Pollen is an important allergen able to produce allergic diseases (pollinosis). An observational-descriptive research was conducted in the municipality of Boyeros in order to identify the main characteristics of pollinosis as well as its annual behavior. The approval from the municipality direction of health and of the environmental unit was obtained before starting the study. The gravimetric method was used in this aerobiological pilot study, different vaseline slides were exposed at 20 m in the roof of a hospital during 24 h. Subsequently the slides were stained with Calberla solution and the count of pollen was performed by optical microscopy in an area of 6.6 cm2 of each stained slide. Results revealed the presence of pollen in all the year under study. Pollen was more frequently detected from Casuarina trees and Gramineae plants. The highest incidence was observed during February and March. This study demonstrated the existence of pollen with allergenic importance in an urban area, where vegetation is predominant and has few industries. It is suggested to carry out similar studies in other geographical areas of the country to assess the influence of these airborne allergens in health and to contribute to the diagnosis and treatment of allergic disease with hyposensitizing vaccines.
