Determination of complexation of iron(III) with natural organic complexing ligands in seawater using cathodic stripping voltammetry
TL;DR: In this article, a method is presented to determine the extent of iron complexation by natural organic ligands in seawater using Catalytic cathodic stripping voltammetry (CSV) to take advantage of ligand competition between the added ligand, 1-nitroso-2-napthol (NN), and natural ligands present in seawaters.

Trace elements in the oceans
TL;DR: Trace elements are present in sea water at concentrations that range down to picomoles per litre (pmol 1-1) and even lower as discussed by the authors, and it is only recently that these have been fully overcome.
Book ChapterDOI
Heavy Metals, Major Metals, Trace Elements
TL;DR: In this paper, the authors discuss the problem of water contamination and the risks to human health as well as the economical damages it produces, and highlight the importance of human health and the need to pay attention to water contamination.

Zinc and cadmium speciation in subantarctic waters east of New Zealand
TL;DR: In this paper, the authors measured zinc and cadmium complexation by natural organic ligands in subantarctic waters east of New Zealand for four separate cruises and found that the zinc complexing ligand is truly dissolved and not associated with colloidal organic matter.
Journal ArticleDOI
Toxicity of copper complexes to the marine diatom Nitzschia closterium
TL;DR: The toxicity of many redox-active compounds and their copper complexes appears to be due, at least partly, to the intracellular generation of hydrogen peroxide during oxidation of these compounds, an effect exacerbated by the ability of copper to inhibit catalase.

Chemical speciation of chromium in sea water
TL;DR: The effect of naturally occurring organic materials on the coprecipitation behavior of trivalent chromium was studied to estimate the relative abundance of organic-bound chromium in sea water as mentioned in this paper.
Journal ArticleDOI
Dissolved state of chromium in seawater
TL;DR: In this article, the authors studied the coprecipitation behavior of chromium with ferric hydroxide and other metal hydroxides in the presence of naturally existing inorganic and organic ions to attain an accurate analytical method for determining chromium content, as well as to estimate its behaviour in natural waters.

Chemical speciation of chromium in sea water: Part 3. The determination of chromium species
TL;DR: In this paper, a method for the determination of chromium(III), chromium (VI) and organically bound chromium in sea water is reported, and it is confirmed that sea water contains about 9 × 10-9 M dissolved chromium.
