Mercury in Mackenzie River delta dramatically higher than previously believed
University of Alberta researchers conducting a water study in the Mackenzie River Delta have found a dramatically higher delivery of mercury from the Mackenzie River to the Arctic Ocean than determined in previous studies. view more (2009-06-17)
Exposure to mercury before birth may cause high blood pressure
Increased exposure to mercury can occur in communities whose diet is based on seafood. Following a study in the Faeroes,2 where the traditional diet includes a large element of whale-meat, an international research project co-funded by the European Union under its Environment and Climate research programme, examined 149 children from a fishing... view more...

Dartmouth researchers alarmed by levels of mercury and arsenic in Chinese freshwater ecosystem
A team of researchers, led by biologists at Dartmouth, has found potentially dangerous levels of mercury and arsenic in Lake Baiyangdian, the largest lake in the North China Plain and a source of both food and drinking water for the people who live around it. view more (2008-01-10)
Higher levels of pollutants found in fish caught near a coal-fired power plant
Emissions from coal-fired power plants may be an important source of water pollution and fish contamination. view more (2007-11-07)
Dental Material Amalgam Is Not Guilty Of Disturbances
A careful study by a group of investigators of the University of Giessen suggests that there is no indication for mercury intoxication or amalgam allergy as a cause of somatic complaints. To deepen the understanding of the numerous unspecific complaints which are related to the dental material amalgam both in patients and physicians, an... view more... (2002-08-05)
Glowing Results-Pitt Researchers Use Fluorescence to Develop Fast, Simple Method for Detecting Mercury in Fish and Dental Fillings
Researchers at the University of Pittsburgh have developed a simple and quick method for detecting mercury in fish and dental samples, two substances at the center of public concern about mercury contamination. view more (2008-11-19)
High Mercury Count In Fish Linked To Heart Attack
People who eat fish with a raised mercury content run a greater risk of coronary heart disease than previously thought, an international team of researchers has found. Scientists from Edinburgh, Baltimore and seven other European countries say that mercury, which is found in certain fish from environmentally contaminated areas, may counteract the... view more...

MESSENGER flyby of Mercury
At 2:04 p.m. EST on Monday, MESSENGER skimmed 200 kilometers (124 miles) above the surface of Mercury in the first of three flybys of the planet. view more (2008-01-15)
Researchers Find Substantial Amount of Mercury Entering the Ocean through Groundwater
Researchers from the Woods Hole Oceanographic Institution (WHOI) have found a new and substantial pathway for mercury pollution flowing into coastal waters. Marine chemists have detected much more dissolved mercury entering the ocean through groundwater than from atmospheric and river sources. view more (2007-03-22)
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 more (2008-03-27)
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... view more... (1999-09-13)
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 more (2005-12-08)
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 more (2007-12-11)
Methods for monitoring CO2 emissions have limitations, inadequate for international climate treaty
Current methods for estimating greenhouse gas emissions have limitations that make it difficult to monitor CO2 emissions and verify an international climate treaty, says a new National Research Council letter report to the administrator of NASA, Charles F. Bolden Jr. view more (2009-08-03)
MESSENGER discovers an unusual impact basin on Mercury
A previously unknown, large impact basin has been discovered by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft during its second flyby of Mercury in October 2008. view more (2009-05-01)
Study finds mercury levels in children with autism and those developing typically are the same
In a large population-based study published online today, researchers at the UC Davis MIND Institute report that after adjusting for a number of factors, typically developing children and children with autism have similar levels of mercury in their blood streams. Mercury is a heavy metal found in other studies to adversely affect the developing... view more... (2009-10-20)
Materials expert denounces Norwegian ban on dental amalgam
In an editorial published today in the February issue of the Journal of Dental Research, Derek Jones, Professor Emeritus of Biomaterials, Dalhousie University (Halifax, NS, Canada), and Chair of the International Standards Organization's Technical Committee on Dentistry, denounces new Norwegian regulations governing the use of mercury that will... view more...

UT Knoxville and ORNL researchers reveal key to how bacteria clear mercury pollution
Mercury pollution is a persistent problem in the environment. Human activity has lead to increasingly large accumulations of the toxic chemical, especially in waterways, where fish and shellfish tend to act as sponges for the heavy metal. view more (2009-10-02)
Burning wetlands unleash sequestered mercury in wake of climate change
Climate change appears to be contributing to the waking of a dangerous sleeping giant in the most northern wetlands of North America - mercury. view more (2006-08-22)
Studies evaluating health effects of dental amalgam fillings in children confirm safety
For the first time at a major international meeting, scientists are reporting the results of the first-ever randomized clinical trials to evaluate the safety of placing amalgam fillings, which contain mercury, in the teeth of children. view more (2006-06-29)
