  1. 1. In situ electrokinetic remediation of soil co-contaminated with trace elements and polycyclic aromatic hydrocarbons

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Emma Heidrich; [2023]
    Keywords : polycyclic aromatic hydrocarbons; trace elements; co-contaminated soil; electrokinetic remediation; iron electrodes;

    Abstract : Sites contaminated with polycyclic aromatic hydrocarbons can be simultaneously contaminated with trace elements. Co-contaminated soil is considered a complex problem since inorganic and organic contaminants behave differently and thereby often require different remediation strategies. READ MORE

  3. 2. Newly inundated forest landscapes - hotspots for mercury in water and benthic fauna

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Kirstine Evald Andersson; [2023]
    Keywords : Wetland restoration; Inundation; Mercury cycling; Beaver impoundments; Aquatic biogeochemis-try;

    Abstract : Mercury (Hg) is a widespread contaminant in high-latitude aquatic ecosystems, where it can undergo microbial transfor-mation into toxic methylmercury (MeHg). Due to its chemical properties, MeHg tends to accumulate in the aquatic food chain and will eventually end up in predatory species at the top of the terrestrial food web. READ MORE

    Abstract : Dricksvatten är en essentiell del av ett hållbart samhälle. Därför är det viktigt att säkerställa säkert dricksvatten genom fungerande vattenreningsverk. En viktig förorening att behandla är NOM, som i sig är ofarligt men som kan producera farliga föroreningar. En teknik som används för behandling av NOM är kolfiltrering. READ MORE
