This volume, "Air Quality", contains many original findings on biomasss fires, transboundary pollution and associated haze and their impacts on health, biodiversity and economy and thus is expected to be a source book for research in South East Asia. Many of the results presented in this volume pertain to this region and are thus available under one ' roof.' Some papers could be discussed in graduate level classes dealing with Air Pollution, Air Quality, Cloud Physics and Biophysics. The scientific community will find this book a useful addition to their personal and institutional libraries.
