48 006a   An Odour Attribution Study is undertaken in North America for an Air Quality Management Agency that includes athering data from specific sources and ambient locations to better understand odour impacts within the local communities. Specifically, the following objectives were to be met:

  Identify odorant compounds impacting the area of concern via comprehensive quantitative and qualitative analyses; Determine the relative contribution and variability of the odorant compounds emitted from the three key source facilities; Develop a strategy for continuous real-time odorant monitoring to measure emissions impacting the community from the three key source facilities.

isoen2022 conference   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.

Webb   Biofiltration is not a one-size-fits-all technology. In order to properly design the biological odour control process, the foul air source needs to be accurately characterized. The optimal biological odour control configuration will depend strongly on the compounds contributing to odour. Considering the application of biological odour control to wastewater treatment plants specifically, this paper first describes the most common odorous compounds and how each can be biologically degraded.

   Several case studies demonstrate the importance of selecting the proper biological technology based on the foul air source. This paper is intended as a Manual of Best Practices for environmental professionals interested in applying the latest developments in advanced biological odour control techniques.
