|Abstract: ||Pollen is routinely monitored, but it is unknown whether pollen counts represent
allergen exposure. We therefore simultaneously determined olive pollen and Ole e
1 in ambient air in C ordoba, Spain, and Evora, Portugal, using Hirst-type traps
for pollen and high-volume cascade impactors for allergen.
Pollen from different days released 12-fold different amounts of Ole e 1 per
pollen (both locations P < 0.001). Average allergen release from pollen (pollen
potency) was much higher in C ordoba (3.9 pg Ole e 1/pollen) than in Evora
(0.8 pg Ole e 1/pollen, P = 0.004). Indeed, yearly olive pollen counts in C ordoba
were 2.4 times higher than in Evora, but Ole e 1 concentrations were 7.6 times
higher. When modeling the origin of the pollen, >40% of Ole e 1 exposure in
Evora was explained by high-potency pollen originating from the south of Spain.
Thus, olive pollen can vary substantially in allergen release, even though they are
