Abstract: This paper presents an overview of methods for chemical
speciation analysis of elements in samples of sediments and soils. The
sequential leaching procedure is thoroughly discussed, and examples
of different applications are shown. Despite some drawbacks, the sequential
extraction method can provide a valuable tool to distinguish among trace
element fractions of different solubility related to mineralogical phases.
The understanding of the speciation of trace elements in solid samples
is still rather unsatisfactory because the appropriate techniques are
only operationally defined. The essential importance of proper sampling
protocols is highlighted, since the sampling error cannot be estimated
and corrected by standards. The Community Bureau of Reference (BCR)
protocols for sediment and soil give a good basis for most of the solid
samples, and the results can be compared among different laboratories.
