It is over. This meeting that took place in February in Trieste, was the last one on the series of the Working Group (WG) 2. The first meeting took place in Barcelona in November 2012 and after five and a half years of discussions, the first draft is here.
Some of the hot issues, that have arisen during the last meetings were brought again to the experts. Will there be finally more assessors doing the olfactometric measurement? Will the time to analyse a bag after sampling change? Will there be a new reference substance to calibrate the panel? Will there be a new design of sampler for passive sources? How will be finally uncertainty handled?
