Each year, the Pollens of ambroisie, a very invasive and well -installed plant in the region, participate in annual allergies as soon as the beautiful days return. Its grains can indeed trigger rhinitis, conjunctivitis, tracheitis, and even, once in two, asthma.

It spreads thanks to human activity: sites, displacements of earth, materials … The origin of allergies to pollens is therefore mainly on roads and agricultural plots. In Burgundy-Franche-Comté, the departments of Nièvre, Saône-et-Loire and Jura are the most affected in the region. Côte-d’Or is not spared.

Surveillance of pollens in the air, provided by Atmo Bourgogne-Franche-Comté, had revealed in 2024, during the observation of the Ambroisie, an allergic risk of exposure to its Pollens of several weeks: six for Nièvre, four for Saône-et-Loire and a week for Jura. The number of people sensitive to pollens also increases each year.

To combat the propagation of ambrosia, it is necessary to eliminate the plant and prevent the scattering of the seeds. If you spot an Ambrosia plant,report it on the website reporting-ambroisie.fr or by email contact@signalement-ambroisie.fr.
