Abstract The Network of Survey for Airborne contaminants (RNSA) monitors pollen concentrations for all the identifiable species since 1985. This monitoring is based on a dense network of 400 sensors spread all over France. The technique used in the network allows getting a concentration of pollen grains every two hours. These data have been since the beginning associated with records from a panel of doctors to give a second level of information on allergic symptoms. OpenHealth.fr designed and is publishing a health indicator aiming to monitor allergic rhinitis using drug sales data (mainly antihistamines) from over 4600 pharmacies. Data is available since 2010. The relationship between allergy symptoms and the presence of pollens in the atmosphere has been well established by combining all the data. The concept is based on the comparison on the day mean of pollen concentration and the health indicator. To date, the relationship between pollution events, meteorological parameters and the allergic rhinitis has not been achieved. Our study aims to understand their respective relevance according three distinct pollution events in the search of new triggers to prevent sanitary risks. We present here preliminary results on the relationship between allergic rhinitis, pollen concentration and pollution events.
