The originality of the city of Annaba is that it is situated between two big ecological surroundings, to know, the Mediterranean sea to the north and the forest covering the massif of the Edough to the west. It incited us to determine to what point the vegetation of massif, influence it atmospheric pollen of the city of Annaba, notably in pollens allergisants. Of our survey, it comes out again that the region of Annaba is submitted to the influence of the massif of the Edough, because pollinic specter has reveled that nearly the half of pollens atmospheric identified belongs to the forest plants. The remainder of pollen belongs to humid, swampy, uncultivated zone species and of culture plants. In the end we can said that: the topography, the climatic conditions, and the speed of wind are factors determining the richness of the atmospheric in pollen.
