  1. 1. Remediation of mercury contaminated soil and biological mercury methylation in the landscape

    Författare :Jingying Xu; Stefan Bertilsson; Andrea Garcia Bravo; Dario Acha; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mercury contamination; Soil remediation; Methylmercury; Mercury methylation; hgcA; Community composition; Bacteria; Landscape; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    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. 2. Decontamination of Mercury from Aqueous Systems via Electrochemical PtHg4 Alloy Formation

    Författare :Vera Roth; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mercury; Platinum; Alloy Formation; Electrochemistry; Mercury Removal;

    Sammanfattning : Mercury is worldwide a severe heavy metal pollutant and a serious threat to human health and ecosystems. Mercury can be released into the environment by various natural processes; however, mercury pollution has been significantly amplified by human activities such as mining, production of fertilizers, waste incineration and disposal.

  5. 4. Towards Abatement of Selected Emissions from Metals Manufacturing

    Författare :Diana Orrling; Seshadri Seetharaman; S. Subramanian; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mercury; zinc; iron; copper; sulfur dioxide; adsorption; pollution; spectroscopy; thermal desorption; polycrystalline; surfaces; Materials science; 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

  7. 5. Contamination in Swedich waste wood : environmental implications, sources and waste management strategies

    Författare :Joakim Krook; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Today, bulk materials, e.g. wood, plastic, steel, and concrete, are contaminated by hazardous substances such as heavy metals, causing environmental and resource problems during waste management. LÄS MER
