What is Arsenic?
Arsenic is a naturally occurring element in the earth’s crust. Pure arsenic is a gray colored metal. Inorganic arsenic is found combined with other elements such as oxygen, chlorine and sulfur. The organic form of arsenic however is much less toxic than the inorganic form of this element. Most inorganic and organic arsenic compounds are white colorless powders that do not evaporate. They have no smell, and most have no taste. Thus, is usually difficult tell if arsenic is present in foods, water, or in the air.
