manganese physical speciation (homoaggregation/heteroaggregation) among fine colloidal and dissolved (< 10 nm), colloidal (10-450 nm) and particulate (> 450 nm) phases in Loire River watershed. Results show that the chemistry of the Loire River watershed is controlled by two end members: magmatic and metamorphic petrographic context on the upper part of the watershed; and sedimentary rocks for the middle and low part of the Loire. The percentage of particulate Fe and Mn increased downstream concurrent with the increase in SPM and major cations concentration, whereas the percentage of colloidal Fe and Mn decreased downstream. Transmission electron microscopy analyses of the colloidal and particulate fractions (from the non-filtered water sample) revealed that heteroaggregation of Fe and Mn rich natural nanoparticles and natural organic matter to the particulate phase is the dominant mechanism. The heteroaggregation controls the partitioning of Fe and Mn in the different fractions, potentially due to the increase in the ionic strength, and divalent cations concentration downstream, and SPM concentration. These findings imply that SPM concentration plays an important role in controlling the fate and behavior of Fe and Mn in various sized fractions. Graphical abstract Physical speciation by heteroaggregation of (Fe-Mn) compounds: high [SPM] → [Fe-Mn] particulate faction; low {SPM] → [Fe-Mn] colloid-dissolved fraction.
