  1. 11. SOURCES OF DIOXINS TO BALTIC AIR Volatilization and Resuspension As Potential Secondary Sources of Dioxins to Air

    Master-uppsats, Kemiska institutionen

    Författare :Van Anh Le; [2011]
    Nyckelord :;

    Sammanfattning : Persistent organic pollutants (POPs) are ubiquitous contaminants characterized by semi-volatility, low water solubility, high lipophilicity and inherent toxicity. A combination of these properties results in long-rang transport, bioaccumulation and biomagnification through food webs. LÄS MER

  3. 12. Atmospheric Deposition of Legacy and Emerging Persistent Organic Pollutants in Northern Sweden

    Master-uppsats, Kemiska institutionen

    Författare :Seth Newton; [2011]
    Nyckelord :;

    Sammanfattning : Bulk atmospheric deposition samples using Amberlite IRA- 743 as an absorbent for hydrophobic pollutants were taken every two months for one year at two different locations in northern Sweden. A method was developed for the analysis of various legacy and emerging POPs in these samples based on GC-HRMS. LÄS MER

  4. 13. Biodegradation of Aliphatic Chlorinated Hydrocarbon (PCE, TCE and DCE) in Contaminated Soil.

    Magister-uppsats, Institutionen för tema

    Författare :Aloysius Tibui; [2006]
    Nyckelord :Aerobic biodegradation; Anaerobic biodegradation; Inorganic fertilizers.; Chlorinated compounds; Tetrachloroethene PCE ; Trichloroethene TCE ; Dichloroethene DCE ; Mico-organisms; Methane; basis mineral medium; Gas Chromatography GC ;

    Sammanfattning : Soil bottles and soil slurry experiments were conducted to investigate the effect of some additives on the aerobic and anaerobic biodegradation of chlorinated aliphatic hydrocarbons; tetrachloroethylene (PCE), trichloroethylene (TCE) and dichloroethylene (DCE) in a contaminated soil from Startvätten AB Linköping Sweden. For the aerobic degradation study the soil sample was divided into two groups, one was fertilised. LÄS MER

  5. 14. Inventering av förorenad mark på LKAB's industriområden i Kiruna, Svappavaara och Malmberget

    Magister-uppsats, SLU/Div. of Soil Chemistry and Pedology

    Författare :Camilla Esberg; [2005]
    Nyckelord :MIFO; LKAB; förorenade områden; riskklassningar; oljegropar; järnmalmsgruva; gruvdrift;

    Sammanfattning : The county administration asked LKAB to make an inventory of possibly contaminated sites caused by their mining activity. The inventory should be performed according to the MIFO model, a method from SEPA which is used to assess a contaminated site. LÄS MER

  7. 15. Analysis of some Chlorinated Pesticides in Jordanian Ground- and Surface Waters by Solid-Phase Extraction and Mass Spectrometric Detection- A Method development

    Magister-uppsats, Tema vatten i natur och samhälle

    Författare :Lara Shahin; [2004]
    Nyckelord :Ecology; Decomposition; Jordan; pesticides; PS-DVB; SPE; Ekologi;

    Sammanfattning : A solid-phase extraction (SPE) method was developed for the determination of organochlorine pesticides, namely aldrin, alpha-BHC, beta-BHC, delta-BHC, dieldrin, endosulfan I, endosulfan II, endosulfan sulfate, endrin, endrin aldehyde, lindane, heptachlor, heptachlor epoxide, 4,4’-DDD, 4,4’-DDE and 4,4’- DDT in water. The effect of extraction conditions, such as the addition of sodium chloride and methanol to the sample prior to loading was studied. LÄS MER
