Foreword

Abstract

This special number of BBL is devoted to the proceedings of a minisymposium recently held at C.I.S.B. and centered on urban pollution.  The aim was to exploit the interdisciplinary mission of the C.I.S.B. Center in order to provide colleagues from different backgrounds an opportunity to exchange ideas and results over a topic drawing a more and more widespread attention.  The chosen format for the  C.I.S.B. minisymposia consists in a half-day session including 6 - 7 contributions, each of about 30' plus discussion.  Such  relatively light format should encourage participation of anybody (particularly young people)  eager to discuss his own results in front of colleagues sharing the same attitude towards  significant data,  evidence-based interpretations and realistic models.
