Arsenic exists in the form of various chemical species differing by their
physicochemical behavior, in toxicity, bioavailability and biotransformation.
The determination of arsenic species is an important issue for environmental,
clinical and food chemistry. However, differentiation of these species is a
quite complex analytical task. Numerous speciation procedures have been
studied that include electrochemical, chromatographic, spectrometric and
hyphenated techniques. This review comprehends the relevant research in the
field of arsenic speciation analysis with novel applications and significant
advances. Stability of arsenic species and each of the analytical steps
(sample collection, storage, preservation, extraction) of the arsenic
speciation methods was particularly evaluated. Analytical validation and
performance of these methods are also reviewed.
