  1. 11. Polychlorinated biphenyls (PCB) in a river ecosystem

    Författare :Gudrun Bremle; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrobiology; dredging; landfill; cleanup; remedial action; air; fish; sediment; Persistent organic pollutants; freshwater; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

    Sammanfattning : 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. LÄS MER

  3. 12. Solid Waste Landfills in an Arid Environment : Site Selection and Design

    Författare :Ali Chabuk; Jan Laue; Nadhir Al-Ansari; Sven Knutsson; Hussain M. Hussain; Roland Pusch; Rafid Alkhaddar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Landfill; Arid Environment; Site selection; Design; Babylon; Iraq; Soil Mechanics; Geoteknik;

    Sammanfattning : Selecting landfill sites is considered a complicated task because its whole process is based upon several factors and restrictions. This study shows the present status of solid waste management, sources, collection personnel, machinery and equipment that are involved in the waste collection process, financing and financial management for the major cities of the Babylon Governorate in Iraq (Al-Hillah, Al-Qasim, Al-Mahawil, Al-Hashimiyah and Al-Musayiab).

  4. 13. Generation of Leachate and the Flow Regime in Landfills

    Författare :David Bendz; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; Hydrogeologi; geographical and geological engineering; Hydrogeology; model; transport; flow; leachate; water; hydrology; landfill; MSW; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Sammanfattning : The environmental impacts of landfills are associated mainly with the emission of leachate and biogas. Sanitary landfilling aims to stabilize the landfill in a efficient and controlled way, so that the environmental impacts are minimized. When a sanitary landfill has attained its final storage quality, it can be integrated into the environment. LÄS MER

  5. 14. Biogas generation in landfills : equilibria, rates & yields

    Författare :Mattias Åkesson; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; model; limitation; volatile fatty acids; kinetics; biogas; thermodynamics; methane; Landfill; test cell; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Sammanfattning : Landfilling in "cells" has become more common in recent years. Different waste streams are guided to different cells, among which the biocell is a landfill designed for biogas production. In this thesis, the dependence of biogas generation on waste composition was investigated. LÄS MER
