How we can be sure our air is safe to breathe? This album introduces the principles and concepts of air quality management and looks at how we analyse pollution control problems. Five video tracks review the nature and characteristics of air pollution today and demonstrate how air quality data is interpreted. They include a comparison between shipping and car emission levels, the processes used to remove pollutants from the air, and ways in which British Aerospace could limit its Volatile Organic Compound emissions in the future. This material forms part of T308 Environmental monitoring, modelling and control.
