![]() ![]() It forms readily when elemental metallic arsenic is heated to high temperatures or burned. The physical and chemical properties of arsenic trioxide are presented in this Medical Management Guideline the guidelines for decontamination and medical treatment are applicable for exposure to arsenic and inorganic arsenic compounds, including arsenic trioxide.Īrsenic trioxide is a white or transparent solid in the form of glassy, shapeless lumps or a crystalline powder that resembles sugar. Physical and chemical properties vary among the various arsenic compounds of toxicological concern. Other inorganic arsenic compounds may vary somewhat in relative toxicity, and organic arsenic compounds appear to be essentially nontoxic. This Medical Management Guideline focuses on arsenic trioxide (As 2O 3), one of the most toxic and prevalent forms. The toxicity of a particular arsenic compound depends in part on its solubility.Īrsenic compounds exist in a number of inorganic and organic forms. Acute signs and symptoms include nausea, vomiting, diarrhea, gastrointestinal hemorrhage, cerebral edema, tachycardia, dysrhythmias, and hypovolemic shock. Arsenic trioxide is readily absorbed if ingested or inhaled, but only slowly absorbed through the skin.The water solubility of arsenic salts varies depending on the salt. Arsenic trioxide (an odorless, tasteless, white or transparent, nonflammable solid) is one of the most toxic and prevalent forms of arsenic. Elemental arsenic is usually a steel grey metal-like material without characteristic taste or smell.Persons whose clothing or skin is contaminated with arsenic may secondarily contaminate others by direct contact or through release of inhalable dust.Medical Management Guidelines for Arsenic (As) and Inorganic Arsenic Compounds
