The key way that folks are subjected to mercury is by consuming fish and shellfish that have significant levels of methylmercury, a very toxic kind of mercury, within their tissues. A significantly less typical way individuals are subjected to mercury is breathing mercury vapor.
Numerous Chinese emperors along with other Chinese nobles are identified or suspected to own died or been sickened by mercury poisoning soon after alchemists administered them "elixirs" to advertise wellness, longevity, or immortality that contained possibly elemental mercury or (more commonly) cinnabar.

Gaseous mercury is used in mercury-vapor lamps and several "neon indicator" style promoting indications and fluorescent lamps. Those people low-pressure lamps emit quite spectrally slim traces, that happen to be historically used in optical spectroscopy for calibration of spectral posture. Business calibration lamps are marketed for this goal; reflecting a fluorescent ceiling mild into a spectrometer is a standard calibration exercise.[ninety five] Gaseous mercury is usually found in certain electron tubes, together with ignitrons, thyratrons, and mercury arc rectifiers.

Ethylmercury is a breakdown product on the antibacteriological agent ethylmercurithiosalicylate, that has been used for a topical antiseptic and also a vaccine preservative (further talked over underneath Thiomersal under). Its characteristics have not been studied as extensively as People of methylmercury.
