Alternative fuels, such as gasoline-ethanol blends and biodiesel, are becoming more widespread, while the characteristics of exhaust aerosols emitted into the atmosphere and their environmental impacts are not well understood to date. Various types of diesel and biofuel were used in modern internal combustion engines under different operating conditions in order to simulate various on-road driving conditions. The multi-component aerosol collected in the exhaust was subjected to physico-chemical characterization, including particle morphology, elemental composition, organic compounds, ion contents, and surface chemistry. Ion and trace metals were observed at very low levels. Organic particle-phase compounds showed a very hydrophobic character with mostly alkane and polyaromatic functionalities.
