  • 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 and other Contaminants in Common Loons Breeding in Atlantic Canada

    Common loons (Gavia immer) were studied to assess the biomagnification of persistent contaminants in lake ecosystems in Atlantic Canada. Forty-two breeding adults and 20 juvenile loons were captured in August, 1995–1997 on lakes in four areas of southern New Brunswick (Lepreau and Fundy National Park) and Nova Scotia (Halifax and Kejimkujik National Park). Blood samples were collected for ...

  • Evaluation of zebra mussels (Dreissena polymorpha) as biomonitors of mercury contamination in aquatic ecosystems

    Zebra mussels have invaded many lakes in the United States and could be a useful tool for monitoring responses of aquatic biota to changes in mercury loading. The goal of the present study was to evaluate zebra mussels for use as a biomonitor of mercury contamination by comparing zebra mussel mercury concentrations between a lake with only indirect atmospheric mercury contamination (Otisco ...

  • Remediation of the mercury-contaminated sediments in Svartsjoarna with Geotube - Case Study

    The Challenge Svartsjoarna in Sweden are located near Paulistrom. Through the lake, a small river runs into the river Eman. This Eman river is considered to be one of the most valuable water courses in Sweden. The river has a very high diversity of fish species and animal like otter. Some parts of the river have very well developed meander systems. For these reasons, a remediation had to ...

  • Mercury in fish: a critical examination of gold mining and human contamination in Ghana

    This study examines the knowledge of miners, fishermen, fish sellers, and fish buyers regarding the linkages between elemental mercury, methylmercury, fish consumption, and health risks in and around mining areas in Ghana. While findings suggest that a clear grasp of the impacts of mercury on human health is lacking, few potentially polluted fish are consumed in the mining areas. Most customers ...

  • 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 ...

  • 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 ...

  • 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 ...


  • Detecting Mercury in Water

    Determination of Mercury (Hg) in Water by Hand-Held, Portable Cold Vapor Atomic Fluorescence SpectrometryWater is the most familiar and most abundant compound on Earth, making up 71% of its surface area.[1]It is a vital component for all known forms of life and is the aquatic habitat for thousands of species of microalgae, fish and shellfish. [2] With the presence of running water in our ...

  • 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 ...


  • Influence of a chlor‐alkali Superfund site on mercury bioaccumulation in periphyton and Low‐trophic level fauna

    In Berlin, NH, the Androscoggin River flows adjacent to a former chlor‐alkali facility that is a US EPA Superfund site and source of mercury (Hg) to the river. A study was conducted to determine the fate and bioaccumulation of methylmercury (MeHg) to lower trophic‐level taxa in the river. Surface sediment directly adjacent to the source showed significantly elevated MeHg (10–40x increase, ...

  • Critical review of mercury SQVs for the protection of benthic invertebrates

    Sediment Quality Values (SQVs) are commonly used – and misused – to characterize the need for investigation, understand causes of observed effects, and derive management strategies to protect benthic invertebrates from direct toxic effects. We compiled > 40 SQVs for mercury, nearly all of which are “co‐occurrence” SQVs derived from databases of paired chemistry and benthic invertebrate effects ...

  • The multiple stressor ecological risk assessment for the mercury contaminated South River and upper Shenandoah River using the Bayesian Network‐Relative Risk Model

    We have conducted a regional scale risk assessment using the Bayesian Network Relative Risk Model (BN‐RRM) to calculate the ecological risks to the South River and upper Shenandoah River study area. Four biological endpoints (smallmouth bass, white sucker, Belted Kingfisher and Carolina Wren) and four abiotic endpoints (Fishing River Use, Swimming River Use, and Boating River Use and Water ...

  • Properties and Behavior of Inorganics in Contaminated Soil

    Often, specific technologies may be ruled out, or the list of potential technologies may be immediately narrowed, on the basis of the presence or absence of one or more of the chemical groups. The relative amounts of each may tend to favor certain technologies. Metals may be found in the elemental form, but more often they are found as salts mixed in the soil. At the present time, treatment ...

  • 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 ...

  • Patterns of Mercury Deposition and Concentration in Northeastern North America (1996–2002)

    Data from 13 National Atmospheric Deposition Program Mercury Monitor Network (NADP/MDN) monitoring stations (1996–2002) and the Underhill (VT) event-based monitoring site (1993–2002) were evaluated for spatial and temporal trends. More precipitation and mercury deposition occurred in the southern and coastal MDN sites, except for the Underhill site, which received more mercury deposition than ...

  • Mercury distribution in soils and plants surrounding an industrial area in the South of Italy

    Soil and plant samples, collected nearby an industrial site in the South of Italy, were investigated to monitor the presence and distribution of mercury (Hg). The Hg contamination in soils ranged from ca. 1.5 to 50 mg kg−1 and was limited to the first 0.5 m. In general, high spatial distribution heterogeneities were observed. The spontaneous flora analysed contained an average of 0.2 mg ...

  • The role of natural purified humic acids in modifying Mercury accessibility in water and soil

    Received for publication April 17, 2008. Contamination of soils with mercury can be a serious problem. It can be mobilized or stabilized by humic substances (HS) containing binding sites with reduced sulfur that can have different binding capacities for CH3Hg+ and for Hg2+. In this work we investigated the influence of different humic acids (HAs, extracted from lignite, compost, and forest soil) ...
