The elemental Arsenic may be found as the metal element or as a compound where it is combined with other elements, such as with oxygen to form arsenic trioxide. [69] See more Arsenic is one of the most ancient elements known to human history and was isolated as a distinct compound by Albertus Magnus in 1250. Where does environmental arsenic come from? 2. He heated a common compound of arsenic, As2S3, with soap and formed nearly pure arsenic. Arsenic is often found in ground water, and there are some parts of the world with drinking water that is contaminated with an unsafe level of arsenic. 8 parts per million by weight. People can also be exposed to arsenic in other ways, such as in some man-made products It was first recognized as an element by alchemists. Arsenic is found sometimes as an element in the ground, but is normally found in minerals. Elemental arsenic was first identified in 1649, but its minerals have been known since Aristotle first described them in the fourth century BC. Arsenic exhibits a wide range of properties and plays diverse roles in both ancient and modern times. It is very toxic and can enter the biological system through contaminated water, soil and air. Arsenic: Discovered in approximately 1250 by Albertus Magnus 34. ). Arsenic comes in two forms (organic and inorganic); the inorganic form is more toxic than the organic form. Crystals of elemental (native) arsenic are found in nature, although rarely. Philippia was subsequently found to be a mixture of terbium and erbium.
