In the United States, the Environmental Protection Agency is charged with regulating and managing mercury contamination. Several laws give the EPA this authority, including the Clean Air Act, the Clean Water Act, the Resource Conservation and Recovery Act, and the Safe Drinking Water Act. Additionally, the Mercury-Containing and Rechargeable Battery Management Act, passed in 1996, phases out the use of mercury in batteries, and provides for the efficient and cost-effective disposal of many types of used batteries. [131] North America contributed approximately 11% of the total global anthropogenic mercury emissions in 1995. [132] Thiomersal (called Thimerosal in the United States) is an organic compound used as a preservative in vaccines, although this use is in decline. [57] Although it was widely speculated that this mercury-based preservative could cause or trigger autism in children, no evidence supports any such link. [58] Nevertheless, thiomersal has been removed from, or reduced to trace amounts in all U.S. vaccines recommended for children 6 years of age and under, with the exception of inactivated influenza vaccine. [57] Merbromin (Mercurochrome), another mercury compound, is a topical antiseptic used for minor cuts and scrapes in some countries. Today, the use of mercury in medicine has greatly declined in all respects, especially in developed countries. Liquid mercury is a part of popular secondary reference electrode (called the calomel electrode) in electrochemistry as an alternative to the standard hydrogen electrode. The calomel electrode is used to work out the electrode potential of half cells. [67] Last, but not least, the triple point of mercury, −38.8344°C, is a fixed point used as a temperature standard for the International Temperature Scale ( ITS-90). [9]

In polarography both the dropping mercury electrode [68] and the hanging mercury drop electrode [69] use elemental mercury. This use allows a new uncontaminated electrode to be available for each measurement or each new experiment. Hopkinson, G. R.; Goodman, T. M.; Prince, S. R. (2004).

Mercury(I) chloride (also known as calomel or mercurous chloride) has been used in traditional medicine as a diuretic, topical disinfectant, and laxative. Mercury(II) chloride (also known as mercuric chloride or corrosive sublimate) was once used to treat syphilis (along with other mercury compounds), although it is so toxic that sometimes the symptoms of its toxicity were confused with those of the syphilis it was believed to treat. [54] It is also used as a disinfectant. Blue mass, a pill or syrup in which mercury is the main ingredient, was prescribed throughout the 19th century for numerous conditions including constipation, depression, child-bearing and toothaches. [55] In the early 20th century, mercury was administered to children yearly as a laxative and dewormer, and it was used in teething powders for infants. The mercury-containing organohalide merbromin (sometimes sold as Mercurochrome) is still widely used but has been banned in some countries such as the U.S. [56] ContemporaryHg with a half-life of 46.612 days. Most of the remaining radioisotopes have half-lives that are less than a day. 199 n 1] تم تركيب العناصر 99 إلى 118 فقط في المختبرات أو المفاعلات النووية.

HG can be extremely debilitating and cause fatigue that lasts for weeks or months. People with HG may not be able to work or perform their normal daily activities. Indicative of its tendency to bond to itself, mercury forms mercury polycations, which consist of linear chains of mercury centers, capped with a positive charge. One example is Hg 2+

Mercury(II) oxide, the main oxide of mercury, arises when the metal is exposed to air for long periods at elevated temperatures. It reverts to the elements upon heating near 400°C, as was demonstrated by Joseph Priestley in an early synthesis of pure oxygen. [17] Hydroxides of mercury are poorly characterized, as they are for its neighbors gold and silver.

Because of the high toxicity of mercury, both the mining of cinnabar and refining for mercury are hazardous and historic causes of mercury poisoning. [42] In China, prison labor was used by a private mining company as recently as the 1950s to develop new cinnabar mines. Thousands of prisoners were used by the Luo Xi mining company to establish new tunnels. [43] Worker health in functioning mines is at high risk. Due to the health effects of mercury exposure, industrial and commercial uses are regulated in many countries. The World Health Organization, OSHA, and NIOSH all treat mercury as an occupational hazard, and have established specific occupational exposure limits. Environmental releases and disposal of mercury are regulated in the U.S. primarily by the United States Environmental Protection Agency.

It has a freezing point of −38.83°C and a boiling point of 356.73°C, [10] [11] [12] both the lowest of any stable metal, although preliminary experiments on copernicium and flerovium have indicated that they have even lower boiling points. [13] This effect is due to lanthanide contraction and relativistic contraction reducing the radius of the outermost electrons, and thus weakening the metallic bonding in mercury. [10] Upon freezing, the volume of mercury decreases by 3.59% and its density changes from 13.69g/cm 3 when liquid to 14.184g/cm 3 when solid. The coefficient of volume expansion is 181.59 × 10 −6 at 0°C, 181.71 × 10 −6 at 20°C and 182.50 × 10 −6 at 100°C (per°C). Solid mercury is malleable and ductile and can be cut with a knife.
