This book provides a strong interdisciplinary approach in presenting topics on Air Pollution by integrating chemistry, physics, meteorology, engineering, health effects, policy, and regulatory aspects. It addresses the requirements of undergraduate/graduate students in Science/Engineering opting Air Pollution courses at a basic level by dealing exhaustively the fundamental aspects of air pollution with suitable examples and worked out problems. Meteorological aspects of dispersion of air pollutants, modeling techniques for air quality assessment, prediction, health risks, up-to-date information on different air quality management approaches and regulatory preventive measures adopted by various countries are presented with supporting data. Present Global & National air pollution scenarios and latest developments in Preventive Measures for air pollution control, emissions inventory? Comparison with emission standards, assessment of emission flows and emission factors are presented with critical explanation. To provide technological perspectives for undergraduate /graduate Engineering students, the scientific and engineering aspects of air pollution monitoring, assessment predictive modelling, air pollution control technologies, air pollution from automobiles noise pollution and methodologies for frequently used in Air Permit Applications-Screening Techniques are discussed with applications which will expose the students to various software programs used in this area. The specialty of this book is that it extensively deals on various aspects of air pollution, providing up-to-date information on global air pollution trends, preventive measures adopted by different countries, latest modeling techniques for air quality assessment/prediction/management and state of art air pollution control technologies with suitable examples, illustrations and worked out problems. A Stronger systems approach is adopted in presenting the nature of air pollutants, their dispersion under different meteorological conditions, associated human health Risks, measures, models, and control technologies of air pollution at scale ? starting at the individual/niche level and expanding to local /regional /global scale. The present book serves the needs of undergraduate/graduate students in Science and Engineering pursuing Air Pollution Course both as a basic introductory or as an advanced Core course and also as a resource material for researchers/practicing professionals in this important area.
