    Sammanfattning : Accumulation of mercury (Hg) in soil originating from both natural and anthropogenic sources poses a major hazard to environmental and human health. Inorganic Hg(II) in soil can be transformed to highly toxic methylmercury (MeHg) mainly via methylating microorganisms. LÄS MER

  3. 3. Towards Abatement of Selected Emissions from Metals Manufacturing

    Detta är en avhandling från Stockholm : KTH

    Författare :Diana Orrling; KTH.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mercury; zinc; iron; copper; sulfur dioxide; adsorption; pollution; spectroscopy; thermal desorption; polycrystalline; surfaces; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Sammanfattning : Although the metallurgical industry has made great strides in the reduction of unwanted emissions to the atmosphere as a result of production processes, significant challenges still exist. From a global perspective, even large reductions in emissions per produced ton become immaterial when considering that the total world production of metals continues to increase. LÄS MER

  4. 4. Feasibility study of soil washing to remediate mercury contaminated soil

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Jingying Xu; Luleå tekniska universitet.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soil remediation; pH-dependentdissolution; organic matter; mobilisation; Other technology - Environmental engineering; Övriga teknikvetenskaper - Miljöteknik; Waste Science and Technology; Avfallsteknik;

    Sammanfattning : Mercury (Hg) cannot be degraded. Therefore only two principal processes are available for the treatment of Hg-contaminated soil: (1) the separation of Hg from the soil or (2) the stabilisation of Hg within the soil. Prior to selecting a suitable treatment technique, it is necessary to have an understanding of Hg behaviour in contaminated soil, i.e. LÄS MER

  5. 5. Fluvial transport and risk of mercury in a gold mining area

    Detta är en avhandling från Lund University

    Författare :Francisco Picado; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : My thesis is part of an overall environmental program evaluating the environmental and human health stress in areas of Nicaragua affected by anthropogenic emission of metals and man-made organic substances. I examine the fluvial transport of mercury contextually associated with the extent of the contamination and the observed human and environmental stress in a gold mining area. LÄS MER
