Scientists reveal how organic mercury can interfere with vision More than one billion people worldwide rely on fish as an important source of animal protein, states the United Nations Food and Agriculture Organization. And while fish provide slightly over 7 per cent of animal protein in North America, in Asia they represent about 23 per cent of consumption. Humans consume low levels of methylmercury by eating fish and seafood. Methylmercury compounds specifically target the central...

Mercury In Pacific Fish On The Rise
2013-08-26 05:30:42

redOrbit Staff & Wire Reports - Your Universe Online The amount of toxic mercury found in Pacific Ocean fish is expected to increase over the next several decades, claims new research appearing in the August 25 edition of the journal Nature Geoscience. Using recently-developed isotopic measurement techniques, researchers from the University of Michigan and the University of Hawaii reported that they have discovered how methylmercury gets into open-ocean fish, thus infecting the...

More forms of mercury can be converted to deadly methylmercury than previously thought, according to a study published Sunday in Nature Geoscience. The discovery provides scientists with another piece of the mercury puzzle, bringing them one step closer to understanding the challenges associated with mercury cleanup. Earlier this year, a multidisciplinary team of researchers at Oak Ridge National Laboratory discovered two key genes that are essential for microbes to convert oxidized...

Legacy Mercury Levels In Fish, Environment Will Persist For Centuries
2013-07-09 09:29:11

April Flowers for redOrbit.com - Your Universe Online Significant reductions in mercury emissions will be necessary just to stabilize current levels of the toxic element in the environment, according to new research from a team led by Harvard University. Surface reservoirs, such as soil, air and water, hold an enormous amount of mercury from past pollution going back thousands of years. Scientists believe it will continue to persist in the ocean and accumulate in fish for decades to...

Urine, Hair Samples Overestimate Mercury Exposure From Dental Fillings

April Flowers for redOrbit.com - Your Universe Online A new study from the University of Michigan reveals that a common test currently used to determine mercury exposure from dental amalgam fillings may significantly overestimate the amount of toxic metal released from fillings. Although scientists agree that mercury vapor is released into the mouth by dental amalgam fillings, the amount released remains controversial, as does the question of the health risk posed by this release....

Mercury Pollution Clean Up Could Save The European Union Money

BioMed Central Cleaning up mercury pollution and reducing prenatal exposure to the neurotoxin methylmercury (MeHg) could save the European Union 10,000 million per year, finds a new study published in BioMed Central's open access journal Environmental Health. New estimates suggest that between 1.5 and 2 million children in the EU are born each year with MeHg exposures above the safe limit of 0.58µg/g and 200,000 above the WHO recommended maximum of 2.5µg/g. While some...

California Coastal Fog Contains Rising Levels Of Methylmercury
2012-12-05 10:58:48

Brett Smith for redOrbit.com - Your Universe Online Scientists from California have linked rising levels of methylmercury in their state´s coastal fog to upwelling from deep ocean water. Lead researcher Peter Weiss-Penzias, an environmental toxicologist at the University of California, Santa Cruz, was quick to point out that the amount of the toxic mercury compound detected in coastal fog is not a direct public health concern. "These are parts-per-trillion levels, so when we say...

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...
