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:

Sources, Mobility and Bioavailability of Trace Metals and Metalloids in the Historically Mining and Smelter Impacted Altiplanean City of Oruro, Bolivia
Tapia Zamora,Joseline Soledad +1 more
TL;DR: A collection of 91 sediment samples retrieved from ve sedimentary cores from Lake Uru Uru (Altiplano) and Cala Cala Lagoon (Eastern Cordillera) subjected to a total digestion technique, plus a compilation of preexistent data base of trace element concentration in soil and lacustrine sediment obtained from the Oruro Pilot Project (PPO) allowed to propose a geochemical background and a present-time baseline for As, Cd, Cu, Pb, Sb and Zn in sediments from this area as mentioned in this paper.

Creating metal-spiked bed sediments: a case study from Orewa estuary, New Zealand.
TL;DR: A method has been developed to create Cu-, Pb-, and Zn-spiked sediments in which naturally occurring adsorption onto sediment surfaces is the dominant process binding the metals and in which precipitation of readily redissolved minerals and other metal-bearing phases (artifacts of the spiking procedure) are avoided.

Distributions of trace metals Co, Cu and Cd in northern Sagami Bay, Japan and their relationship to estuarine variables
TL;DR: In this article, the trace metals Co, Cu and Cd in surface waters were determined to test whether DOC, which is an indicator of dissolved organic matter (DOM), and organic matter in suspended particulate matter (SPM) act as important estuarine variables controlling the distributions of these metals in the estuarial zone.

Procedimentos de fracionamento comparados a modelo de atenuação para a avaliação de mobilidade de metais pesados em sedimentos da Baía de Sepetiba, Rio de Janeiro
TL;DR: In this article, the acid-volatile sulfides (AVS) and the concentration of simultaneously extracted metals (SEM) were determined in 65 sediment samples from Sepetiba bay, representing the whole area, with high concentrations in the northeastern region of the bay, classifying the area as level 2, for Zn, and as level 1, for Cd, Cu, and Ni.

Flocculation of dissolved organic and inorganic matter during the mixing of river water and seawater
TL;DR: In this paper, a new approach to estuarine studies is presented which establishes 1) the extent and salinity dependence of non-conservative behaviour; 2) composition and chemical form of removal products; and 3) abiological removal mechanisms.

The mechanism of iron removal in estuaries
TL;DR: A survey of U.S. east coast estuaries confirms that large-scale rapid removal of iron from river water is a general phenomenon during estuarine mixing as discussed by the authors.

Copper complexation in the Northeast Pacific
TL;DR: Copper titrations were conducted at sea with differential pulse anodic stripping voltammetry to examine the degree to which copper was associated with organic ligands as discussed by the authors, finding that approximately 50-70% of the total dissolved copper was in the organically complexed form.

Complexation of zinc by natural organic ligands in the central North Pacific
TL;DR: In this paper, the complexation of Cd by natural organic ligands in the upper 600 m of the central North Pacific was determined with differential pulse anodic stripping voltametry at a thin mercury film, rotating glassy-carbon disk electrode.
