About the book
Urban aerosols are present in almost all cities worldwide, especially those with many mobile and point sources releasing emissions from the burning of fossil fuels. These pollutants produce health and environmental impacts related to their concentration, size, and chemical composition, with the finest aerosols being those that cause the greatest public health detriment due to the ability to penetrate deep areas causing respiratory and cardiovascular diseases. In air pollution events with high aerosol concentrations, people are exposed to high doses of these pollutants, generating increased hospital admissions for respiratory diseases. In the environment, they modify the local earth energy balance due to the absorption of a part of the energy emitted into the atmosphere. Greenhouse gases typically absorb this energy, but the absorption by black carbon aerosols is larger. Moreover, changes in land use that predominate in many cities (deforested areas or without vegetation cover, waterproof pavements, conglomerates of buildings, reduced green spaces) affect the local temperature through phenomena such as the urban heat island, which intensity increases due to the presence of urban aerosols.
This book intends to provide the reader with a comprehensive overview of the current state-of-the-art of urban aerosols, from the emission sources to the environmental and health impacts, going through the characterization, transport and transformation of the aerosols in cities.
