Abstract :The aeropalynogical study of the atmosphere of El-Hadjar town was carried out during one year, from June 1, 2012 to May 31, 2013. The collected pollen during the sampling period yielded 2729 pollen grains/cm2 belonging to 50 taxa, distributed on 20 families insert ignore into journalissuearticles values(Apiaceae, Arecaceae, Asteraceae, Boraginaceae, Brassicaceae, Caryophyllaceae, Chenopodiaceae/Amaranthaceae, Cupressaceae, Cyperaceae, Ericaceae, Fabaceae, Lamiaceae, Mimosaceae, Pinaceae, Poaceae, Rosaceae, Scrophulariaceae, Ulmaceae, Urticaceae and Vitaceae.);; 24 genera insert ignore into journalissuearticles values(Alnus, Artemisia, Betula, Borago, Carya, Casuarina, Echium, Ephedra, Eucalyptus, Fraxinus, Juglans, Juncus, Ligustrum, Mercurialis, Melia, Pistacia, Plantago, Platanus, Populus, Quercus, Rumex, Salix, Tilia and Trifolium.); and, 6 species insert ignore into journalissuearticles values(Castanea sativa, Corylus avellana, Olea europaea, Quercus ilex, Ricinus communis and Typha angustifolia);. The pollen peak concentration was recorded in April with 715 GP/cm2 and the minimum value in October with 36.08 GP/cm2. The pollen spectrum has a percentage of 52.31% of pollen tree. The Cupressaceae family contributed with 12.84%, Olea europaea with 6.95%, Eucalyptus and Casuarina with 5.85 and 5.71%. The highest percentage of this type of pollen occurs in November with 90.51%, dominated by Casuarina pollen with 86.31%. The highest concentrations of tree taxa are: Eucalyptus insert ignore into journalissuearticles values(35.03%); and Ligustrum insert ignore into journalissuearticles values(16.21%); in June. Fraxinus with 64.64% in December, Ericaceae 17.42% in March; Olea europaea and Quercus in April with 18.86% and 6.79% respectively. The pollens of the herbs present 44.89%. They are characterized by the major presence of Poaceae and Mercurialis pollen with the following percentages: 21.49% and 11.75%. It seems that the months of July insert ignore into journalissuearticles values(86.33%); and August insert ignore into journalissuearticles values(80.14%); mark the highest percentages of non-tree pollenKeywords : Aeropalynology, allergenic pollens, atmospheric pollens, El Hadjar region Algeria,
