1. 11. 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. 12. Environmental actions on concrete exposed in marine and road environments and its response - Consequences for the initiation of chloride induced reinforcement corrosion

   Författare :Anders Lindvall; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; corrosion; de-icing salt; road conditions; marine conditions; service life predictions; reinforcement; chloride; concrete; moisture conditions; environmental actions;

   Sammanfattning : The object of the study presented here has been to describe, further explain and model the influence of the exposure conditions on reinforced concrete structures and the consequences on their expected service life. The focus has been on investigating and quantifying the exposure conditions for structures in marine and road conditions exposed to chloride ions. LÄS MER

4. 13. Chloride transport and inflammation in cystic fibrosis airways

   Författare :Georgia Varelogianni; Godfried Roomans; Marie Johannesson; Ólafur Baldersson; Örebro universitet; []
   Nyckelord :Cystic fibrosis; CFTR; chloride efflux; N-acetylcysteine; ambroxol; duramycin; Nod-like receptors; cytokines; Medicin; Medicine;

   Sammanfattning : Cystic fibrosis (CF) is one of the most common lethal, autosomal recessive inherited diseases among Caucasians. It is caused by a mutation in the cystic fibrosis transmembrane conductance regulator (CFTR), a chloride channel activated by cyclic AMP. LÄS MER

5. 14. EstimatingChloride concentration in surface water and groundwater duet to deicing salt application

   Författare :Eva-Lotta Thunqvist; KTH; []
   Nyckelord :road; deicing salt; monitoring; chloride; catchment area; river basin; simulation; GIS; groundwater; surface water;

   Sammanfattning : A road in operation along with its traffic can pose aserious pollutant threat to groundwater and surface water inits vicinity. Examples of pollutants are metals from thecorrosion of vehicles, rails and poles and the wear of roadsurfaces and tyres; hydrocarbons from the wear of roadsurfaces, tyres, exhausts, oils; sodium chloride from roadsalt; and hazardous goods discharged in accidents.

7. 15. 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.
