In recent years there has been a substantial increase in the number of patients with allergic sensitization to Olea pollen in the province of Alicante located in southeastern Spain, despite there being a low density of olive cultivation. The present investigation seeks to determine the aerobiological characteristics of Olea pollen in the city of Alicante (2010-2015), and identify and quantify the transport of Olea pollen from other source regions, defining a new parameter called External Pollen Index (EPI). This study also aims to define the Olea pollen exposure levels in Alicante by means of a new method based on statistical percentiles. The annual levels of olive pollen registered in Alicante showed: maximum concentrations in the month of May, low correlation with local meteorological parameters and significant contribution to the pollen levels from the Western Iberian Peninsula. Thus, the EPI is defined as the sum of the contributions of pollen transported by air masses from southwestern and northwestern Spain. These external contributions were obtained by cluster analysis. The good lineal correlation between the EPI and the annual pollen integral (APIn) (R2=0,818; p-valor 0,013) suggests that the total contribution of pollen from western regions may be a good predictor of the APIn of Olea pollen registered in Alicante. It has been estimated that, in the absence of external contributions, the annual Olea pollen levels in the study area would be around 1300 pollen/m3. The following Olea pollen exposure levels were determined in Alicante using a new method based on statistical percentiles: Low (<20 pollen/m3), Moderate (20–50 pollen/m3), High (51–100 pollen/m3) and Very High (>100 pollen/m3). High and very high exposure levels were associated with northwestern and southwestern contributions, respectively. Future research should consider EPI contributions in prediction models in order to get a better estimation of pollen levels in Alicante and, consequently, improve the information provided to the allergic population.
