1. 6. Stormwater bioretention: Pollutant occurrence and accumulation in filter materials and forebays

   Författare :Robert Furén; Godecke-Tobias Blecken; Jes Vollertsen; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioretention; Biofilter; storwater; quality; treatment; filter material; forebay; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

   Sammanfattning : Urban areas are affected by anthropogenic activities and produce pollutants that are transported to recipients and receiving waters during precipitation. Untreated stormwater runoff is a main driver of environmental degradation, and the interest in stormwater quality treatment has increased with the awareness of stormwater pollution. LÄS MER

4. 8. Contribution of stormwater ponds for road runoff to aquatic biodiversity

   Författare :Zhenhua Sun; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; road salt; stormwater ponds; water quality; sediments; road runoff; metals; pond size; aquatic biodiversity;

   Sammanfattning : The increased recognition that roads may impair the aquatic environment and ecosystems has led to a shift from conventional drainage systems toward blue-green solutions such as stormwater ponds. Research on blue-green stormwater solutions has until now mainly focused on water quantity and quality. LÄS MER

5. 9. The Ecological Role of Roadside Stormwater Ponds - Potential to Support Biodiversity

   Författare :Zhenhua Sun; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Macroinvertebrates; Stormwater ponds; DNA metabarcoding; Sediments; High throughput sequencing; Road runoff; Water quality; Aquatic biodiversity;

7. 10. Sources and fluxes of organic contaminants in urban runoff

   Författare :Karin Björklund; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; alkylphenols; substance flow analysis; sediment; concentrations in urban matrices; urban runoff quality predictions; source identification; phthalates; stormwater; snow;

   Sammanfattning : Urban runoff quality is recognized as one of the most significant pressures on aquatic ecosystems worldwide. Research into pollutants in urban runoff has traditionally focused on nutrients, suspended solids and metals and consequently knowledge of anthropogenic organic pollutants is limited. LÄS MER
