5. 4. Polycyclic aromatic compounds (PAC) in diesel fuels and exhaust emissions : aspects of sampling techniques, chemical determination, multivariate data interpretation and PAC emissions reduction

   Författare :Hang Li; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The rapid growth in the number of motor vehicles has raised serious environmental health hazard problems in urban areas associated with vehicle exhaust emissions. Exhaust emissions from heavy duty diesel vehicles are very complex mixtures containing thousands of chemical components distributed between the particulate, semivolatile and gaseous phases. LÄS MER
