Paolo Zannetti

Dr. Paolo Zannetti, QEP is Adjunct Professor of Environmental Sciences at the Wessex Institute (WIT), Ashurst, UK.

He has collaborated with WIT for more than three decades:
• From 1980 he has delivered the Air Pollution and Pollution Modeling courses at WIT.
• He founded as Editor-in-Chief the WIT journal Environmental Software in 1986, now published by Elsevier as Environmental Modeling and Software.
• He founded as Editor-in-Chief the WIT conference cycle ENVIROSOFT (1986-1998).
• In 1990 he authored the WIT textbook Air Pollution Modeling, which was the first comprehensive book in the field and is still a widely used textbook.
• Starting in 1983, he has been one of the founding editors of the WIT AIR POLLUTION conference cycle.
• In 1993-96 he produced as Editor-in-Chief the three volumes of the WIT book series Environmental Modeling.

Dr. Zannetti has performed studies and scientific research in environmental sciences for four decades. His activities have covered pure research in the fields of atmospheric sciences and numerical modeling, written publications, seminars and courses, project management, environmental consulting, editorial productions, and expert testimony. His major field of investigation and competence is air pollution. He has written more than 300 publications, and 40+ books and book chapters, including the book “Air Pollution Modeling” ¹, completed in 1990, which was the first comprehensive book in the field and is still today a widely used textbook.

He has studied many air pollution cases throughout the world. In particular, in the first phase of his scientific career, he studied and modeled the air pollution affecting the city of Venice, Italy2, and was the project manager in Kuwait of the first comprehensive air pollution study (monitoring and modeling) in the Persian Gulf.3 In the last 20 years, Dr. Zannetti has investigated hundreds of accidental and regular releases caused by industrial, transportation, and agricultural activities, throughout the world.

He has often used computer models to simulate the transport and fate of atmospheric chemicals. In most of these cases, he simulated the ambient concentrations caused by the emissions using his own computer models (AVACTA II4 , MONTECARLO5) and/or those developed and recommended by government agencies, such as the US Environmental Protection Agency (US EPA). In particular, he performed pioneering work for the development of new Lagrangian modeling techniques in which air pollution is simulated by computer methods using a series of independent segments6, puffs7, or particles.8

He is often invited to present talks at conferences and seminars throughout the world. In particular, he has taught air pollution courses in Italy (University of Bari-Taranto), California (Berkeley Extension), Kuwait (Kuwait Institute for Scientific Research, KISR, and Kuwait Foundation for the Advancement of Sciences, KFAS), and at the Wessex Institute of Technology, WIT, where he is Professor of Environmental Sciences.

Dr. Zannetti’s professional credentials have been certified9 with the title of Qualified Environmental Professional (QEP), given by the Institute of Professional Environmental Practice (IPEP). The QEP certification recognizes professional achievements for environmental professionals and their compliance with the highest of ethical and professional standards.
