    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Julia Jejdling; [2019]
    Keywords : occupational exposure; creosote; contaminated sites; gas chromatography-mass spectrometry GC-MS .;

    Abstract : For a long period of time, it has been common to use creosote for impregnation of railroad ties. Creosote consists of 85% polycyclic aromatic hydrocarbons (PAHs), of which some are carcinogenic and/or mutagenic. READ MORE

    Author : Tim Sinioja; [2016]
    Keywords : ;

    Abstract : Polycyclic Aromatic Hydrocarbons (PAHs) are persistent, toxic and carcinogenic environmental pollutants consisting of two or more aromatic rings. The estimation of the toxicity of PAHs can be challenging and time-consuming due to the complexity of PAH-mixtures found in the environment, for example at contaminated sites. READ MORE

  5. 4. Assessment of Pollution Levels Resulting from Biomass Gasification

    University essay from KTH/Kraft- och värmeteknologi

    Author : Emmanuel Menya; [2012]
    Keywords : producer gas cooling; condensate; PAHs; BTEX; CGCMSD; carcinogenic; toxic; downdraft gasifier;

    Abstract : Today the large scale introduction of biomass gasification is hampered by health, safety and environmental issues which present a major barrier in the deployment of this technology. The condensate in particular resulting from producer gas cooling before use in gas engines is highly toxic and carcinogenic which, if not adequately controlled, can lead to detrimental impacts on human health and the environment.
