A study by University of Michigan researchers offers new insight into what happens to mercury deposited onto Arctic snow from the atmosphere. The work also provides a new approach to tracking mercury's movement through Arctic ecosystems. Mercury is a naturally occurring element, but some 2000 tons of it enter the global environment each year from human-generated sources such as coal-burning power plants, incinerators and chlorine-producing plants. "When released into the atmosphere in its...

With growing concerns about the effects of global warming on polar bears, it's increasingly important to understand how other environmental threats, such as mercury pollution, are affecting these magnificent Arctic animals. New research led by biogeochemists Travis Horton of the University of Canterbury and Joel Blum of the University of Michigan lays the groundwork for assessing current and future effects of mercury deposition and climate change on polar bears. The study appears in the...

GENEVA, Switzerland, Nov. 18 /PRNewswire-USNewswire/ -- Hailed as "a breakthrough" by Green Groups, an agreement in concept was reached yesterday by a World Health Organization (W.H.O.)-convened international expert group, supporting the "phase down" of dental mercury use worldwide. [1] However, the groups note that there is still much work to be done in deciding how and when a global dental amalgam phase down will occur. "As a first step, I'm pleased to positively support a global 'phase...

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...
