  1. 1. Multidisciplinary perspectives on a natural attenuation zone in a PCE-contaminated aquifer

    University essay from Lunds universitet/Geologiska institutionen

    Author : Robin Jansson; [2018]
    Keywords : DCIP; groundwater chemistry; Tetrachlorethene; PCE; natural attenuation; Earth and Environmental Sciences;

    Abstract : The old dry-cleaner in Hagfors, is one of the most seriously tetrachloroethene (PCE) contaminated sites in Sweden. Ever since the pollution was discovered in the groundwater in the 1990s, the site has undergone remedi-ation two times with limited success. READ MORE

  3. 2. Modeling of ozone and nitrogen oxides pollutions in urban air environments

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Author : Henrik Reimer; [2018]
    Keywords : Ozone; Nitrogen oxides; NOx; Hydrocarbons; VOC; Urban environment; Model; Pollutions; Physics and Astronomy;

    Abstract : As the air quality in urban environments is a rising problem, a deeper understanding of how air pollution is dependent on different factors is necessary. In these environments, there are different parameters that effect how the chemical reactions of the pollutants are proceeding. READ MORE

  4. 3. Isobutanol - An alternative biofuel for hand-held petrol products

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Jens Janssen; [2018]
    Keywords : Isobutanol; biofuel; emission; two-stroke;

    Abstract : Pollution and environmental concerns require further improvements in engine technologyas well as research of alternative fuels. Users of handheld products are directlyexposed to the exhaust gas and thus to the occurring emissions, which cancause significant damage. Pursuing to reduce emissions is therefore a vital task.

  5. 4. Application of ERT and IP for localisation of chlorinated hydrocarbons at a former dry-cleaning facility

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Hedda Jönsson; Anna Wiberg; [2017]
    Keywords : Chlorinated hydrocarbons; PCE; Hagforstvätten; Geophysics; Resistivity; Chargeability; Geological features; Man-made structures; Technology and Engineering; Earth and Environmental Sciences;

    Abstract : At Hagforstvätten a dry-cleaning facility operated 1970 – 1993 and leached huge amounts of tetrachloroethene (PCE) to soil and groundwater. This study was conducted at the contaminated site and focused on applying the geophysical methods Electrical Resistivity Tomography (ERT) and Induced Polarization (IP) to investigate if it was possible to locate source zone, degradation zones and groundwater plumes of PCE.

  6. 5. Pathways and Transit Time of Meltwater in the Englacial Drainage System of Rabots Glacier, Kebnekaise, Sweden

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Caroline Coch; [2014]
    Keywords : dye tracing experiments; glacier hydrology; hydrocarbon pollution;

    Abstract : Following the crash of a Norwegian Hercules aircraft on Rabots glaciär in the Kebnekaise mountain range in 2012, a field campaign was initiated in order to assess the fate of the hydrocarbon pollution in the system. It is hypothesized that soluble components of the aircraft fuel will be transported within the glacial meltwater. READ MORE
