  1. 21. Microbial bioremediation and characterization of Arsenic resistant bacteria

    Magister-uppsats,

    Författare :Aminur Rahman; [2011]
    Nyckelord :;

    Sammanfattning : Arsenic is a toxic metalloid existing everywhere in the nature. It is toxic to most organisms and considered as human carcinogen. Arsenic contamination leads to severe health problems with diseases like damage of skin, lung, bladder, liver and kidney as well as central nervous system. LÄS MER

  3. 22. The potential of biodegradation on 1, 1, 1-trichloro-2, 2-bis (p-chlorophenyl) ethane, based upon co-metabolism of indigenous bacteria

    Master-uppsats, Akademin för hållbar samhälls- och teknikutveckling

    Författare :Aniko Hellebrandt; [2010]
    Nyckelord :soil contamination; DDT; Ostracodtoxkit FTM; biodegradation; bioreactors; talaj szennyezés; DDT; Ostracodtoxkit FTM; biodegradáció; bioreaktorok;

    Sammanfattning : The purpose of this project is to evaluate the potential of a bioreactor system to degrade DDT based upon co-metabolism of indigenous bacteria. The study was performed with soil samples spiked with four different concentrations of DDT. LÄS MER

  4. 23. Anaerob nedbrytning av TNT : Ett bioreaktorförsök på Vingåkersverken

    Master-uppsats, Akademin för hållbar samhälls- och teknikutveckling

    Författare :Johan Lindmark; [2008]
    Nyckelord :TNT; Bioreaktor; anaerob; slurry; BIOREX;

    Sammanfattning : A bioslurry reactor was built for the bioremediation of TNT contaminated waste from the demilitarization industry. The field test was conducted at Vingåkersverken in Vingåker, Sweden, to see if results from laboratory studies could be repeated in a full scale reactor. LÄS MER

  5. 24. Degradation of aged creosote and diesel contaminated soils by phytoremediation or biostimulation (nutrients)

    L3-uppsats, SLU/Dept. of Soil Sciences

    Författare :Nghia Nguyen Khoi; [2007]
    Nyckelord :creosote; diesel fuel; PAHs; benzo fluoranthene; benzo pyrene; phenathrene; bioremediation; phytoremediation; salix clones;

    Sammanfattning : Aged creosote and diesel fuel polluted soil was collected from Resecentrum, Uppsala (deposited at Hovgården). The aims of this study were: 1) to compare the growth and degradation of PAHs and diesel by five Salix clones and 2) to study the effect of nutrients on biodegradation of PAHs and diesel. LÄS MER

  7. 25. Environmental Impacts of Contaminated Site Remediation : a Comparision of two Life Cycle Assessments

    Magister-uppsats, Institutionen för tematisk utbildning och forskning

    Författare :Jenny Andersson; [2003]
    Nyckelord :Interdisciplinary studies; Contaminated site; remediation; life cycle assessment; bioremediation; adsorption; environmental impact; decision support tool; TVÄRVETENSKAP;

    Sammanfattning : The decision process of which technique to choose for remediation of contaminated sites has traditionally focused on the clean up level, the time required and the economical resources. The environmental costs of the remediation are seldom taken into consideration. LÄS MER
