    University essay from SLU/School for Forest Management

    Author : Karoline Åby Hedenius; [2016]
    Keywords : trädföryngring; brandintensitet; ekopark;

    Abstract : Fire has been a natural disturbance in boreal forests for a very long time. Species in the forest have evolved and adapted themselves to this disturbance. During the 1900th century big natural forest fires started to decrease because of human suppression and environments created by wildfire in the forest have now become rare. READ MORE

  3. 22. Per- and polyfluoroalkyl substances (PFASs) in Swedish waters

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Johanna Hedlund; [2016]
    Keywords : per- and polyfluoroalkyl substances; PFAS; fire training; firefighting foam; landfill; leachate; groundwater; surface water; effluent; drinking water;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) is a group of persistent, bioaccumulative and toxic pollutants. PFASs are widely used in industrial processes and products such as water- and fat repelling surfaces in clothes, paints and paper. They are also used in certain types of firefighting foams and have been found in ski waxes. READ MORE

  4. 23. Mass flows of per- and polyfluoroalkyl substances (PFASs) in a Swedish wastewater network and treatment plant

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Linda Glimstedt; [2016]
    Keywords : per- and polyfluoroalkyl substances; PFAS; 6:2 FTSA; wastewater; wastewater network; wastewater treatment; WWTP; Uppsala; Kungsängsverket; per- och polyfluoroalkylerade substanser; PFAS; 6:2 FTSA; avloppsvatten; ledningsnät; avloppsnät; avloppsvattenrening; reningsverk; Uppsala; Kungsängsverket;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are man-made substances that hold unique properties. They are not only oil- and water repellants but also very resistant to degradation. Due to these properties, the applications are endless and PFASs can be found in a wide range of industrial applications and commercial products. READ MORE

  5. 24. Regeneration dynamics of pedunculate oak in natural temperate forests: a case from southern Sweden

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Olle Finnström; [2016]
    Keywords : eutrophic temperate mixed broadleaf forest; competition; crown size; disturbance; oak regeneration; pedunculate oak; quercus robur; stem diameter; tree height;

    Abstract : Oaks are some of the most wide-spread and iconic trees in human culture, yet populations of oaks are declining due to land conversion, disease and because of lack of disturbance in temperate forests. Oaks are fairly light demanding trees, requiring large-scale disturbance to create suitable environments for regeneration. READ MORE

  6. 25. Uptake of per- and polyfluoroalkyl substances by plants

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Laura Gobelius; [2016]
    Keywords : phytoremediation; Arlanda Airport; PFASs; groundwater; soil; plant; AFFF; aqueous fire fighting foams;

    Abstract : The extensive use of per- and polyfluoroalkyl substances (PFASs) as surfactants in, for example textiles,cookware and aqueous firefighting foams (AFFFs) during the last decades has resulted in widespread environmental contamination. Due to the persistent and bioaccumulative characteristics of PFASs, they are ubiquitously found in the environment, wildlife and humans. READ MORE
