Abstract: The town of Annaba (East of Algeria) is characterized by a very polluted atmosphere, which became a dangerous for the fauna and the plants, the regional planning and environment ministry has installed an of air quality control network , baptized SAMASAFIA which is composed of 4 stations of air quality monitoring: Station 1 (Annaba), station 2 (El Bouni), station 3 (Sidi Amar), station 4 (Airoport). This study consists to use the pollen as bio-indicator of pollution. The pollen of Malus communis (Rosaceae) and Phoenix dactylifera (Arecaceae), have been exposed to air during 24 h inside the 4 stations of SAMASAFIA. The analysis of SAMASAFIA showed the existence of pollution caused especially by the dust (78 � g m � 24 h 1) notably at EL Bouni sites. The results showed after 24 h of exposure a considerable decrease in germination percentages at EL Bouni (87-37%) with a loss of 50%. This investigation has permited to combine data of the physico-chemical analysis of network SAMASAFIA with the biological data of the pollen viability in order to estimate the air quality.
