AB 90. Recording aeroallergens at various heights
above the thessaloniki by using light aircraft and their
association with the city of meteorological data
Background: Working Purpose: Allergic diseases such as asthma exhibit
increased incidence partly due to increased concentration of allergens
in the atmosphere. The aeroallergens associated with increased asthma
exacerbations and related hospitalizations. Studies show that different
weather conditions cause variability in the distribution of allergens in the
ground. The purpose of this study was to estimate the concentration of
aeroallergens in various altitudes and the investigation of their association
with meteorological variables.
Patients and methods: Measurable concentrations of 25 different
types of allergens were recorded over the northern outskirts of the city of Thessaloniki with the help of car and light aircraft at altitudes
from the surface to 2,000 meters. The counting was done at the main
part of the period movement of aeroallergens. Studied differences
between concentrations at different heights and correlations with the
meteorological data of the region.
Results: Of the 25 different aeroallergens detected, the most populous
in the concentration recorded by the aircraft was pine, oak, grasses,
plantain and the olive tree, representing over 80% of all measurements.
Drive rate>75% were grasses. The concentrations varied at different
heights depending on the type of pollen: at higher altitudes higher
concentrations were observed for pine and oak and lower for the
grasses. The measurement period showed a direct correlation with
concentrations in various heights. The observed correlations of pollen
with meteorological data led to the development of a predictive model
of concentration in the area of interest.
Conclusions: The collection and study, but also to predict the
concentration of allergens in different heights in the atmosphere is
technically feasible. The aeroallergens fly at higher altitudes than was
thought until now. Rain as potential allergens should be taken seriously
for genesis of allergic reactions even from such heights. The detection of
pollen at high altitudes and keeping them even in extreme weather raises
questions about secure environment free of allergens and morbidity that
accompanies allergic individuals.
