  • Remediation of mercury contaminated industrial site for future expansion - case study

    70,000 tons of mercury contaminated soil and building rubble have to be cleaned in an industrial facility in the south of France until 2013. For the realization of this remediation work, an econ industries VacuDry® 12,000 has been in operation since early 2011. After the treatment the mercury free soils can be re-used on-site as building material. A similar but smaller econ industries ...

  • Mercury Spill Control Procedures

    Mercury is a dangerous neurotoxin that can have damaging affects on both the central nervous system and renal system of humans. Exposure to mercury can cause serious developmental delays in children, and high level exposure is life threatening. When exposed to air, mercury vaporizes, readily becoming a dangerous aerosol that can be absorbed into the lungs and spread throughout the body. This is ...


  • Mercury Spill Control Procedures

    Mercury is a known neurotoxin that is extremely toxic even in small amounts. It directly affects the central nervous and renal systems, causing developmental delays, motor and brain problems like those associated with autism. Mercury"s hidden danger also lies in when at room temperature, when exposed it vaporizes readily. Once ...

  • Predictors of mercury spatial patterns in San Francisco Bay forage fish

    Pollution reduction efforts should be targeted towards those sources that result in the highest bioaccumulation. For mercury (Hg) in estuaries and other complex water bodies, carefully designed biosentinel monitoring programs can help identify predictors of bioaccumulation and inform management priorities for source reduction. We employed a probabilistic forage fish Hg survey with hypothesis ...

  • Critical perspectives on mercury toxicity reference values for protection of fish

    Environmental management decisions at mercury‐contaminated sediment sites are predicated on the understanding of risks to various receptors, including fish. Toxicity reference values (TRVs) for interpreting risks to fish have been developed to assess mercury concentrations in fish or fish prey. These TRVs were systematically evaluated based on several lines of evidence. First, their conceptual ...

  • Sulphate reducing bacteria to precipitate mercury after electrokinetic soil remediation

    Combined treatment with electroremediation and sulphate reducing bacteria (SRB) was tested in laboratory and pilot scale. The contaminated soil came from a chlor-alkali factory and contained about 100 mg/kg Hg. Iodide/iodine complexing agent was used to mobilize mercury. Mercury iodide complexes were moved to the anode solution using an electric field. The anode solution was then mixed with ...

  • New University of Minnesota study documents mercury vapor emission levels and need for safer packaging, storage and transportation of fluorescent lamps

    Results of a recent study conducted by the University of Minnesota School of Public Health, Division of Environmental Health Sciences suggest that most containers used for storage and transportation of used fluorescent lamps to recycling centers do not provide necessary levels of protection against mercury vapors emitted from broken lamps. The new study, published in the March issue of 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 ...

  • Heavy Metals Water Testing Powered by DNA

    Water pollution is a worldwide problem affecting developing and developed countries alike. Heavy metal contaminants are one prevalent type of water pollutant. They are persistent in the environment once d is charged and removal from source waters is necessary to ensure a clean drinking water supply. The problem of heavy metal pollution arises from several sources. Heavy metals such as uranium can ...

  • Ground Zero Air Quality Has A Long Way To Go! A Summary of Air Quality Testing in Surrounding Buildings

    There are still a wide range of concerns about air quality in the vicinity of Ground Zero. Many commercial and residential spaces have yet to be re-occupied. In only a few cases has any sort of inspection or testing been done to determine if they are safe to occupy. The greatest concerns are asbestos and the very irritating concrete dust that spread throughout lower Manhattan during the collapse ...

  • Environmental protection

    An analysis of the lighting industry shows a significant shift from the use of incandescent bulbs to fluorescent bulbs. Incandescent bulbs use more fossil fuel energy, cost more and are less effective than fluorescent bulbs, which produce more lumens. Usage of fluorescent bulbs, however, is not entirely without risk because they contain mercury, a chemical compound that can have debilitating ...


  • Cleaning & maintenance magazine

    An analysis of the lighting industry shows a trend away from incandescent bulbs to fluorescent bulbs. Incandescent bulbs use more energy and are more costly and less effective than fluorescent bulbs in the amount of artificial light they produce, as fluorescents produce more lumens than incandescents. Using fluorescent bulbs, however, is not entirely without risk because they contain mercury, a ...


  • Yucca Mountain Project, Nevada -

    Wells J-12 and J-13 are located in Area 25 of the Nevada Test Site near Mercury, Nevada. These wells supply potable water for the Yucca Mountain Project. Water-quality analyses revealed that arsenic concentrations exceeded the new maximum contaminant level (MCL). Before choosing a technology, the site manager, Bechtel SAIC, contracted with Dr. Dennis A. Clifford, University of Houston, and a team ...
