  1. 1. Urban heavy metals : Stocks and flows

    University dissertation from Linköping : Linköping University

    Author : Louise Sörme; Linköpings universitet.; Linköpings universitet.; [2003]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Heavy metais; urban areas; Substance flow analysis; inflow; stock; outflow; diffuse emisson; waste; wastewater treatment plant; legislation; Tungmetaller; miljöaspekter; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Levels of heavy metals in different media are high today, both in Stockholm and other urban areas. Where do the metals come from? Production emissions and point sources are not the answer, since earlier research has shown that production emissions are lower than emission from goods during use (the diffuse emission). READ MORE

  2. 2. Modelling of Substance Flows in Urban Drainage Systems

    University dissertation from Linköping : Linköping University

    Author : Stefan Ahlman; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; urban stormwater; source control; modelling; diffuse pollution; BMPs;

    Abstract : 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. READ MORE

  3. 3. Environmental System Analysis of Waste Management Experiences from Applications of the ORWARE Model

  5. 5. Flow-oriented studies for environmental management by local authorities : experiences from a regional substance flow analysis

    University dissertation from Linköping : Linköpings universitet

    Author : Annica Lindqvist-Östblom; Linköpings universitet.; Linköpings universitet.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow-oriented studies; material flow analysis; substance flow analysis; interpretation; local authorities; regional authorities; environmental management; cadmium; sewage;

    Abstract : This thesis focuses on the issue of how to perform flow-oriented studies in order to become more useful for and adapted to local/regional authorities. Compared to traditional environmental monitoring and measurement of the state of the environment, flow-oriented studies are an attempt to broaden the approach to environmental concerns. READ MORE
