Abstract

In the City of Annaba, respiratory diseases are important causes of consultation and hospitalization. To contribute to the development of the research as for the biological and environmental pollution, it seemed to us essential to establish a pollen calendar of the city of Annaba. The objective of this study is to know the variability of its allergenic pollen component. The pollen calendar offers a preventive therapeutic util ity because it supplies the critical dates of the pollination so allowing knowing the periods about high allergenic risks. For this study, we chose a gravimetric method, using the pollen sensor of Durham. The results we obtained have revealed the existence of pollen from trees or grasses, their monthly average as well as various pollen peaks where these are plentiful in the air of Annaba. The elaboration of the average pollen calendar allowed us to distinguish the seasons in the course of which the allergen ic pollen component is plentiful in the air as well as its duration of appearance, periods in the course of which the allergenic symptoms are the most important. The knowledge of the pollen seasons is necessary. It allows us to prevent the appearance of th e likely allergic symptoms when the pollen concentration of the air is intense. It is necessary to act as first aids to the public. Thanks to this knowledge the more precise planning of the rhythm of the desensitization of the allergic individuals is possi ble and easier. We determined the monthly behavior of main allergenic pollens, which we confronted with the weather conditions (pluviometry, temperature and humidity averages). The objective is to manage with this work to make forecasts of the appearance o f the pollen rains when the weather conditions are similar. This revealed us that the weather conditions act on the presence of the pollen and its abundance in the air.
