  4. 3. Using a biotrickling filter for degradation of cypermethrin, an insecticide frequently used in Tahuapalca, Bolivia

    Master-uppsats, Kemi; Tekniska högskolan

    Författare :Henric Enstedt; [2013]
    Nyckelord :Biofilter; Trickling filter; Fungus; Cypermethrin; Pesticides; Ninhydrin;

    Sammanfattning : The feasibility of using bench-scale biotrickling filter reactors inoculated with the fungus UBAF004, isolated from soil in Tahuapalca, for treatment of water contaminated with cypermethrin was investigated. Wood chips, gravel and ceramics were tested as packing materials for the reactors in batch experiments in small glass flasks. LÄS MER

  5. 4. Degradation of Cypermethrin by indigenous bacteria in local industrial, beech- and spruce-forest soil

    Magister-uppsats, Sektionen för ekonomi och teknik (SET)

    Författare :Joakim Engblom; [2007]
    Nyckelord :Pyrethroids; Cypermethrin; Soil-bacteria; Beech-forest soil; Spruce-forest soil; Industrial soil; Microcosms;

    Sammanfattning : Soil from local beech-forest, spruce-forest and an industrial area was taken. Control- and test-microcosms containing 150 ml soil were spiked with cypermethrin 0,4 mg/ml soil. Cypermethrin residues were extracted on day seven and 14. Cyclohexane and deionized water was utilized in multiple step extraction processes. LÄS MER
