Journal ArticleDOI
Sequential extraction procedure for the speciation of particulate trace metals
TL;DR: In this paper, an analytical procedure involving sequential chemicai extractions was developed for the partitioning of particulate trace metals (Cd, Co, Cu, Ni, Pb, Zn, Fe, and Mn) into five fractions: exchangeable, bound to carbonates, binding to Fe-Mn oxides and bound to organic matter.
Journal ArticleDOI
Metal sorption to diagenetic iron and manganese oxyhydroxides and associated organic matter: Narrowing the gap between field and laboratory measurements
TL;DR: In this paper, X-ray diffraction and electron microscopic analyses indicated that the Fe-rich material collected was predominantly ferrihydrite and poorly crystallized lepidocrocite, while the Mn-rich mixture was a mixture of poorly crystallised Mn oxyhydroxides.
Book ChapterDOI
Partitioning of trace metals in sediments: Relationships with bioavailability
TL;DR: In this article, a major fraction of the trace metals introduced into the aquatic environment is found associated with the bottom sediments, distributed among a variety of physico-chemical forms.
Journal ArticleDOI
Potential artifacts in the determination of metal partitioning in sediments by a sequential extraction procedure
TL;DR: Copper, iron, and zinc were particularly sensitive to sample pretreatment, and the maintenance of oxygen-free conditions during the extractions is of critical importance for anoxic sediments.
Journal ArticleDOI
Interactions between arsenic and iron oxyhydroxides in lacustrine sediments
Nelson Belzile,André Tessier +1 more
TL;DR: In this paper, the binding constants of As onto natural Fe oxyhydroxides have been calculated from the concentrations of As and Fe determined in leachates of surficial lake sediments and the in situ measurement of dissolved As in their respective overlying waters.
