Introduction: Exposure to airborne pollen from certain plants can cause allergic disease, but allergens can also be found in non-pollen-bearing fractions of ambient air. This may explain why the allergic response in susceptible patients does not always coincide with the presence and magnitude of airborne pollen counts. Plantago pollen is an important cause of pollinosis in northern Mediterranean countries, but it is difficult to determine its incidence in allergies because Plantago pollen appears in the atmosphere at the same time as grass pollen.

In this study, we sampled airborne pollen grains in the city of León (NW, Spain) from January 1995 to December 2011, by using a Burkard® 7-day-recording trap.

The prevalence of allergy to Platanus is currently moderate, although the percentage of monosensitized patients is low. This hinders accurate interpretation of the relationship between the amount of pollen inhaled and the patient's symptoms.

- The study highlights that pollen counts often include Urtica, a non-allergenic plant, leading to incomplete data on allergens in the atmosphere, especially concerning allergic reactions.
- The objective was to compare Urticaceae pollen counts with actual concentrations of allergenic proteins (Par j 1 and Par j 2) in two areas in Spain, using advanced sampling and quantification methods.
- Results showed varying pollen and allergen levels between locations and years, with a key finding that there was a weak correlation between Urticaceae pollen and allergen concentrations, suggesting a need to include allergen measurements in future aerobiological studies for more accurate allergy assessments.
Article Synopsis
- The paper investigates the behavior of alder pollen in Ponferrada, Spain, examining its counts from 1995 to 2006 and focusing on the influence of weather conditions.
- The main pollination period for alder occurs in January-February, and the study finds that temperature, especially maximum temperature, has the strongest positive correlation with pollen counts.
- Multivariate and correlation analyses reveal that high pollen counts are associated with warm temperatures, low rainfall, and specific humidity levels, emphasizing the need for diverse analysis methods to accurately track pollen variations.
