Low-Cost Pollen and Allergy Symptoms Monitoring with Beenose Sampler and Livepollen App: The Case Study of the Metz City, France, During Spring 2023

The increasing prevalence of pollen allergies and their health impact, coupled with the limitations of the current pollen measurement system, require the development of new monitoring strategies and better dissemination of the information to the population. The measurements of a Beenose real-time pollen sensor located in Pouilly, near Metz (France), and a Hirst reference station in the centre of Metz, are considered for the study of the most allergenic species from 20 March to 25 June 2023, mainly Betulaceae and grass. These measurements, which are concordant, are correlated to symptom data obtained from the LivePollen app, which allows users to voluntarily report their allergic symptoms. Strong correlations are found between the symptom reports and the pollen concentrations shifted by one day, depending on the pollen species and the period of interest. The limitations of the data collection methods, the quality of user reports, and the influence of air quality are discussed. Such studies should be extended to other locations and time periods. Considering these promising first results, it seems that future real-time pollen monitoring can help allergy sufferers and healthcare professionals to better diagnose, anticipate, and reduce allergic crises by correlating their symptoms with pollen peaks.
