Chromium occurrence in the environment and methods of its speciation.
J. Kotaś,Z. Stasicka +1 more
TL;DR: It is demonstrated that knowledge of interconversion processes between different Cr forms is necessary to understand its behaviour and role in the environment, in addition to enabling reliable Cr speciation analysis to be performed.

Fractionation studies of trace elements in contaminated soils and sediments: a review of sequential extraction procedures
TL;DR: In this paper, the authors present a review of sequential selective extraction techniques, with their advantages and disadvantages, and discuss the limits of sequential extraction procedures for the particular case of elements giving anionic species.
Journal ArticleDOI
Heavy metal distribution in marine sediments from the southwest coast of Spain
TL;DR: It is found that Zn is the most mobile metal and showed the highest percentages in the acid-soluble fraction (the most labile), especially in the central coastal area, where the samples contained over 50% of this element associated with this fraction.
Journal ArticleDOI
Status of trace element emission in a coal combustion process: a review
TL;DR: In this paper, the occurrence of trace elements (TEs) in coal and combustion waste are introduced. And the mechanisms of trace element transformation during combustion are illustrated as following: the vaporized metals at high temperature near the combustion flame will subsequently nucleate or condense at a lower temperature downstream.
Journal ArticleDOI
Evaluation of heavy metal availability in polluted soils by two sequential extraction procedures using factor analysis.
TL;DR: Cd, Cu and Zn labile levels were related to total metal grass contents indicating its suitability for the availability studies in polluted soil-plant system, as well as between the levels of the different sequential fractions and the total content in grass.

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.

Trace metal chemistry in arid-zone field soils amended with sewage sludge: I. Fractionation of Ni, Cu, Zn, Cd, and Pb in solid phases
TL;DR: The surface horizons of two arid-zone fields soils that had received amendments of either liquid or dried, anaerobically digested sewage sludge for 4 years were sampled to determine the forms of selected trace metals in the solid phase as discussed by the authors.

Studies on soil copper i. the fractionation of copper in soils
R. G. McLAREN,D. V. Crawford +1 more
TL;DR: In this article, a method for fractionating soil copper was developed and applied to 24 soils representing a range of British soil types, and it was suggested that the concentration of copper in the soil solution is controlled by equilibria involving specifically adsorbed copper and that the bulk of the available soil copper reserves reside in the organically bound fraction.
