Additionally, it may be found as different species in several matrices and therefore it is one of the target elements in chemical speciation. Although the number of studies in terrestrial plants is low, compared to matrices such as fish or urine, this number is raising due to the fact that this type of matrix are closely related to the human food chain. In speciation analysis, sample preparation is a critical step and several extraction procedures present drawbacks. In this review, papers dealing with extraction procedures, analytical methods, and studies of species conservation in plants cultivated in terrestrial environment are critically discussed. Analytical procedures based on extractions using water or diluted acid solutions associated with HPLC?ICP?MS are good alternatives, owing to their versatility and sensitivity, even though less expensive strategies are shown as feasible choices.  aanalytical methods  aArsenic speciation  aSample preparation  aSpecies stability  aTerrestrial plant1 aNÓBREGA, J.
