  • 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 Rising – Enviro Technology and mercury monitoring

    The first global treaty on mercury has put the metal firmly on the emissions monitoring agenda in 2013.  The Minamata Convention – which binds governments in over 140 countries to actively prevent mercury emissions and releases – was signed in January 2013. Mercury has long since been recognised as a chemical of global concern due to both its ability to travel long distances in ...

  • Momentum builds for ‘Mercury 2013’

    Mercury is moving towards the top of the agenda for regulatory bodies and interest from the public domain is growing. The United Nations Environment Program (UNEP) now defines mercury as “the pollutant of greatest concern”. In response to this, the organisers of the 11thInternational Conference on Mercury as a Global Pollutant (ICMGP) are finalising plans for an event that will bring ...

  • 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 ...

  • Better estimates of worldwide mercury pollution

    Original story at MIT News Once mercury is emitted into the atmosphere from the smokestacks of power plants, the pollutant has a complicated trajectory; even after it settles onto land and sinks into oceans, mercury can be re-emitted back into the atmosphere repeatedly. This so-called “grasshopper ...

  • Questions and answers on EU Mercury Policy

    What is mercury? Mercury is familiar to many as a silver-coloured liquid which expands and contracts in a thermometer to show the temperature. It is also known as “quicksilver” or "hydrargyrum" (i.e. liquid silver) and is represented by the symbol Hg. Mercury is the only metal that is liquid at ambient room temperature. It is a chemical element and therefore indestructible. ...

  • 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 ...

  • `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 ...

  • 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 ...

  • Economic benefits from reducing mercury emissions

    Large benefits can be achieved for society by reducing global emissions of mercury. Global savings of US$1.8-2.2 billion (€1.3-1.6 billion) can be made by reducing damage to IQ alone, according to recent research. Mercury emitted to the atmosphere primarily comes from combustion of fossil fuels (about 46 per cent of global mercury emissions) and high temperature processing of minerals, such as ...

  • Finding alternatives to mercury in small-scale gold mining

    Artisanal small-scale gold mining (ASM), largely practised in Asia, South America and Africa, contributes significantly to mercury emissions, both in the developing world and globally. A recent study investigates an alternative to using mercury in ASM. The EU Mercury Strategy1 recognises the need for global action to reduce mercury in the environment. This includes actions to help other countries ...

  • One step closer towards a global treaty on mercury

    The realisation of a global treaty on mercury is gaining momentum following a meeting of over 120 states in Japan. Governments met last week in the city of Chiba to continue negotiations on creating a global treaty on mercury and help reduce sources of mercury pollution. The meeting of the Intergovernmental Negotiating Committee (INC) - for which UNEP's Chemical Branch provides the Secretariat - ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Impact of mercury exposure from chlor-alkali plants

    An EU project, EMECAP1, has investigated levels of mercury exposure to populations living near chlor-alkali plants and the impact on human health. It found that the overall health risk was low, but was higher for some workers at the plants and for those who consumed contaminated fish or had mercury dental fillings. Mercury is a natural element but human activities, such as mining and ...
