“…Mientras el As elemental es muy poco tóxico por su escasa solubilidad, el arseniuro de hidrógeno o arsina, gas incoloro con fuerte olor aliáceo, 2´7 veces más pesado que el aire, algo soluble en agua, pero insoluble en éter y alcohol [1] que se forma por la reacción de hidrógeno con As y se genera como un subproducto en el refinamiento de metales no ferrosos [13], provoca hemólisis rápida y severa [13]. La presentación de los efectos debido a una exposición a este gas incluyen un periodo de latencia de 24 horas [7].…”

Arsenic (As) was isolated for the first time as a chemical element by Jabir-Ibn-Haiyanb in the year 776, and its name comes etymologically from the Greek arsenicon (masculine). It is gray in color and of a shining metallic appearance, has little metallic properties, is distributed widely in the universe and its toxicity depends on the different chemical forms and states of oxidation that it has:-3, 0, +3 and +5. The historical evolution of the toxicology is intimately united to the use of this nonmetal. At present, arsenical substances are used in industry, agriculture, cattle ranching, and medicine. For that reason, the sources of exposure of man to this metal are diverse; out standing are labor, food and medicaments. In this work a revision is made of the etiology, preventive measures, analysis, diagnosis and treatment of the poisoning by As.
