PHONETICS

Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is a pure form of mercuric sulfide, mostly obtained by the reaction with mercury, cinnabar and sulfur. Poisoning can result from exposure to water-soluble forms of mercury (mercuric chloride or methylmercury), inhalation of mercury vapour, or eating seafood contaminated with mercury.

ELEMENT BRIEF

Circa 5,000 BCE by the Egyptians.

DISCOVERY
