  2. 21. Investigating the Relation between Efficient, Effective and Sustainable Remediation of Contaminated Sites

    Author : Robert Anderson; Chalmers tekniska högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; effective remediation; multi-criteria decision analysis; efficient remediation; decision support; sustainability assessment; cost-benefit analysis; contaminated sites;

    Abstract : Remediation of contaminated sites reduces negative impacts to humans and the environment, but the process itself is typically associated with high costs to society and large environmental footprints. The sustainable remediation concept has, over the past decade, brought increased attention to the often-overlooked contradictory effects of site remediation. READ MORE

  4. 22. 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 : 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;

    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

  5. 23. Organic Phosphorus Compounds in Aquatic Sediments : Analysis, Abundance and Effects

    Author : Joakim Ahlgren; Emil Rydin; Monica Waldebäck; Lars Tranvik; Karin Markides; Sven Blomqvist; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Organic phosphorus; aquatic sediment; eutrophication; NMR; internal loading; sample preparation; extraction; degradation; Miljökemi; Environmental chemistry; Miljökemi;

    Abstract : Phosphorus (P) is often the limiting nutrient in lacustrine and brackish eco-systems, and enhanced input of P into an aquatic system might therefore negatively impact the environment. Because modern waste water manage-ment have reduced external P input to surface waters, internal P loading from the sediment has become one of the main P sources to aquatic ecosys-tems, in which relatively unknown organic P compounds seem to be more active in P recycling than previously thought.

  6. 24. Assessing Soil Functions for Sustainable Remediation of Contaminated Sites

    Author : Yevheniya Volchko; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; soil ecosystem services; Contaminated sites soil; minimum data set; remediation; sustainability assessment; soil quality indicators; soil functions;

    Abstract : Soil contamination is a worldwide problem. Soil remediation is often carried out to reduce the risks posed by contaminants in the soil to human health and environment. Contaminant concentration is typically the only soil quality aspect maintained in remediation projects. READ MORE

  7. 25. Remediation of PFAS-contaminated soil and wastewater : Feasibility of chain treatment applying destructive techniques

    Author : Jean Noel Uwayezu; Ivan Carabante; Jurate Kumpiene; Anett Georgi; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Avfallsteknik; Waste Science and Technology;

    Abstract : Per- and polyfluoroalkyl substances (PFAS) are man-made chemicals ubiquitously distributed in soil and aquatic media, resulting from their wide range of industrial applications. Today, PFAS is a global concern due to their persistence in the environment and their adverse effects on humans and the ecosystem. READ MORE
