Interaction Between Air Pollution, Pollens and Allergic Rhinitis

For this study, the investigators will collect real life data from volunteer citizens via the MASK-air® mobile application, and exposure data to air pollutants and pollens from their partners. The data will be collected over one year in order to cover all pollen seasons. A communication of the project will be deployed to the citizens in the study area. The recruitment of participants will be done via an internet page accessible to all and presenting the MISTRAL study. Interested citizens can then access the electronic consent platform. After signing the participation agreement, they will receive a link to download the MASK-air® mobile application (freely available via the Android and Apple stores) and a personal study code, which will allow them to install the application on their smartphone. Participants will report their symptoms on the MASK-air app on a daily basis. Entry will only take 1 minute/day. This real-life data will be correlated with air pollution and pollen exposure data. In anticipation of the prevention actions that will be deployed by the public authorities following this study, an analysis of the expectations and needs of the citizens will be carried out among a part of the participants in the form of 4 questionnaires.
