Mercury: A silver metallic element that exists as a liquid at room temperature. It has the atomic symbol Hg (from hydrargyrum, liquid silver), atomic number 80, and atomic weight 200.59. Mercury is used in many industrial applications and its salts have been employed therapeutically as purgatives, antisyphilitics, disinfectants, and astringents. It can be absorbed through the skin and mucous membranes which leads to MERCURY POISONING. Because of its toxicity, the clinical use of mercury and mercurials is diminishing.Mercury PoisoningMercury Compounds: Inorganic compounds that contain mercury as an integral part of the molecule.Mercury Poisoning, Nervous System: Neurologic disorders associated with exposure to inorganic and organic forms of MERCURY.

  • Mercury in the mother's body passes to the fetus and may accumulate there. (cdc.gov)
  • If anything, the fetus has been shown in human studies to be more susceptible to the toxic effects of mercury than are infants, because mercury easily penetrates into the fetal brain and kidneys and causes damage. (medscape.com)

  • The methylation of mercury is known to depend on the chemical forms of mercury (Hg) present in the environment and the methylating bacterial activity. (rsc.org)
  • We conducted a PubMed search in September 2014 and retrieved 14 studies on the influence of genetics on mercury toxicokinetics and ten on neurological effects of gene-mercury interactions. (springer.com)
  • Mercury" fillings (amalgam) replacement has been a controversial subject for a long time. (naturezadental.co.uk)
  • We recognise that the replacement of dental mercury fillings will not necessarily guarantee a change in the health status of patients and would strongly recommend that all medical complaints be thoroughly investigated by a relevant medical practitioner. (naturezadental.co.uk)
  • abstract = "The channel-forming activity of the lipodepsipeptide syringopeptin 25A (SP25A) was investigated at a tethered bilayer lipid membrane (tBLM) with a dioleoylphosphatidylcholine distal leaflet, anchored to a mercury electrode through a hydrophilic tetraethyleneoxy spacer.

  • abstract = "Mercury is a redox-active heavy metal that reacts with active thiols and depletes cellular antioxidants. (nebraska.edu)
  • It is investigated as an intermediate chemical species in the reduction of mercuric solutions to elemental mercury, and for its effect on high sensitivity isotope-ratio mass spectrometry methods that involve mercury, such as MC-ICP-MS, when used to compare thallium to mercury. (wikipedia.org)
  • Research has shown that people who eat a lot of high-mercury fish frequently can experience nervous system damage and can suffer from a variety of ailments, including sleep disturbance, headache, fatigue, difficulty with memory and concentration, poor coordination and neuropathy (Hightower 2003, Silbernagel 2011, Groth 2011). (ewg.org)
  • A pilot study was done to find out if high fructose corn syrup contains mercury, and the results of the study done on corn syrup samples taken from three different manufacturers did detect mercury. (mnn.com)
  • Given how much high-fructose corn syrup is consumed by children, it could be a significant additional source of mercury never before considered. (mnn.com)

  • We measured the concentration of mercury using three different quantitative chemical methods in our labs in Odense and Řež, and all tests revealed the same result: that mercury concentrations were not sufficiently high to have caused his death,' says Dr Rasmussen. (phys.org)
  • In fact, chemical analyses of the bones indicate that Tycho Brahe was not exposed to an abnormally high mercury load in the last five to ten years of his life,' continues Dr Rasmussen, who analysed the bone samples using cold vapour atomic absorption spectroscopy at the University of Southern Denmark. (phys.org)
  • They reflect the mercury load in the last approximately eight weeks of Tycho Brahe's life, and these analyses show that mercury concentrations fell from the high end of the normal level eight weeks before death to the low end of the normal level in the last two weeks before death,' explains Dr Kučera. (phys.org)
