  1. 1. Management and Treatment of Organotin and Metal Contaminated Dredged Sediment

    Author : Anna Norén; Chalmers University of Technology; []
    Keywords : metals; tributyltin TBT ; life cycle assessment LCA ; multicriteria analysis MCA ; stabilization and solidification S S ; copper Cu ; electrolysis; dredged sediment; Fenton’s reagent; zinc Zn ;

    Abstract : Modern society is dependent on international trade and most traded goods are transported by sea. To enable this, regular dredging must be done to maintain water depth in ports and waterways, resulting in large quantities of often contaminated sediment that must be handled. READ MORE

    Abstract : Dredging activities at ports and harbors are inevitable for safe navigation of ships and vessels. The outcomes of dredging are huge volumes of dredged materials, which can range from very fine and contaminated sediments to sands and gravels. The coarse sands and gravels can be directly used in civil engineering applications. READ MORE

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

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

    Abstract : 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. READ MORE

  4. 4. Polychlorinated biphenyls (PCB) in a river ecosystem

    Author : Gudrun Bremle; Biologiska institutionen; []

    Abstract : Atmospheric deposition is one source of persistent pollutants such as polychlorinated biphenyls (PCB) in aquatic environments. Other point sources can also contribute to the PCB loadings in the water. READ MORE

  5. 5. Multielement Urban Geochemistry : Exporing the Expected, the Unexpected and the Unknown

    Author : Pasi Peltola; Mats Åström; Högskolan i Kalmar; []

    Abstract : Urban areas are hot-spots for the human use of most elements. These elements are the building blocks of our various goods and chemicals and are used both purposely and in a more unaware fashion. There are many ways in which the elements get dispersed from the human use. Commonly acknowledged and evident processes of dispersion are point sources (e. READ MORE
