[Evolution of pollinization in France (2002)].
It was traditional until these last years to supervise the evolution of pollination by taking account only of the evolution of the number of grains of pollens present per m3 of air per year on each site. If this factor is significant, it is not sufficient. Indeed, it is essential to be able to supervise the evolution of the number of days in the year when the allergic risk related to a pollen is significant. The work which is presented shows over the years 1992 to 2002, for some sites of the RNSA (Amiens, Paris, Rouen, Strasbourg, Montlucon, Bordeaux, Lyon, Marseille, Toulouse) that there can be parallelism of the curves "pollinic counts" and "allergic risk", but also of light discordances. Should a thorough study of the dates of appearance supplement this work because these modifications can be the consequence of the climatic motions of these last decades.
