Hailed on first publication as a masterful review of the topic, The Science of Air: Concepts and Applications quickly became a standard resource in the field. Clearly written and user-friendly, the second edition continues to provide the scientific underpinnings of the essence of air. Major expansions include: Air math and physicsAir flow parametersIndoor air qualityRegulatory updates related to indoor and outdoor air qualityUpdated air pollution control technologies The text follows a pattern that is nontraditional, using a paradigm based on real-world experience. It covers air resource utilization and air protection, contains regulatory updates related to air quality, and provides an update on pollution control technologies. In addition to the discussion of numerous mitigation and remediation procedures, this authoritative resource includes an expanded section on the fundamentals of air chemistry and physics, making it an indispensable text for those tasked with compliance to air pollution laws. The common thread woven through the fabric of this text is air resource utilization and its protection.Numerous examples exist on how understanding the science of air can assist in understanding global climate change, air pollution, radon, indoor air quality, and acid rain. To solve these problems and understand the issues related to air, air pollution control practitioners need a broad base of scientific information from which to draw — The Science of Air fills this critical need.
