Dental chair a possible source of neurotoxic mercury waste
Mercury is a large component of dental fillings, but it is not believed to pose immediate health risks in that form. When exposed to sulfate-reducing bacteria, however, mercury undergoes a chemical change and becomes methylated, making it a potent, ingestible neurotoxin. View News Article (2008-03-27)


Mercury's magnetic field tells scientists how its interior is different from Earth's
Earth and Mercury are both rocky planets with iron cores, but Mercury's interior differs from Earth's in a way that explains why the planet has such a bizarre magnetic field, UCLA planetary physicists and colleagues report. View News Article (2014-07-30)


New low-cost, nondestructive technology cuts risk from mercury hot spots
Hot spots of mercury pollution in aquatic sediments and soils can contaminate local food webs and threaten ecosystems, but cleaning them up can be expensive and destructive. View News Article (2013-10-25)


CU-Boulder space scientists set for second spacecraft flyby of Mercury
NASA's MESSENGER spacecraft, which is toting an $8.7 million University of Colorado at Boulder instrument to measure Mercury's wispy atmosphere and blistering surface, will make its second flyby of the mysterious, rocky planet Oct. 6. View News Article (2008-10-01)


MERCURY POLLUTION IN BOLIVIAN RIVERS
Mercury contamination in rivers of the Amazon Basin is increasingly a cause for concern. The region's soils, naturally containing abundant heavy metals, are one source of this mercury. Gold mining, which is an increasing activity in the Amazon region since gold fever took hold in the 1970s, is the additional major source. Many studies have been conducted on this problem in Brazil and French... View News Article (1999-09-13)


High levels of mercury found in Cataraqui River: Queen's study
The Inner Harbour on the Cataraqui River in Kingston, Ont., has mercury levels in sediment more than two times the Canadian government's most severe effect limits, according to a Queen's University study. View News Article (2010-03-18)


Succimer found ineffective for removing mercury
Succimer, a drug used for treating lead poisoning, does not effectively remove mercury from the body, according to research supported by the National Institutes of Health. View News Article (2010-10-25)


Mercury in atmosphere could be washed out more easily than earlier believed
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. View News Article (2005-12-08)


Atmospheric Mercury Has Declined -- But Why?
The amount of gaseous mercury in the atmosphere has dropped sharply from its peak in the 1980s and has remained relatively constant since the mid 1990s. This welcome decline may result from control measures undertaken in western Europe and North America, but scientists who have just concluded a study of atmospheric mercury say they cannot reconcile the amounts actually found with current...

Waterborne carbon increases threat of environmental mercury
Mercury is a potent neurotoxin and a worrisome environmental contaminant, but the severity of its threat appears to depend on what else is in the water. View News Article (2007-12-11)
