This is a study of the physical and chemical properties of carbonaceous aerosols emitted by transport systems (namely, by aircraft gas turbine engines and large ship diesel engines) into the atmosphere. A comparative analysis of the morphology, size, elemental composition, and surface chemistry between aviation and diesel soot particles reveals the general and characteristic features of emissions from each source. The high pollution rate of diesel soot particles, considerable fraction of metal admixtures, and availability of char particles characterize the specific features of the formation of particles of this type. The main characteristics characterizing the interaction between aviation and shipping emission aerosols in the moist atmosphere (the composition of organic and water-soluble fractions at the surface) have been obtained. Due to high hygroscopicity, the microparticles can generate cloud condensation nuclei and initiate contrails and additional tropospheric cloudiness.
