Abstract:
The physical-chemistry characteristics of carbonaceous aerosols, produced by ships, burning diesel and heavy fuel oils, are studied. The morphology, elemental composition, ion and organic fractions, surface chemistry of particles, sampled from exhaust of ship diesel engines in cruising conditions are investigated by electron microscopy, infrared spectroscopy, ion chromatography, gas chromatography-mass spectrometry, and gravimetric analysis. The comparative analysis of particles shows the common characteristics and features depending on the fuel type. Aerosol, produced by ships, using heavy fuel oil, demonstrate a great variety of environmentally dangerous organic compounds, metal oxides, sulfates, and salts. Their high hygroscopicity relates to ship track formation and climate impacts induced by shipping.
