Arsenic As 33 74.9216

Albertus Magnus of Germany isolated arsenic in the 13th century, but it was not identified as an element until 1649, by J. Schroeder. Most arsenic is found in poisons manufactured for the control of boll weevils, leaf rot, or insect pests on livestock. Despite its widespread use, it can slowly accumulate in the body until it reaches toxic levels. Most cases of arsenic poisoning result from ingestion of house and garden pesticides.
