  1. 16. A Deep Dive into Sediments : Exploring approaches to assess environmental risks and achieving environmental goals in management of contaminated sediments in Sweden

    Författare :Peter Bruce; Clare Bradshaw; Yvonne Ohlsson; Anna Sobek; Sabine Apitz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sediment; risk assessment; risk evaluation; risk management; contaminants; regulations; weight of evidence; line of evidence; environmental goals; environmental management; guidelines; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : Contaminated sediments are common, especially near urban and industrialized areas, and they can have negative ecological effects. In three studies, I explore the challenges for environmental management of contaminated sediments, focusing on environmental risk assessment (ERA) in Sweden. LÄS MER

  3. 17. Treatment methods for the removal of per- and polyfluoroalkyl substances (PFASs) from drinking water : optimizing existing and exploring novel treatment techniques

    Författare :Vera Franke; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Worldwide, the demand for safe drinking water is rising. As drinking water sources are increasingly impacted by anthropogenic and environmental changes it is becoming a challenge to produce safe and clean water. LÄS MER

  4. 18. Environmental Assessments of Landscape Changes : Interdisciplinary studies in rural Tanzania

    Författare :Louise Simonsson; Lennart Strömquist; Annika Dahlberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geography; Environmental assessment; interdisciplinary methodology; landscape; perceptions; preferences; land; forest; miombo woodlands; resources; biodiversity; Tanzania; Geografi; Other earth sciences; Övrig geovetenskap;

    Sammanfattning : This thesis aims to show how biogeophysical and social processes are interlinked in landscape change, and to propose approaches for interdisciplinary environmental assessments (such as EIAs), concentrating on developing countries’ situations, and representation of findings from such studies. Landscape in its holistic sense is a very good concept and basis for intellectual and practical use in environmental dialogues. LÄS MER

  5. 19. Corrosion-included metal runoff from external constructions and its environmental interaction : a combined field and laboratory investigation of Zn, Cu, Cr and Ni for risk assessment

    Författare :Sofia Bertling; Inger Odnevall Wallinder; Herbert E. Allen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Atmospheric corrosion; metal runoff; metal dispersion; soil; limestone; retention; Miljöteknik; Environmental engineering; Miljöteknik;

    Sammanfattning : The 1990s has seen an increased awareness of possible environmental effects of corrosion-induced metal release from outdoor constructions. Considerable efforts have been initiated to perform critical assessments of possible risks of selected metals. Gaps of knowledge have been identified and research investigations started. LÄS MER

  7. 20. Processes and factors governing benthic community dynamics—environmental change in the Baltic Sea

    Författare :Christian Sommer; Sara Sjöling; Patrik Dinnétz; Inger Porsch Hällström; Alexander Eiler; Södertörns högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Benthic communities; Baltic Sea; biodiversity; community composition; environmental change; environmental genomics; microbial ecology; Major Baltic Inflow; meta-population; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : As drivers of biogeochemical cycles and nutrient recycling, such as carbon turnover, the microbial community is essential in sustaining functioning ecosystems. Together with the metazoan community, the microbial community constitute the majority of all life in the benthos. LÄS MER
