Keterangan

      Arsenic is a carcinogen, associated with lung cancer when inhaled. Contact with skin can result in skin cancer. Also damage to intestines and liver. Toxic when ingested. Found in pesticides and wood preservatives. It is naturally occurring in many household products. It may have been known to ancient civilizations, but was probably first isolated by Magnus who lived between 1193-1280. Many sources reference 1250 as the year of discovery but this may be speculation.
