STRASBOURG, France (AP) - The European Parliament on Tuesday backed plans to phase out the use of mercury in non-electrical measuring devices, with the exception of barometers and antique instruments. Medical devices such as thermometers and manometers would be covered by the legislation, which now goes to EU member states for assessment. The draft directive follows a call by the EU executive Commission to ban exports of mercury from 2011 as part of efforts to cut down the global supply of...

By Andrew Stern CHICAGO (Reuters) - Mercury built into older-model U.S. vehicles will be removed before they are melted down for scrap under an agreement announced on Friday, putting a small dent in a worsening global environmental threat. Droplets of airborne mercury emitted by coal-burning plants, waste incinerators and from small-stakes gold mining operations circle the Earth for up to a year before descending in rainfall, contaminating waterways and converting to a toxic form...

Scientists for years have been at a loss to explain unexpectedly high levels of mercury in fish swimming the rivers and streams of areas like eastern Oregon, far away from industrial sources of mercury pollution such as coal-fired power plants. New University of Washington research suggests mercury can be carried long distances in the atmosphere, combining with other airborne chemicals as it travels. These compounds are much more water-soluble and therefore are more easily removed from the...

By Maggie Fox, Health and Science Correspondent WASHINGTON (Reuters) - Levels of lead have dropped dramatically, exposure to second-hand smoke is down and most women are not burdened by unsafe levels of mercury, according to the latest U.S. government survey on chemical exposures. The third National Report on Human Exposure to Environmental Chemicals, released on Thursday by the Centers for Disease Control and Prevention, has details on 148 different chemicals found in the blood and urine...

SALT LAKE CITY (AP) -- Federal scientists studying the Great Salt Lake have found some of the highest levels of mercury ever measured anywhere - prompting concern about some of the migratory birds that feed on the lake's brine shrimp. U.S. Geological Survey and Fish and Wildlife Service researchers were initially gathering information on selenium in the lake, but decided also to test the samples for mercury. Concentrations of methylmercury - the element's most poisonous form - exceeded 25...

Mercury (element) Mercury, also called quicksilver, is a chemical element in the periodic table that has the symbol Hg (from the Greek hydrargyrum, for watery (or liquid) silver) and atomic number 80. A heavy, silvery, transition metal, mercury is one of only two elements that are liquid at room temperature (the other is bromine). Mercury is used in thermometers, barometers and other scientific apparatuses. Mercury is mostly obtained by reduction from the mineral cinnabar. Notable...

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
