  • Record elevation set for Tekran: ambient air monitoring in the clouds

    The Tekran ambient air mercury speciation system has been taken to new heights. The Tekran 2537-1130-1135 speciation system has been successfully deployed for long-term monitoring at an elevation of 3810 meters (12,500 ft) at Mt. Waliguan, China. This beats the old record of 2763 meters (9065 ft) at Mt. Bachelor set by Dr. Daniel Jaffe’s Research Group. The installation and ongoing ...

  • World governments support breakthrough agreement on mercury

    Defying expectations, world environmental ministers have agreed to begin negotiating a treaty to control global mercury pollution. The decision represents the consensus of the more than 140 countries gathered here for the 25th UNEP Governing Council meeting. “This consensus is a huge breakthrough,” said Elena Lymberidi – Settimo of the European Environmental Bureau and the Zero Mercury Working ...

  • Forest fires increase mercury emissions

    Mercury is a global pollutant arising from many sources, including biomass burning (BMB), which includes both wildfires and intentional fires to clear land. A recent study estimates that mercury emissions from BMB make up 8 per cent of total global mercury emissions. Mercury emissions from BMB have received growing attention. Forests in particular act as mercury sinks because atmospheric mercury ...

  • `Chemical fingerprints` could reveal source of mercury pollution

    Scientists have described a new method for tracking down the source of mercury pollution from burning coal. By analysing the chemistry of the pollution, it is possible to identify which region the coal was originally from. Mercury pollution in the atmosphere comes mainly from coal-fired power stations and chemical plants. Mercury is naturally present in coal and is emitted when it is burned as ...

  • Study reveals mercury contamination in Fish Nationwide

    Scientists detected mercury contamination in every fish sampled in 291 streams across the country, according to a U.S. Geological Survey study released today. About a quarter of these fish were found to contain mercury at levels exceeding the criterion for the protection of people who consume average amounts of fish, established by the U.S. Environmental ...

  • Arctic Council States welcome Minamata Convention on Mercury

    The Minamata Convention, a global agreement "to protect human health and the environment from anthropogenic emissions and releases of mercury and mercury compounds," will be opened for signature in Minamata, Japan from October 9-11. The Arctic Council States and Permanent Participant organizations welcome the new agreement, recognizing that the Council's scientific work has contributed greatly to ...

  • New England Fish Chowder, Hold the Mercury, Please

    BOSTON, Massachusetts, December 31, 2007 (ENS) - A plan by the Northeast states to lower mercury levels in fish throughout New England and New York has been approved by the U.S. Environmental Protection Agency, EPA. The plan calls for a 98 percent reduction from 1998 levels of mercury from atmospheric sources in order to make mercury levels in fish low enough for the states to lift fish ...

  • Johnson Matthey Licenses DOE Patent to Remove Mercury and Arsenic from New IGCC Coal Power Plants

    MALVERN, PA– Johnson Matthey announced today that it has been granted an exclusive license by the U.S. Department of Energy’s National Energy Technology Laboratory (NETL) for its high temperature sorbent technology and patent to remove mercury, arsenic and potentially selenium and cadmium from syngas produced by coal gasification.  This license was a natural extension of a two-year ...

  • Lumex Instruments Takes Part in Making Mercury History

    Minamata disease is one of the most notorious ecological catastrophes of the 20th century. Discharge of mercury-containing effluent by the "Chisso" chemical plant to the Minamata Bay in Kumamoto Prefecture, Japan, gave rise to a dangerous syndrome that seriously affects the central nervous system due to the toxicity of methylmercury, which gets into the body with contaminated food. In ...

  • Researchers reveal strategies for mercury reduction in time for negotiations

    MIT, Harvard professors map future trends, reveal ways to reduce mercury levels on eve of final international meeting for mercury control. Written by Vicki Ekstrom.You can read the original story in MIT NewsInternational negotiators ...

  • Understanding the movement of mercury in the atmosphere

    In order to reduce mercury pollution, we need to understand its movement in the global atmosphere. A UN report summarises current information on mercury transport in the atmosphere and indicates that intensive global monitoring is needed to inform and evaluate policy. As a result of EU policy1, European emissions of mercury have dropped considerably in recent decades, decreasing by about 60 per ...

  • Mercury Hotspots Detected in Eastern U.S. and Canada

    WASHINGTON, DC (ENS) – U.S. sources of mercury emissions, particularly coal-fired power plants, are the major cause of five biological mercury hotspots identified in New England, New York and Nova Scotia, according to two new scientific studies. The findings indicate the U.S. Environmental Protection Agency, EPA, is greatly underestimating local and regional impacts of mercury ...

  • European successes in reducing toxic metal pollutants

    Strategies in Europe to protect human health and the environment from the harmful effects of heavy metals have been successful in reducing atmospheric emissions of cadmium, lead and mercury, according to a recent study. The study suggests further reductions are possible. Heavy metals are toxic to human health and can damage the environment. For example, if large amounts of lead build up in the ...

  • Landmark US Geological Survey study demonstrates how methylmercury, known to contaminate seafood, originates in the ocean

    A new landmark study published today documents for the first time the process in which increased mercury emissions from human sources across the globe, and in particular from Asia, make their way into the North Pacific Ocean and as a result contaminate tuna and other seafood. Because much of the mercury that enters the North Pacific comes from the atmosphere, scientists have predicted an ...

  • Use of mercury in gold mining stirs controversy in Brazil

    Scientists in Brazil have expressed concern that new regulations in the country's Amazonas state continue to permit the use of mercury in gold mining, and have put forward what they say are more environmentally-friendly alternatives. Mercury is used mainly in small-scale 'artisanal' mining, using amalgamation processes that extract gold from other minerals by binding it to the mercury, and then ...

  • EPA Everglades Study Shows Contamination has Declined, but Risks Still Remain

    (ATLANTA – September 19, 2007) The U.S. Environmental Protection Agency released a report today documenting the ecological condition of the entire 2,063-square-mile freshwater portion of the publicly- owned Everglades. The report documents the third phase of an 11-year study of the Everglades marshes, which determined that mercury in prey fish is declining, but still elevated, while phosphorous ...

  • UNEP and Brazil Launch Research Project to Manage Mercury Risks

    Brazil's Ministry of Environment (MoE) and the United Nations Environment Programme (UNEP) today launched a new research project to help manage environmental health risks from mercury.

  • Panama Breaking New Ground on Climate Change Adaptation and Mitigation

    Environmental sustainability is gaining traction on Panama's political agenda. The announcement of the upgrade of the National Environmental Authority (ANAM) to ministerial status is being followed by a public debate on how to better integrate environmental considerations into public policies.

  • Safeguarding human health from the effects of mercury

    Mercury is widely considered to be among the highest priority environmental pollutants of concern on the global scale. Although occupational exposure to inorganic mercury is a continuous problem, possible effects on broader sections of the population resulting from widespread dispersal of mercury in the environment has become a major concern in recent years. Mercury has been targeted by agencies ...
