The International Symposium on Olfaction and Electronic Nose (ISOEN) took place as planned in Aveiro, Portugal at the end of May 2022. Despite its title, ISOEN conferences have sessions not only with electronic noses but with a much broader set of devices that have in common the aim to detect things electronically such as electronic tongues, sensors for non-odorants, air quality, health, etc.
The conference was structured in several sessions to try to fit the over 100 papers received in this occasion. This was the first conference hold face-to-face in a long time after an online break during the pandemia.
Instrumental Odour Monitoring Systems (IOMS) represent the only tool available for environmental monitoring capable to perform real-time characterization of ambient air. They have been commonly used to assess odour impact at receptors thanks to their capability to detect odours and identify their provenance. An emerging application of IOMS concerns the real-time monitoring of emissions at plant fencelines. To do this, IOMS must provide a fast and accurate measurement of the odour concentration. 
In May 2015 the decision was made, by a positive vote in Technical Committee 264 ‘Air Quality” of the Committee Européen de Normalisation (CEN), to establish a preliminary work item “Air quality – Continuous instrumental odorant monitoring in air to assess risks of odour (nuisance) and safety” which was entrusted to working group WG41 "Electronic sensors for odorant monitoring" for a period of 6 years starting on 2015-05-12. The Dutch member of CEN, NEN, was assigned the secretariat and the author of this article was appointed as convenor.
