Abstract:
This study demonstrates the negative impact of pollen load on quality of life
caused by pollen allergy. This study revealed seasonal fluctuations in pollen
concentrations in Islamabad. The Pakistan Meteorological Department provided a set of
data (2019-2021) of daily Temperature, Rainfall, Wind and Pollen concentration . Pollen
from 8 allergenic species (Paper Melburry, Grasses, Acacia, Pines, Cannnabis,
Eucalyptus, Dandelion, Alternaria) were identified. After the study, this Broussonetia
papyifera is the cause of highest pollen levels and thus may have played a key role in
exacerbating pollen allergy symptoms in the city. Pollen concentrations were high in
March, when climatic conditions were favorable for a large pollen. Meteorological
conditions such as maximum and minimum daily temperature had significant positive
effects on daily pollen counts, while relative humidity and precipitation were negatively
correlated with pollen data. Furthermore, an analysis of weekly pollen counts and weekly
visits of allergy patients found a clear positive relationship between these two variables
as pollen count and Covid-19 plot suggesting that prolonged lockdown had positive effect
on the atmosphere. Specially in the month of march and april the pollen concentration
increase from its highest level limit given by WHO. In the light of these findings, some
measures should be taken as Paper Mulberry plant should be trimmed as it grows and an
alternative specie could be planted to reduce the effect of Paper Mulberry (Broussonetia
papyifera) in Islamabad.
