  1. 1. Floating treatment wetlands for stormwater management : Plant species selection and influence of external factors for heavy metal and chloride removal in a cold climate

    Författare :Maria Schück; Maria Greger; Hans Brix; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Floating treatment wetlands; Phytodesalination; Rhizofiltration; Phytoremediation; Stormwater; Heavy metals; Chloride; Plant traits; Carex riparia; Carex pseudocyperus; Phalaris arundinacea; Flytande våtmarker; dagvatten; tungmetaller; klorid; fytoremediering; slokstarr; rörflen; jättestarr; växtfysiologi; Plant Physiology;

    Sammanfattning : Stormwater, which consists of rainwater and snowmelt, often contains pollutants from vehicle traffic, building materials, and industries. These pollutants include chloride and heavy metals, which can cause several environmental issues, such as being toxic to biota at elevated concentrations. LÄS MER

  3. 2. 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

  4. 3. 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

  5. 4. DFT calculations of initial localized corrosion of aluminum : Influence of aqueous ad-layer, chloride ions, and intermetallic particles

    Författare :Min Liu; Jinshan Pan; Ying Chen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aluminum alloys; alumina; chloride; surface adsorption; aqueous ad-layer; localized corrosion; corrosion initiation; work function; micro-galvanic effect; density-functional theory; Volta potential; scanning kelvin probe force microscopy; Kemi; Chemistry;

    Sammanfattning : Localized corrosion of aluminum (Al, here including Al alloys) involves a series of physico-chemical processes at the interface between the metal and the aqueous ad-layer or the aqueous solution. The mechanisms that govern localized corrosion are quite complex and have been the subject of many experimental studies. LÄS MER

  7. 5. Heavy metal removal by floating treatment wetlands: Plant selection

    Författare :Maria Schück; Maria Greger; Åsa Danielsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phytoremediation; Rhizofiltration; Heavy metal; Chloride; Floating treatment wetland; Wetland plants; Stormwater; Plant Physiology; växtfysiologi;

    Sammanfattning : Elevated levels of heavy metals and chloride are commonly found in stormwater, as a consequence of pollution from traffic, building material and industries, and the use of salt for deicing in wintertime. Floating treatment wetlands (FTWs), consisting of vegetated rafts that can be placed in stormwater ponds, may be able to reduce heavy metal and chloride concentrations, but until this date have mainly been used for nutrient removal in warm climates.
