Abstract:
A qualitative and quantitative evaluation of pollen
concentration in the atmosphere of Abha city, Saudi Arabia with the relation
to meteorological parameters is presented. Investigations were undertaken
from January to December 2006 using a Burkard 7 day volumetric spore trap.
A total of 6,492 pollen grains m-3 belonging to 50 pollen taxa
was detected. Poaceae represented 55.1% of total pollen, Leguminosae (11.7%),
Compositae (6.1%), Solanaceae (4.6%) and Cupressaceae (4.2%). Pollen grains
were found throughout the year. July represented the highest peak of pollen
number and also the highest pollen taxa. The monthly variation of pollen
taxa and their relationship to meteorological parameters were investigated.
It was found that the pollen concentration is positively correlated with
temperature and negatively correlated with rainfall, relative humidity
and wind velocity. May-September represented the months of highest pollen
number (95% of total pollen).
