  2. 1. Corrosion-included metal runoff from external constructions and its environmental interaction : a combined field and laboratory investigation of Zn, Cu, Cr and Ni for risk assessment

    Author : Sofia Bertling; Inger Odnevall Wallinder; Herbert E. Allen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Atmospheric corrosion; metal runoff; metal dispersion; soil; limestone; retention; Miljöteknik; Environmental engineering; Miljöteknik;

    Abstract : The 1990s has seen an increased awareness of possible environmental effects of corrosion-induced metal release from outdoor constructions. Considerable efforts have been initiated to perform critical assessments of possible risks of selected metals. Gaps of knowledge have been identified and research investigations started. READ MORE

  4. 2. Long-term metal retention processes in a peat bog : Field studies, data and modelling

    Author : Kristina Syrovetnik; Ivars Neretnieks; Bert Allard; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Peat; heavy metals distribution; sequential extraction; binding mechanisms; modelling; metal sulphide oxidation; aqueous composition; sorption; humic substances; ferric oxyhydroxide; Chemical engineering; Kemiteknik;

    Abstract : The study was inspired by the need to assess long-term metal retention in municipal solid waste (MSW) landfills. The long-term processes in landfills are poorly known due to the relatively short time that such landfills have been in existence. Natural analogues where similar metal binding processes could be expected were therefore sought for. READ MORE

  6. 4. Metal accumulation by plants : evaluation of the use of plants in stormwater treatment

    Author : Åsa Fritioff; Maria Greger; Lena Kautsky; Bert Wolterbeek; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Elodea canadensis; Potamogeton natans; uptake; translocation; distribution; toxicity; salinity; temperature; and leakage; Plant physiology; Växtfysiologi;

    Abstract : Metal contaminated stormwater, i.e. surface runoff in urban areas, can be treated in percolation systems, ponds, or wetlands to prevent the release of metals into receiving waters. Plants in such systems can, for example, attenuate water flow, bind sediment, and directly accumulate metals. READ MORE

  7. 5. Metal retention from leachate using Industrial Waste Products

    Author : Emma Nehrenheim; Sylvia Waara; Hanna Obarska-Pemplowiak; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental engineering; Miljöteknik; Energi- och miljöteknik;

    Abstract : Landfill leachate arises when water percolates through a landfill. The degree and type of pollution is dependent on the content of the landfill but also on a range of other factors, including the age of the landfill and the landfilling technique. READ MORE
