The principal aim of this Volume 22 of Chemical Engineering Transactions is to involve technicians, scientists, public administrators, associations and institutions in a debate on the role of aerosols in atmospheric pollution, the actions which should be adopted and the limitations proposed by the actual regulations.
Although more than two decades have been dedicated to these subjects in an extremely abundant literature and in several meetings, the distance of the clear understandings and the little appreciations of the proposed actions seem vanify any optimistic forecast for the next future. This book should help to brifdge the existing gap.
