  1. 1. Dynamics of water pollution control : A regional evaluation

    Författare :Marianne Löwgren; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The 1970's saw a strong governmental backing of measures taken to improve surface water quality by reducing point-source emissions in Sweden. The aim of this thesis primarily was to evaluate the cost effectiveness of governmental strategies implemented to improve surface water quality and to study the relationship between policies adopted and current knowledge about different sources of pollution.

  3. 2. Nonpoint source water pollution management : Monitoring, assessment and wetland treatment

    Författare :Lorin Reinelt; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The management of nonpoint (diffuse) sources of-water pollution has received increased attention during the past decade. New techniques that aid in the identification and assessment of these diffuse sources can increase the chances for success of nonpoint source control efforts. LÄS MER

  4. 3. Modelling of Substance Flows in Urban Drainage Systems

    Författare :Stefan Ahlman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; urban stormwater; source control; modelling; diffuse pollution; BMPs;

    Sammanfattning : Stormwater is recognised as a large contributor of toxic substances to receiving waters. Different measures to manage stormwater quality have been proposed, including structural and non-structural best management practices (BMPs). Computer models have become useful tools for the analysis, evaluation and design of these BMPs. LÄS MER

  5. 4. Tracing Copper from society to the aquatic environment : Model development and case studies in Stockholm

    Författare :Qing Cui; Maria E. Malmström; Olle Wahlberg; KTH; []
    Nyckelord :diffuse source; source analysis; sediment pollution levels; urban lake; Copper; Stockholm archipelago; SFA; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Copper remains at elevated levels in the aquatic environment of Stockholm due to diffuse urban sources. Management of these diffuse sources requires their quantification but they cannot be measured directly by field observations. LÄS MER

  7. 5. Sources and fate of plastic particles in northern European coastal waters

    Författare :Therese Karlsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plastic pollution; microplastics; method development; polyethylene; FTIR spectroscopy;

    Sammanfattning : Plastics are integral parts of our lives and have allowed for important technological leaps within society. However, an unwanted consequence of our current consumption of plas-tics is marine plastic pollution and in order to reduce its impact we need to understand its sources and fate patterns. LÄS MER
