Urban airborne particulate matter : origin chemistry fate and health impacts This book presents research and information regarding the origin chemistry fate and health impacts of airborne particulate matter in urban areas a topic which has received a great deal of attention in recent years due to documented relationships between exposure and health effects such as asthma. With researchers and academics presenting their work and key concepts and approaches from a variety of disciplines including environmental and analytical chemistry biology toxicology mineralogy and the geosciences this book addresses the topic of urban airborne particulate matter in a multidisciplinary manner. Topics and research addressed in the book range from common methodological approaches used to sample and analyse the composition of airborne particulates to our knowledge regarding their potential to impact human health and the various policy approaches taken internationally to regulate particulate matter levels
