Since the first edition was printed in 1991, there have only been minor changes in air regulations. The opposing "trenches" used by environmental regulation proponents have deepened as each side increases their database. Agencies and environmental groups have backed off a little in issues such as bubble policies and enforcement time tables. This has made it extremely difficult for equipment vendors to anticipate industry requirements. Overall, the current market projections are not very favorable for the new equipment suppliers.
In contrast, the service organizations are seeing increasing need for their help in areas such as dispersion modeling, troubleshooting and testing. Existing systems are being improved upon to keep them in operation. There remains a continuous need for up-to-date references and training materials to serve these needs, and it is for this purpose this revised edition is dedicated.

"The strength of Hesketh's book lies in the emphasis on practical application that you would expect from an engineer/consultant in this field, and the coherence of the treatment of the material within the author's scope of specialization."
-R. F. Griffiths, in TransIChemE.
