This book presents studies of airborne particulates and their role in human health in various geographical regions. Various methodologies are used to monitor the transport and composition of these particulates. The negative impact of antimony and its compounds on the environment and ecosystem is discussed. Furthermore, this book describes, compares and contrasts airborne particulate techniques, both theoretically and in practice. Potential human health risks related to a myriad of inorganic and organic species, especially the polycyclic aromatic hydrocarbons, requires a detailed understanding of pollutant levels both indoors and outdoors. The photochemical degradation of selected polycyclic aromatic hydrocarbons, which is being done using simulated solar UV-irradiation, is examined. Particularly urban air, in high traffic areas, containing matagenic and carcinogenic pollutants. Finally, this book describes the genotoxic effects of carbon black, fine particulates on the murine macrophages. The ultrastructural evidences of damage induced by fine and coarse air particulate matter are also discussed.
