  1. 1. Long-term Effect of Metallic Iron Sorbents on Arsenic Mobility in an Anoxic Aquifer : An assessment based on long-term column experiments

    University essay from SLU/Dept. of Soil and Environment

    Author : Stéphanie Nyström; [2022]
    Keywords : Zero valent iron; ZVI; Remediation; Anoxic; Column tests; ICP-MS;

    Abstract : Zero valent iron (ZVI) sorbents have successfully remediated soils burdened with different groups of contaminants. When working to alleviate arsenic (As) contamination, the location-specific subsurface chemistry greatly affects the efficiency of the sorbents as it controls the speciation of As and the transformation of the ZVI, as well as the interaction between these (remediating mechanisms).

  3. 2. Stabilisation of arsenic in contaminated soil using iron distributed by electricity

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

    Author : Kajsa Engström; [2021]
    Keywords : Chemical stabilisation; soil remediation; contaminated soil; in situ pilot scale; sacrificial iron;

    Abstract : In Boden, northern part of Sweden, there is a site called Solgårdarna which has been used for wood impregnation. The activities on the site have led to soil contamination with chrome (Cr), copper (Cu) and arsenic (As), where the arsenic contamination is the most problematic. READ MORE

  4. 3. Solubility of arsenic in Swedish contaminated soils : experiments and modelling

    University essay from SLU/Dept. of Soil and Environment

    Author : Ann-Sophie Heldele; [2016]
    Keywords : arsenic; leaching; pH influence; geochemical modelling; contamination;

    Abstract : Even though arsenic can be found everywhere in the environment, it is phytotoxic and hazardous to human and animal health. Especially arsenic leaching produces contamination of groundwater. READ MORE

  5. 4. Fuktkvotens inverkan på oljeupptag och pigmentinträngning i tall (Pinus sylvestris L.) och gran (Picea abies L. Karst) vid impregnering med Linotechmetoden

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Anna Sjöström; [2008]
    Keywords : vattenavstötning; infärgning; linolja; trämaterial;

    Abstract : Wood has always been an important material for people, and it is used for many applications. As for example, fuel for cooking and heating houses, construction materials and for constructing means of transport. READ MORE

  6. 5. Phytoremediation of a highly creosote-contaminated soil by means of Salix viminalis

    University essay from SLU/Dept. of Soil Sciences

    Author : Karin Önneby; [2005]
    Keywords : wood impregnation site; phytoremediation; salix viminalis; PAH degredation; phenanthrene; anthracene; fluoranthene; pyrene; benzo[a]pyrene; GC-MS; bacterial strains; extracted and cultivable bacteria; bulk soil; rhizosphere soil;

    Abstract : The aims of this study were to investigate whether Salix viminalis could grow in a highly creosote contaminated soil and, if so, whether the introduction of the plant enhanced the dissipation of polycyclic aromatic hydrocarbons (PAHs). The purpose was also to examine whether inoculation of two different bacterial strains further enhanced the decrease of the contaminant. READ MORE
