  1. 1. Chlorine Transport in a Small Catchment

    Författare :Teresia Svensson; Gunilla Öberg; Katarina Abrahamsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; catchment; chloride; chlorine; chloroform; organic chlorine; runoff water; soil; VOCls; avrinningsområde; avrinningsvatten; flyktiga klorerade föreningar klor; klorid; kloroform; organiskt klor; mark; Water in nature and society; Vatten i natur och samhälle;

    Sammanfattning : De senaste decenniernas forskning har påvisat att en omfattande bildning och nedbrytning av klororganiska föreningar sker i mark. Bildning av sådana föreningar sker genom att klorid binds in i organiskt material. LÄS MER

  3. 2. Chlorine Cycling in Terrestrial Environments

    Författare :Malin Montelius; David Bastviken; Teresia Svensson; Katarina Abrahamsson; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chloride; organic chlorine; chlorination; dechlorination; 36Cl; risk assessment modelling; Klorid; organiskt klor; klorering; deklorering; klor-36; riskmodellering;

    Sammanfattning : Chlorinated organic compounds (Clorg) are produced naturally in soil. Formation and degradation of Clorg affect the chlorine (Cl) cycling in terrestrial environments and chlorine can be retained or released from soil. LÄS MER

  4. 3. The chemistry of organic iodides under severe nuclear accident conditions in LWRs

    Författare :Sabrina Tietze; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic iodides; Wet-filter system scrubber ; Chlorine; Volatile iodine source term; Severe nuclear accident; Cables; Sorption; Containment; Paint; Iodine; LWR; Radiolysis;

    Sammanfattning : For many countries nuclear fission is an important part of their energy portfolio. However, a great concern is the occurrence of nuclear reactor accidents, which can result in the emission of radioactivity into the environment. LÄS MER

  5. 4. Organic chlorine and chloride in soil

    Författare :Emma Johansson; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Chloride is generally believed to be conservative with respect to water and is often used as atracer of water movement in hydrological research and biogeochemical modeling. However,the last decade of research has shown that naturally fanned organically bound chlorine isubiquitous in the environment. LÄS MER

  7. 5. Dioxins and dioxin-like compounds in thermochemical conversion of biomass : formation, distribution and fingerprints

    Författare :Qiuju Gao; Stina Jansson; Bogdan Dlugogorski; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polychlorinated dibenzo-p-dioxins; polychlorinated dibenzofurans; polychlorinated naphthalenes; PCDD; PCDF; PCN; persistent organic pollutants; torrefaction; pyrolysis;

    Sammanfattning : In the transition to a sustainable energy supply there is an increasing need to use biomass for replacement of fossil fuel. A key challenge is to utilize biomass conversion technologies in an environmentally sound manner. LÄS MER
