  2. 1. Chlorine Transport in a Small Catchment

    Author : Teresia Svensson; Gunilla Öberg; Katarina Abrahamsson; Linköpings universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 3. Chlorine Cycling in Terrestrial Environments

    Author : Malin Montelius; David Bastviken; Teresia Svensson; Katarina Abrahamsson; Linköpings universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Compound-specific stable chlorine isotope analysis : A versatile tool for investigating biochemical and geochemical processes of organochlorine substances

    Author : Henry Holmstrand; Per Andersson; Örjan Gustafsson; Neil Sturchio; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; compound-specific chlorine isotope analysis; chlorinated organic compounds; Environmental chemistry; Miljökemi;

    Abstract : Chlorinated organic compounds (OCls) from anthropogenic sources are generally considered to be a class of chemicals with high potential for ecotoxicity, including infamous substances such as polychlorinated biphenyls (PCB), dichloro-dibenzo-trichloroethane (DDT) and polychlorinated dibenzo-p-dioxins (PCDD). OCls are also produced naturally, sometimes at the same order of magnitude as anthropogenic compounds. READ MORE

  7. 5. Organic chlorine and chloride in soil

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

    Abstract : 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. READ MORE
