BANGKOK, Thailand, Oct. 23 /PRNewswire-USNewswire/ -- Today, world governments took the first significant steps towards a Legally Binding Treaty to control mercury pollution at a United Nations Environmental Program meeting in Bangkok, Thailand. Their recommendations now provide countries with a basis to head into the International Negotiating Committee (INC) meetings starting in Stockholm, June 2010. "We are happy that governments agreed on rules of procedures, which allow NGO...

U.S. scientists say they've found how bacteria convert methylmercury into a less-toxic form, allowing the bacteria to survive in mercury-rich environments. The discovery by scientists at the University of Tennessee-Knoxville and Oak Ridge National Laboratory may provide a solution for some mercury pollution in waterways, where fish and shellfish tend to act as sponges for the heavy metal. Mercury pollution is a significant environmental problem, said Professor Jeremy Smith, lead author of the...

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. It's that persistent and toxic nature that has flummoxed scientists for years in the quest to find ways to mitigate the dangers posed by the buildup of mercury in its most toxic form, methylmercury. A new discovery by scientists at the University of...

WASHINGTON, Sept. 17 /PRNewswire-USNewswire/ -- In the wake of President Obama's visit to a General Motors (GM) plant earlier in the week, his Administration and key states were warned today that GM would be excluded from the country's automotive mercury recycling program at the end of this year. The national administrator overseeing mercury recycling in automobiles made the announcement in an update to program participants this morning. In response, two allied environmental groups called...

In the open ocean, species of large predatory fish will swim and hunt for food at various depths, which leads to unique diets in these fish. Oceanographers and geologists in the School of Ocean and Earth Science and Technology (SOEST) at the University of HawaiÊ»i at Mānoa (UHM) and colleagues have found that those fish that hunt deeper in the open ocean have higher mercury concentrations than those that feed near the surface of the ocean because...

WASHINGTON, Aug. 24 /PRNewswire-USNewswire/ --Today, the $3 billion "Cash for Clunkers" program is expiring. The program provided $3,500-4,500 incentives for turning in less fuel-efficient vehicles to purchase new, more efficient ones. As of early Friday, the program had been a smash success, accounting for sales of 489,000 vehicles. On Thursday, in a radio interview, President Obama called the program "successful beyond anybody's imagination." At the same time old clunkers have poured...

Mercury levels in Utah's Great Salt Lake are the highest of any body of water in the United States, say scientists studying the effect on animal and plant life. All we know is that there is a problem out there, but there's more to understanding how to deal with it, said Manusel Pearce, a spokesman for the Great Salt Lake Alliance. A study now being completed could help show if mercury is drifting into Utah from Nevada's goldmines, and whether the 9 million to 12 million birds that migrate...

A new federal study suggests that fish cannot escape mercury pollution. The study, conducted by the U.S. Geological Survey, tested fish from nearly 300 streams across the country for traces of mercury, and found that every sampled fish contained the substance. Although all the fish had traces of mercury, only a quarter had levels considered unsafe for human consumption. Over a thousand fish were tested from 1998 to 2005 for the study. "This science sends a clear message that our country must...

U.S. scientists say they've found organic matter in water and sediment apparently play a key role in helping microbes convert mercury into a dangerous form. The finding by Duke University environmental engineers is said to be important because it could change the way mercury in the environment is measured and therefore regulated. The particular harmful form of the element, known as methylmercury, is a potent toxin for nerve cells, researchers said. When ingested by organisms, it is not...

Scientists say they've found a much higher level of mercury flowing from Canada's Mackenzie River into the Arctic Ocean than found by previous studies. University of Alberta researcher Jennifer Graydon and her colleagues analyzed water in the Mackenzie River as it flowed north into the Beaufort Sea. She collected samples for three months and discovered the total amount of mercury exported from the river during that period was equal to an entire year's worth of mercury calculated in previous...

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...
