Resumen:
It is well established that chronic exposure to arsenic can cause cancerous and non-cancerous health hazards. However, epidemiological and experimental evidence suggest that the development of arsenic-related diseases is not only determined by the dosage of exposure, but also by its chemical form. It is generally accepted that the +3 methylated arsenic species are more cyto- and genotoxic, and more potent enzyme inhibitors than both their pentavalent counterparts and the inorganic arsenic species \cite{1}. In this regard, becomes necessary to know chemical species of accumulated arsenic in target organs in order to do more efficient therapy strategies.
