Geochemistry of trace metals in the Gironde estuary
TLDR
In this paper, the authors measured the dissolved, particulate, and (by cross-flow filtration) colloidal fractions of Cd, Ni, Zn, Cu, Pb, Mn, and Fe in the Gironde, an estuary in southwestern France.About:

Properties of fluorescent dissolved organic matter in the Gironde Estuary
Arnaud Huguet,Arnaud Huguet,Lilian Vacher,Stéphane Relexans,Sylvain Saubusse,Jean-Marie Froidefond,Edith Parlanti +6 more
TL;DR: In this paper, the authors used excitation-emission matrix (EEM) spectroscopy, a sensitive technique that allows direct analysis of water samples, to better characterize DOM in the Gironde Estuary (southwestern France).

Chemical composition of suspended sediments in World Rivers: New insights from a new database
TL;DR: A new database on the chemical composition of suspended matter in World Rivers, together with the associated elemental fluxes is presented, showing that riverine fluxes are similar to anthropogenic fluxes, which casts light on the effect of human activities on the cycles of trace elements at the Earth's surface.

The oceanic mass balance of copper and zinc isotopes, investigated by analysis of their inputs, and outputs to ferromanganese oxide sediments
TL;DR: In this paper, the authors investigated the biogeochemical cycling of copper (Cu) and zinc (Zn) isotopes in the ocean and presented estimates for the isotopic composition of the inputs to the oceans based on new data presented here and published data.

Dissolved trace metal distributions in Port Jackson estuary (Sydney Harbour), Australia.
TL;DR: Concentrations of dissolved metals were determined for summer and winter, under low-flow conditions in Port Jackson, a microtidal, well-mixed estuary in south-east Australia, and provide a data set against which the long-term contamination may be assessed.

Geochemical survey and metal bioaccumulation of three bivalve species (Crassostrea gigas, Cerastoderma edule and Ruditapes philippinarum) in the Nord Medoc salt marshes (Gironde estuary, France)
TL;DR: Results suggest trace metal recycling due to reductive dissolution under suboxic conditions at the sediment surface resulting in trace metal release to the water column and adsorption onto suspended particles.

Trace metal distribution, partition and fluxes in the Seine estuary (France) in low discharge regime
TL;DR: In this article, samples collected in surface waters of the Seine estuary (France) during a low discharge period were analyzed for dissolved and particulate trace metals (Cd, Co, Cu, Mn, Ni, Pb and Zn).

Trace metal determinations in estuarine waters by electrothermal atomic absorption spectrometry after extraction of dithiocarbamate complexes into freon
TL;DR: In this article, the dithiocarbamate complexes of the metals are extracted into Freon-TF and back-extracted into dilute nitric acid solution, which gives complete separation from the matrix irrespective of salinity.

The chemical mass balance of the amazon plume—II. Copper, nickel, and cadmium
TL;DR: In this paper, the authors show that copper and nickel are unreactive in the Amazon plume on a time scale of a few days: in both field and laboratory studies the elements are related linearly to salinity, so that neither adsorption and precipitation not desorption reactions significantly alter the net flux of these elements.

Lead cycling in estuaries, illustrated by the Gironde estuary, France
TL;DR: In the Gironde (France) as mentioned in this paper, the mixing of polluted particles with old deposits probably has a minor role in the decrease in paniculate lead. But it is not known whether this is the case in the lower Gironde estuary. And it is possible that in this lower estuary, lead-depleted particles are recycled to the tidal estuary by landward currents, where they become mixed with fresh river-borne particles.

Trace elements in the Mississippi River Delta outflow region: Behavior at high discharge
Alan M. Shiller,Edward A. Boyle +1 more
TL;DR: In this article, the authors collected surface waters of the plume of the Mississippi River during a period of high river discharge and compared these field data with results of laboratory mixing experiments, finding that Cu, Ni, and Mo are largely unreactive in the river plume.
