  1. 1. Biogenic Halocarbons in Polar Sea Ice

    Författare :Anna Granfors; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Volatile biogenic halocarbons; Sea ice; Antarctica; ice-air flux; gases;

    Sammanfattning : Sea ice is to date a rather poorly investigated part of the cycling of volatile halogenated organic compounds, halocarbons. These compounds are natural sources of reactive iodine and bromine to the atmosphere, and are produced in the marine environment. LÄS MER

  3. 2. On Biogenic Halocarbons in Antarctic Waters

    Författare :Erik Mattsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Volatile biogenic halocarbons; Antarctica; Southern Ocean; Sea ice; Snow; Air-sea exchange;

    Sammanfattning : Little is known regarding the distribution of naturally produced volatile halogenated organic compounds, halocarbons, in Antarctic waters and the contribution of these waters to the global atmospheric load of halogens. In the atmosphere, halocarbons are degraded by photolysis, and form reactive halogen radicals. LÄS MER

  4. 3. Lättflyktiga halokarboner : miljöeffekter och ersättningsalternativ i industrielle processer och produkter

    Författare :Tomas Rydberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water-based; CFC-alternative; halocarbons; release agent; ozone-layer; clean technology; phase-out;

  5. 4. Formation and Distribution of Marine Biogenic Halocarbons with Emphasis on Polar Regions

    Författare :Anders Karlsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; volatile biogenic halocarbons; Arctic Ocean; Southern Ocean; sea ice; snow; air-sea exchange; cyanobacteria;

    Sammanfattning : It is well-established that marine micro- and macroalgae form volatile halogenated compounds (halocarbons). Production occurs throughout the world ocean with strong regional sources in coastal areas. In the atmosphere, these compounds are converted to reactive inorganic halogen compounds, which degrade ozone. LÄS MER

  7. 5. Production of hydrogen peroxide and volatile halocarbons by macroalgae

    Författare :Jonas Collén; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;
