8 oCtober 2012
The chairs and vice chairs of the Scientific Committees met on 8 October 2012 in or-der to discuss general issues related to the Committees. Topics discussed at the meet-ing were: collaboration with other community bodies, joint opinions, horizontal activities and other general matters. Agreement was reached on the way forward on documents on Future Challenges in Risk Assessment and Making Risk Assessments more Relevant for Risk Managers. Both will be further developed as discussion documents and not as opinions. The outcome of the meeting was found to be very positive by the participants.
