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)

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... view more (2003-06-10)

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)

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)

Mopping up mercury - a new solution to an old problem
A pilot plant employing a new type of bioreactor has successfully been used to treat mercury-contaminated wastewater in Germany. Dr Irene Wagner-Döbler and colleagues from the GBF National Research Centre for Biotechnology, Germany, developed the technical scale plant based on previous work... view more (2001-04-01)

Power plants are major influence in regional mercury emissions
The amount of mercury emitted into the atmosphere in the Northeast fluctuates annually depending on activity in the electric power industry, according to researchers at the Yale School of Forestry & Environmental Studies.   view more (2006-07-24)

Groundbreaking Canada-US study proves link between emissions and mercury pollution in fish
A groundbreaking environmental study to be published in a prestigious American science journal proves that mercury atmospheric emissions will end up in fish in as little as three years.   view more (2007-09-18)

Gold nanoparticles help detect a toxic metal -- mercury
With gold nanoparticles, DNA and some smart chemistry as their tools, scientists at Northwestern University have developed a simple "litmus test" for mercury that eventually could be used for on-the-spot environmental monitoring of bodies of water, such as rivers, streams, lakes and... view more (2007-04-27)

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)

Mercury contamination found in stranded Victorian dolphins
Monash University research into heavy metal contaminant levels in dolphins from Port Phillip Bay and the Gippsland Lakes has revealed high mercury levels may be a contributing factor to dolphin deaths.   view more (2008-06-10)

International team shows mercury concentrations in fish respond quickly to increased deposition
A joint Canadian-American research team have, for the first time, demonstrated that mercury concentrations in fish respond directly to changes in atmospheric deposition of the chemical.   view more (2007-09-18)

Nanoporous 'sponge' removes mercury from offshore produced waters
Contaminated water resulting from offshore oil and gas platform drilling contains mercury and other toxic heavy metals.   view more (2006-03-30)

Plant pathologists evaluate eco-friendly alternatives to methyl bromide
Alternatives to a powerful pesticide that was found be an ozone depletor are now being evaluated in agricultural production areas of Florida, say plant pathologists with USDA's Agricultural Research Service.   view more (2005-06-14)

Prenatal Exposure To Mercury In Fish Not Associated With Impaired Neurodevelopment (p 1667, 1686)
Authors of a longitudinal study investigating a possible link between prenatal mercury exposure from ocean fish and impaired neurodevelopment in children report their latest findings in this week's issue of THE LANCET. The results confirm earlier findings that prenatal exposure to mercury in the... view more (2003-05-14)

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... view more (1999-06-08)

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... view more (2002-08-05)

Clay for cleaner production of solvent
Dutch researcher Ferry Winter has developed a heterogeneous catalyst for the production of the industrially important solvent methyl isobutyl ketone. With the new catalyst the production process is more environmentally-friendly. The catalyst consists of hydrotalcite, a naturally-occurring clay.   view more (2006-02-16)

New study shows fish respond quickly to changes in mercury deposition
Reducing atmospheric mercury emissions should quickly reduce mercury levels in lake fish, according to a three-year study published this week in the Proceedings of the National Academy of Science.   view more (2007-09-20)

Novel enzyme offers new look at gene regulation
Scientists at the University of North Carolina at Chapel Hill have purified a novel protein and have shown it can alter gene activity by reversing a molecular modification previously thought permanent.   view more (2005-12-21)

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... view more (2002-11-27)

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)

Hotspots of mercury contamination identified in eastern North America
A US and Canadian research team surveying mercury contamination in fish and birds in the northeastern United States and southeastern Canada has identified five "hotspots" where concentrations of the element exceed those established for human or wildlife health.   view more (2007-01-03)

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... view more (1999-09-13)

Waterborne carbon increases threat of environmental mercury
