  1. 11. Physical process effects on catchment-scale pollutant transport-attenuation, coastal loading and abatement efficiency

    Författare :Georg Lindgren; Georgia Destouni; Roko Andricevic; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Efficient pollutant load abatement; groundwater-surface water interactions; biogeochemical cycles; nitrogen; Lagrangian stochastic travel time approach; GIS; Hydrology; Hydrologi;

    Sammanfattning : Pollutants follow various subsurface and surface water pathways from sources within a catchment to its outlet and may cause detrimental effects on downstream water quality and ecosystems. Along their different transport pathways through a catchment, pollutants may be attenuated subject to different physical and biogeochemical processes. LÄS MER

  3. 12. Pollutant profiles as tools for characterisation of environmental exposure

    Författare :Håkan Wingfors; Peter Haglund; Calle Nilsson; Georg Becher; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Multivariate; PCB; PAH; dioxin; PLS; Environment; road tunnel; Miljökemi; Environmental chemistry; Miljökemi; analytisk kemi; Analytical Chemistry;

    Sammanfattning : This thesis is concerned with measurements of persistent organic pollutants (POPs) in environmental samples. The POPs consist of several groups of compound with many isomers, hence analysing POPs in a complex environment is a This thesis is concerned with measurements of persistent organic pollutants (POPs) in environmental samples.

  4. 13. Coagulation process characteristics and pollutant removal from urban runoff

    Författare :Fredrik Nyström; Inga Herrmann; Annelie Hedström; Maria Viklander; Michael Cimbritz; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stormwater; urban snowmelt; road runoff; coagulation flocculation sedimentation; coagulation characteristics; coagulation mechanism; treatment efficiency; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

    Sammanfattning : Many different stormwater control measures (SCMs) can be implemented in order to mitigate issues with polluted stormwater flows into receiving water bodies.  The treatment function of  SCMs is commonly based on the removal of particles by sedimentation, thereby also removing pollutants associated with particles.
