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.
