mercury contaminated soil Articles

  • Mercury

    Abstract Mercury is a naturally occurring metal found in the Earth’s crust. At high doses, mercury is known to cause adverse human health effects. Over the past several years, EPA (the Environmental Protection Agency) has focused on mercury exposures because of its potential to cause adverse human health and environmental effects, and because of its persistence and widespread distribution in the ...

  • 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 ...

  • Accumulation of mercury and cadmium in rice from paddy soil near a mercury mine

    Paddy soil and rice (Oryza sativa L.) in the Wanshan mining area in Guizhou province have been contaminated by toxic trace metals such as cadmium (Cd) and mercury (Hg). This study examined correlations between the types and physico‐chemical parameters of the soil and the contents of trace metals and the different forms of Hg in rice. The study also carried out an assessment of the health risks ...

  • Mercury Removal

    The Adventus Mercury Removal AdvantageResponsible environmental experts in the academic, business and regulatory communities are increasingly more worried about the high levels of mercury contamination affecting many parts of the world. The international community is focusing their attention on this growing problem and EHC-M will clearly help, as it is perfectly suited for treating environments ...


  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • Soil CEC and Selectivity Sequence for Mercury (II) Ion

    Abstract Mercury is one of the most hazardous air and water pollutants. Since the issuance of the Clean Air Mercury Rule for coal-fired electric boiler utilities in March 2005, numerous scientific researches have focused on the fate and transport of mercury in both atmosphere and aqueous environment. The issue of aqueous mercury transport as the major mercury transport mechanism becomes more and ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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) ...

  • 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 ...

  • 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 ...

  • 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 ...


  • 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 ...

  • 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 ...


  • Specific and exchange adsorption of mercury (II) on Ca-saturated kaolinitic soils in Central Nigeria

    We studied the adsorption of Hg (II) in typical tropical soils in Central Nigeria. Results suggest that more Hg (II) is adsorbed specifically than by the reversible, cation exchange process, with the adsorption isotherms predominantly Langmuirian in form. Considering the acid, low organic matter content and kaolinitic clay nature of the soils, the specific adsorption is traceable to outer-sphere ...

  • Seasonal and flow‐driven dynamics of particulate and dissolved mercury and methylmercury in a stream impacted by an industrial mercury source

    Sediments and floodplain soils in the East Fork Poplar Creek (EFPC) watershed in Oak Ridge, TN, are contaminated with high levels of mercury (Hg) from an industrial source at the headwaters. While baseflow conditions have been monitored, concentrations of Hg and methylmercury (MeHg) during high‐flow storm events, when the stream is more hydrologically connected to the floodplain, have yet to ...
