• Inhalation Risk: A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20 °C.
• Effects of Short Term Exposure: The substance is irritating to the skin. Inhalation of high concentrations of the vapour may cause pneumonitis. This may result in death. The substance may cause effects on the central nervous system and kidneys. This may result in tremors and tissue lesions. The effects may be delayed. Medical observation is indicated.
• Effects of Long Term Exposure: The substance may have effects on the central nervous system and kidneys. This may result in irritability, emotional instability, tremors, mental and memory disturbances and speech disorders. May cause inflammation and discoloration of gums. Cumulative effects are possible. Animal tests show that this substance possibly causes toxic effects upon human reproduction.
• Uses: Some of the most important uses of mercury are in the electrical and electrolytic applications. A broad range of such applications include mercury batteries and cells in portable radios, microphones, cameras, hearing aids, watches, smoke alarms, and wiring and switching devices. Other notable applications are in mercury vapor lamps, fluorescent tubes and electrical discharge tubes. Mercury electrodes are widely used in electrolytic cells. Mercury cathodes are employed in the electrolysis of sodium chloride to produce caustic soda and chlorine. Another major use, as mentioned earlier, is in thermometers, manometers, barometers and other pressure-sensing devices. Mercury also is used as a catalyst in making urethane foams and vinyl chloride monomers. Mercury and its compounds long have been used as fungicides in paints and in agriculture. Mercury compounds are used in medicines, pigments and analytical reagents. In mercury arc lamps producing ultraviolet rays; in mercury boilers; manufacture of all mercury salts, mirrors; as catalyst in oxidation of organic Compounds; extracting gold and silver from ores; making amalgams, electric rectifiers, mercury fulminate; also in dentistry; in determining N by Kjeldahl method, for Millon's reagent; as cathode in electrolysis, electroanalysis, and many other uses. Also in pharmaceuticals, agricultural chemicals, anti-fouling paints. Cadmium is used in electroplating, in nickelcadmiumstorage batteries, as a coating forother metals, in bearing and low-meltingalloys, and as control rods in nuclear reactors.Cadmium compounds have numerousapplications, including dyeing and printingtextiles, as TV phosphors, as pigments andenamels, and in semiconductors and solarcells. Vegetables and cereals are the main sourcesof dietary Cd while meat and fish contain themetal to a lesser extent. Amalgams, catalyst, electrical apparatus, cathodes for production of chlorine and caustic soda, instruments (thermometers, barometers, etc.), mercury vapor lamps, extractive metallurgy, mirror coating, arc lamps, boilers, coolant, and neutron absorber in nuclear power plants. Electrical apparatus; measurement and control systems such as thermometers and sphygmomanometers; agricultural and industrial poisons; catalyst; antifouling paint; dental practice; gold mining
• Description: Elemental mercury, a silver-white metal, is also known ‘quicksilver’ or ‘hydrargyrum.’ Mercury has been discovered in Egyptian tombs dating as far back as 1500 BC. The chemical symbol, Hg, is derived from the Greek word hydrargyros, meaning ‘water silver.’ Mercury was known in antiquity and used by alchemists. Its neurological effects were recognized early, and its use in the hat-making trade gave rise to the phrase ‘mad as a hatter.’ Mercury has been used commercially and medically for centuries. In the past it was a common constituent of many medications, for example, it was used in the treatment of syphilis. Use of mercury has been drastically reduced in recent years. Within the twentieth century, mercury used to be in every physician’s or pharmacist’s armamentarium, for example, calomel was commonly used in infant teething powders in the 1930s and 1940s.
