  1. 1. Transport of Mercury Species in the Environment. Exchange between Oceanic Waters and the Atmosphere

    Författare :Maria Andersson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mercury; dissolved gaseous mercury; elemental mercury; evasion; flux; Mediterranean Sea; North Atlantic Ocean; Arctic Ocean; accumulation; in-situ measurements; on-line measurements;

    Sammanfattning : Mercury is an element present in the earth crust as well as a component in the atmosphere. During centuries mercury has been released by natural sources, e.g. volcanic eruptions, evasion from water surfaces and degassing from soil. LÄS MER

  3. 2. Mercury accumulation in zoobenthos : an important mechanism for the transport of mercury from sediment to fish

    Författare :Helena Parkman; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : .... LÄS MER

  4. 3. Remediation of mercury polluted soil

    Författare :Thomas Lifvergren; Bert Allard; Örebro universitet; []
    Nyckelord :soil pollution; soil remediaion; mercury; NATURAL SCIENCES; NATURVETENSKAP; Enviromental Science; Miljövetenskap;

    Sammanfattning : Mercury in contaminated soil constitutes a wide spectrum of species with highly different properties due to the chemical complexity of the element. Assessments of risk, ecological effects and removal potential require process and mobility studies. LÄS MER

  5. 4. 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

  7. 5. Mercury cycling in the global marine environment

    Författare :Michelle Nerentorp; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; sea ice; air; seasonal and spatial variation; snow; Mercury cycling; seawater; mercury flux;

    Sammanfattning : Mercury is a globally distributed contaminant that exists in the atmosphere in its elemental form as a stable monoatomic gas. Having a residence time of around one year in air allows it to be transported far from emission sources and end up in polar ecosystems. LÄS MER
