  1. 1. Environmental aspects of coal mine drainage: a regional study of Moatize in Mozambique

    Författare :Estevao Pondja; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; coal mining; acid mine drainage; mine water treatment; climate change; low-cost adsorbent;

    Sammanfattning : Mozambique is one of the largest coal producers in Africa. Extraction of the coal is carried out in the Moatize district of the Tete province in the center of the country. A surface mining technique is used to extract the coal below ground level. LÄS MER

  2. 2. When bioelectrochemical systems meet extremophiles, possibilities and challenges

    Författare :Gaofeng Ni; Mark Dopson; Bert Hamelers; Linnéuniversitetet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acidophiles; psychrophiles; haloalkaliphiles; bioelectrochemical systems; microbial sulfur metabolism; 16S rRNA gene amplicon sequencing; metagenomics; metatranscriptomics; Mikrobiologi; Microbiology;

    Sammanfattning : Extremophiles are microorganisms live and thrive in extreme environments that are harsh and hostile to most forms of life on earth (e.g. low pH, low temperature, high pH and high salinity). They have developed strategies to obtain nutrients and conserve energy to sustain life under these adverse conditions. LÄS MER

  3. 3. Appropriate Technologies for Soil Remediation in Low Prioritized Region : Developing Countries and Sparsely Populated Regions

    Författare :Henrik Haller; Anders Jonsson; Morgan Fröling; Jaak Truu; Mittuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Soil pollution; Bioremediation; Ecotechnology; Framework for Strategic Sustainable Development; Ecological Engineering; Industrial Ecology Developing Countries; Sparsely Populated Regions; Nicaragua;

    Sammanfattning : Contaminated sites in low prioritized regions demand remediation technologies that are cost- and energy-effective and locally adapted. Parameters such as the time frame during which bioremediation degradation needs to occur may not be as restraining as in urban environments. LÄS MER

  4. 4. Remediation of materials with mixed contaminants : treatability, technology and final disposal

    Författare :Kristin Elgh-Dalgren; Patrick van Hees; Bert Allard; Dan Berggren Kleja; Örebro universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Bioremediation; Microtox®; mixed contaminants; re-cycling; soil remediation; soil washing.; Environmental chemistry; Miljökemi; Enviromental Science; Miljövetenskap;

    Sammanfattning : Contaminated soils are a large issue worldwide and much effort has been made to find efficient remediation methods. At many contaminated sites, mixtures of dif­ferent contaminants with different properties are present, which may lead to addi­tional problems, and thus additional costs, during the remediation process.

  5. 5. Biodegradation of hydrocarbons in soil and water

    Författare :Mikael Eriksson; KTH; []
    Nyckelord :Solid Phase Microextraction; SPME; biodegradation; bioremediation; bioavailability; monitoring; Volatile Organic Compounds VOC ; Screening; headspace sampling; polycyclic aromatic hydrocarbons; PAHs; aliphatic hydrocarbons; total petroleum hydrocarb;

    Sammanfattning : Biodegradation of aliphatic and polycyclic aromatichydrocarbons was studied in soil and liquid cultures attemperatures ranging from -5 º C to 20 º C undervarious aerobic or anaerobic, nitrate reducing, conditions. Twocontaminated soils were used in the studies. LÄS MER
