  1. 21. Stabilisation of arsenic in contaminated soil using iron distributed by electricity

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

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

    Sammanfattning : 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. LÄS MER

  3. 22. Remediation of an arsenic-contaminated anoxic aquifer in hjältevad with zerovalent iron : assessment and modelling of sorption strength and solubility of arsenic

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Kathrin Leicht; [2021]
    Nyckelord :arsenic remediation; zerovalent iron; anoxic aquifer;

    Sammanfattning : In-situ injection of zerovalent Iron (ZVI) particles to remediate contaminated groundwater is a widely applied approach. However, studies assessing the remediation and immobilisation mechanisms of Arsenic (As) under anoxic field conditions with zerovalent iron particles are lacking, especially for nanosized sulphidated ZVI (S-nZVI) and oxidic shell free ZVI (OSF-nZVI).

  4. 23. Contamination analysis of the landfill Rösaberg inerta massor : Risk assessment and investigation of the contaminant distribution

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Westander Lisa; [2020]
    Nyckelord :Landfill; MODFLOW; Risk assessment; Site-specific guidelines; Deponi; MODFLOW; Riskbedömning; Platsspecifika riktvärden;

    Sammanfattning : The dispersion of contaminants deriving from landfills poses a risk to the surrounding environment and human health. Old landfills are treated with extra precaution, due to their poorer construction, less stringent operation and lack information regarding the waste content. Vetlanda municipality has identified 48 old landfills. LÄS MER

  5. 24. Evaluation of the possibility of phytoremediation (using Salix) as a management tool for abandoned sites moderately contaminated with arsenic : a literature review

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Victor Akinwale; [2020]
    Nyckelord :phytostabilization; leaching; solubility and mobility; economic benefits;

    Sammanfattning : The presence of arsenic in soil and water has become an increasing problem in many countries around the world. The exposure of high concentration of arsenic in its inorganic form in natural environment such as soil and water makes it harmful to both humans, wildlife and plants. LÄS MER

  7. 25. Klimatanpassa marksanering : Förbättringsförslag för ökad tillämpning av biologiska marksaneringsmetoder

    Kandidat-uppsats, Jönköping University/JTH, Byggnadsteknik och belysningsvetenskap

    Sammanfattning : Purpose: In Sweden, there are area that are polluted and in need of remediation. However, soil remediation processes have a negative secondary impact on the climate. There are various soil remediation methods to apply, of which dig and dump are the most frequently used. The method involves although high emissions of carbon dioxide. LÄS MER
