"This volume is one of the outcomes of the project 'International legal obligations related to Prevention, Preparedness, Response and Recovery from CBRN events and status of their implementation in Italy - CBRN-Italy' (ref. no. 20175M8L32), which has been funded by the Italian Ministry of University and Research as a Research Project of National Relevance. The CBRN-Italy project has been carried out since 2019 by the Scuola Superiore Sant'Anna (which is also the lead partner of the Project), the University of Bologna, the University of Florence and the University of Turin ... This volume traces its origin to a number of events organised (in person and online) within the framework of the CBRN-Italy project to discuss the findings of research activities carried out by contributors..."--ECIP Preface.
