Description and Uses
Elemental mercury, a silver-white metal, is also known ‘quicksilver’ or ‘hydrargyrum.’ Mercury has been discovered in Egyptian tombs dating as far back as 1500 BC. The chemical symbol, Hg, is derived from the Greek word hydrargyros, meaning ‘water silver.’ Mercury was known in antiquity and used by alchemists. Its neurological effects were recognized early, and its use in the hat-making trade gave rise to the phrase ‘mad as a hatter.’ Mercury has been used commercially and medically for centuries. In the past it was a common constituent of many medications, for example, it was used in the treatment of syphilis. Use of mercury has been drastically reduced in recent years. Within the twentieth century, mercury used to be in every physician’s or pharmacist’s armamentarium, for example, calomel was commonly used in infant teething powders in the 1930s and 1940s.
