Air Pollution Engineering Manual

Recently, I have been supported by this encyclopedia. I'm love this book and waiting for new addition.

The only complaint I might have with this book is the format, it's a big book, and given how often I need it, a smaller handbook (like the CRC handbook) would be more convenient. But then that might hurt the readability.The book itself however is awesome, comprehensive, readable, plenty of illustrations, minimum of jargon, and useful for engineers and scientists.
