Abstract
For some time, the allergenic potential of pollen has been spreading on the world's population,
the amplification and the development of respiratory diseases such as seasonal allergic rhinitis
and the worsening of asthma symptoms are of concern.
In order to study the pollen content in the atmosphere and the effect of meteorological
parameters including the wind on pollen production, a daily aeropalynological study over a
period of more than two months was carried out in the city of Khenchela, using the Durham
gravimetric method.
Our study has highlighted the abundance of pollens in the atmosphere of the city even in the
autumn period. A third of all pollen collected is highly allergic. A total of 1271 grains of
pollen belonging to 14 species and genera were captured. in these 14 species and genera,
some are unobserved in the environment of the study or catchment site such as cedar and
juniperus sp, located outside the field of view; their pollens would be very anemophilous.
The number and type of pollen collected shows that Plantago sp and grasses are the most
represented in the samples respectively with 411 and 241 on the 1271, which could be
explained by their important anemophilic properties. The same for Anethum graveolens also
for Phoenix dactylifera very use as tree alignment also for Artimisia sp a medicinal species
growing in the peripheral of the city, which has a very strong allergenic potential.
Our survey showed that the allergy is under diagnosed and underestimated. Allergy sufferers
dramatize the symptoms, and often treat it with self-medication with influenza drugs or often
consulting a general doctor.
