  2. 1. Effects of fungi on the distribution of metals in soil systems

    Author : Tina Krantz-Rülcker; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Metaller; förorenande ämnen; Markföroreningar; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Fungal biomass has previously been shown to be an effective adsorbent for recovery of metals from heavily polluted wastes and waters. Most studies of metal accumulation properties by fungi have therefore been performed at high metal concentrations and using preconditioned fungal biomass. READ MORE

  5. 3. Automatic Reduction Procedures for Chemical Mechanisms in Reactive Systems

    Author : Terese Lövås; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mechanism Reduction; Combustion; Physics; Emissions; Fysik; Fysicumarkivet A:2002:Lövås;

    Abstract : To deal with complex physical and chemical processes in reactive systems, such as combustion processes, it is necessary to find methods that simplify modelling in such a way that it becomes both more comprehensible and practically useful. In the work reported here a method for automatically reducing chemical reaction mechanisms has been developed for use in computer simulations of various combustion systems. READ MORE

  6. 4. Environmental assessment of construction with recycled materials

    Author : Sofia Lidelöw; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Avfallsteknik; Waste Science and Technology;

    Abstract : The use of industrial residues as raw materials in construction raises concerns over the potential leaching and dispersal of hazardous constituents from them into the environment. Their leaching behaviour has been studied in laboratory assays, but leaching processes in the field over larger spatial and temporal scales are more complex due to variations in the conditions the materials are exposed to, and less well understood.

  7. 5. Advancing the Frontier of Extended Producer Responsibility: The management of waste electrical and electronic equipment in non-OECD countries

    Author : Panate Manomaivibool; Internationella miljöinstitutet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Extended Producer Responsibility EPR ; Waste Electrical and Electronic Equipment WEEE ; Electronic Waste E-waste ; Policy Transfer; Waste Policy; Product Policy; Recycling;

    Abstract : Waste electrical and electronic equipment (WEEE) has become a salient issue in non-OECD countries. With a growing awareness about serious damages to the environment and human health from a lack of safe treatment and recycling of WEEE, there has been a search for policy responses in several of these countries.
