Coriolis, 31057 Toulouse cedex Key words: allergens, meteorological factors, pollen, prevention, environmental monitoring Page(s) : 341-9 Published in: 2005 Because daily pollen counts depend strongly on the dispersive qualities of the air (horizontal and vertical winds), we tested an atmospheric dispersion index already validated for pollutants in the Paris area for pollens for the 2004 season (March to September). The study indicates that high index values are accurately associated with pollens from trees (birch, ash, oak, plane) and graminaceous plants, with a time lag of zero to two days. Pollen forecasts, initially experimental, could be useful for persons with allergies, healthcare providers, and the health authorities.
