  2. 1. Traffic related air pollution with emphasis on particle associated polycyclic aromatic hydrocarbons : Tire wear and biodiesel exhaust emissions

    Author : Ioannis Sadiktsis; Roger Westerholm; Jan Andersson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

    Abstract : Particulate matter (PM) is regarded as one of the more important components of air pollution causing adverse health effects. A large group of compounds associated with PM are polycyclic aromatic compounds (PACs) which comprises polycyclic aromatic hydrocarbons (PAHs). READ MORE

  4. 2. On the Environmental Relevance of Platinum Group Elements

    Author : Sebastien Rauch; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; platinum; ICP-MS; automobile emission; catalyst ageing; palladium; laser ablation; urban particles; bioaccumulation; rhodium;

    Abstract : It has recently been demonstrated that platinum group elements (PGE) are released from automobile catalysts into the environment, raising concern over ecological and human health risks. However, there is still a lack of knowledge regarding the dispersion and transformation of PGE in the environment and it is therefore difficult to assess potential risks. READ MORE

  5. 3. Chemical analysis of complex mixtures with regard to potentially genotoxic organic compounds

    Author : Tomas Alsberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis describes different methods for the extraction, fractionation, and analysis of particle adsorbed organic compounds. The utility of capillary gas chromatography mass spectrometry (GC-MS) for the analysis of polycyclic aromatic compounds (PAC) is demonstrated. READ MORE

  6. 4. Investigation of HEV Li-ion Batteries for Lithium Recovery

    Author : Sravya Kosaraju; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LiFePO4 electrode; Li-ion battery recycling; Li recovery; Solvent Extraction; Dissolution study; Characterization;

    Abstract : Automobile electrification is one of the technological developments that may establish aneco-friendly transport system by mitigating vehicle emissions, and hopefully lead to a lessfossil fuel-dependent society. Conservative forecasts predict four million electric cars onthe road by 2015 (Bernhart et al., 2012). READ MORE

  7. 5. Dynamics of aluminum use in the global passenger car system: Challenges and solutions of recycling and material substitution

    Author : Roja Modaresi; Norges teknisk-naturvitenskapelige universitet (NTNU); []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis analyzes the relationship between the design of vehicles, end-of-life vehicle (ELV) management, and global material production using aluminum as an example. Vehicle manufacturing, material industries and ELV management face different challenges. READ MORE
