Hazardous Substances Data：

Toxicity：

Human exposure occurs occupationally and via food, tobacco smoke, ambient air, and water. Three major groups of arsenic compounds have been defined on the basis of biological considerations: inorganic arsenicals; organic arsenicals; and arsine (gas). The comparative toxicity of these groups is dependent upon the route of exposure and their solubilities; the more quickly absorbed compounds have lower LD50. Arsenic is readily absorbed by the respiratory and gastrointestinal systems and is concentrated in the skin, hair, and nails (Aldrich-Mees’ lines). The cellular toxicity of arsenic is related to reactions with SH-containing mitochondrial enzymes that result in impaired respiration. Arsenic may also compete with phosphate during oxidative phosphorylation.
