D-NOSES stands for Distributed Network for Odour Sensing, Empowerment and Sustainability. This 3 year-long project is supported by International Associations, experts in citizen science, odour and sustainability experts, local administrations and public bodies. The important part of validation has just commenced with cases studies in Portugal, Spain, Greece and Bulgaria.

   This DNOSES project will study the use of mapping odour annoyance to describe and study the impact of this environmental vector. The idea is to launch several case studies to see how better use this tool that links odour with annoyance.

   The 19th and 20th of March, the Working Group (WG) 41 of the European Standard Organization met in Milan to discuss several issues related to  Instrumental Odour Monitoring Systems (IOMS) or so called e-noses. This new standard was on the brisk of being downgraded to a technical specification, because the text developed by the experts was lacking a development on the first stage of Quality Assurance Level (QAL1), among other things.

   The European regulation allowed in the mandatory area only EN 15267 certified automated measuring systems (AMS) for the continuous measurements of air pollution. However, the QAL1-certification for AMS instruments cannot be applied, as is, for IOMS. The QAL1 certification clearly needs an adaptation to the complexities of measuring odours according to the 2 reference methods considered in this standard, the EN 13725 and the EN 16841.
