  • Mercury stabilization takes the sting out of mercury

    In elementary form, mercury is a danger to humans and the environment. But chemically bound to sulfur it loses its toxicity and can be disposed safely. The process which transforms the highly toxic metal into an unproblematic red powder is called mercury stabilization. As a specialist for cleaning mercury contaminated soil and waste by vacuum distillation econ also offers a process for mercury ...

  • Measuring total mercury due to small-scale gold mining activities to determine community vulnerability in Cihonje, Central Java, Indonesia

    This research is comparative study of gold mining and non-gold mining areas, using four community vulnerability indicators. Vulnerability indicators are exposure degree, contamination rate, chronic, and acute toxicity. Each indicator used different samples, such as wastewater from gold mining process, river water from Tajum river, human hair samples, and health questionnaire. This research ...

  • Ghostbusters won’t answer the phone

    A Supreme Court ruling that undermined a federal rule targeting mercury pollution will not affect the Obama administration’s plan to limit greenhouse gas emissions to slow the effects of global warming, the head of the Environmental Protection Agency said Tuesday. EPA Administrator Gina McCarthy said she was disappointed with last week’s court ruling, but said comparing the mercury ...

  • An environmental problem hidden in plain sight? Small Human‐made ponds, emergent insects, and mercury contamination of biota in the Great Plains

    Mercury (Hg) contamination of small human‐made ponds and surrounding terrestrial communities may be 1 of the largest unstudied Hg‐pollution problems in the United States. Humans have built millions of small ponds in the Great Plains of the United States, and these ponds have become contaminated with atmospherically deposited mercury. In aquatic ecosystems, less toxic forms of Hg deposited from ...

  • Understanding aqueous trace metal characteristics from industrial sources in China

    Trace metals are a group of toxic pollutants that can cause serious damage to ecosystems and humans. To determine the distribution characteristics of aqueous trace metal contamination and identify critical pollution sources, it is necessary to develop a detailed estimation of trace metal emissions. By considering emission-related factors in each industrial sector, we estimate that the ...

  • Mercury – The Facts, Myths and Clean Up Tips!

    Mercury, the facts. Mercury is an element (Hg on the periodic table) found naturally in the environment. Mercury emissions can come from both natural and man-made sources. It is commonly used in mercury arc lamps for UV curing, however this is a very minimal amount (as little as 5mg) and is used in the lamp to increase the voltage. Due to the harmful effects of Mercury, many ...

  • Effects of macrophytes on the fate of mercury in aquatic systems

    Vegetated and shallow areas such as wetlands and salt marshes but also freshwater lakes and rivers have been identified as hotspots for Hg methylation. The presence of aquatic macrophytes, the predominant primary producers in shallow waters, play an important but still poorly understood role in the fate of Hg in in these environments. The present review focuses on the influences of macrophytes ...

  • Interactions between mercury and phytoplankton: Speciation, bioavailability and internal handling

    In the present review, key interactions between Hg and phytoplankton are described and discussed in order to highlight the role of phytoplankton in the biogeochemical cycle of Hg and to understand direct or indirect Hg effects on them. Phytoplankton are exposed to various Hg species in surface waters. By Hg uptake, phytoplankton affect the concentration, speciation and fate of mercury in ...

  • Will the new global mercury treaty be effective?

    Original story at MIT News MIT researcher Noelle Selin assesses the challenges of implementing the first global mercury treaty. After four years of negotiations, delegates from more than 140 countries met last January to finalize the first global treaty to mitigate and prevent mercury pollution, the ...

  • Overview of mercury control in coal-fired power plants

    During combustion, the mercury (Hg) in coal is volatilized and converted to elemental mercury (Hg0) vapor in the high temperature regions of coal-fired boilers. As the flue gas is cooled, a series of complex reactions begin to convert Hg0 to ionic mercury (Hg2+) compounds and/or Hg compounds (Hgp) that are in a solid-phase at flue gas cleaning temperatures or Hg that is adsorbed onto the surface ...

  • Sources of mercury in a contaminated stream—implications for the timescale of recovery

    Mercury contamination in East Fork Poplar Creek in Tennessee arises from dissolved mercury exiting a headwater industrial complex and residual mercury in the streambed and soil throughout the watershed downstream. The headwater inputs generate chronic base flow concentrations of total mercury of about 1,000 ng/L, but most of the annual export of mercury from the system appears to originate ...

  • Environmental mercury in China: A review

    As a global pollutant, mercury can be transported over long distances and bioaccumulate. China is currently the greatest contributor to atmospheric Hg emissions and has the greatest intentional use of Hg. Mercuryin the Chinese environment is generally elevated, particularly in air and water bodies. Remote areas in China also show elevated Hg levels in air and water bodies compared with other ...

  • Fact Sheet: U.S. electricity markets increasingly favor alternatives to coal

    The U.S. electric power system is gradually shifting toward cleaner forms of generation. One sign of this transition is the declining use of coal for electric power production. In 2011, use of coal for U.S. power generation dropped to its lowest level in more than a decade, according to the federal government’s independent U.S. Energy Information Administration (EIA). In fact, the EIA ...

  • Column studies to determine mercury settling in road runoff

    A study was performed using a settling column to remove mercury (Hg) from road runoff. The emphasis was placed on the relationship between Hg removal and critical settling velocities, as well as the distribution of total suspended solids (TSS). The impact of rainfall characteristics and temperature on Hg removal was also discussed. Results indicated that Hg removal was significant within the ...

  • Fact sheet: EPA mercury rules and power reliability

    New rules from the U.S. Environmental Protection Agency to reduce mercury and other toxic air emissions will affect dozens of antiquated power plants currently operating without pollution controls. These rules have stirred debate in some circles as to whether retrofitting or retiring outdated plants will cause shortfalls in electricity capacity. How will EPA mercury rules influence the ...

  • EPA mercury rules: Keeping the lights on while removing toxics from our air

    Next week the U.S. Environmental Protection Agency is expected to finalize new rules to reduce mercury and other toxic air emissions that will affect dozens of antiquated power plants currently operating without pollution controls. These rules have stirred debate in some circles as to whether retrofitting or retiring outdated plants will cause shortfalls in electricity capacity. How will new EPA ...

  • Phytoremediation of mercury using Eichhornia crassipes (Mart.) Solms

    Roots of Eichhornia crassipes were found to accumulate maximum content of mercury (92.21 μg g−1 dry wt) in the roots of plants treated with 1000 μg l−1 concentration of mercuric acetate on 14th day of treatment. The bioconcentration factor (BCF) was found to be highest for lowest mercury concentrations ...
