All humans are exposed to some degree of mercury. Human exposure happens mostly through inhalation of elemental mercury vapours all through industrial processes and through usage of contaminated fish and shellfish.
Mercury happens as salts including mercuric chloride (HgCl2) and mercurous chloride (Hg2Cl2), the latter often called calomel. Given that they are more soluble in water, mercuric salts are usually a lot more acutely toxic than mercurous salts. Their bigger solubility allows them be far more quickly absorbed from the gastrointestinal tract. Mercury salts have an impact on mainly the gastrointestinal tract and the kidneys, and could cause extreme kidney destruction; on the other hand, as they can't cross the blood–Mind barrier conveniently, these salts inflict small neurological harm without the need of continuous or hefty exposure.

Gaseous mercury is used in mercury-vapor lamps and many "neon indication" kind marketing signs and fluorescent lamps. Those people very low-strain lamps emit really spectrally slim lines, which might be traditionally used in optical spectroscopy for calibration of spectral placement. Industrial calibration lamps are bought for this intent; reflecting a fluorescent ceiling gentle right into a spectrometer is a standard calibration observe.[95] Gaseous mercury is usually found in a few electron tubes, including ignitrons, thyratrons, and mercury arc rectifiers.
