Background and aims: Respiratory diseases, such as asthma, rhinitis and allergies, are increasing worldwide, in association with a greater presence of different etiological triggers in the air, from which pollen is one of the most important. These evidences show the importance of monitoring airborne pollen concentrations for preventive or possible control purposes. This paper reports the incidence and prevalence of airborne pollen content as well as the allergenic pollen types present in the air of Sunchales city (Santa Fe, Argentina) during two study periods (August - November 2012, August - December 2013) aiming to present a preliminary pollen monitoring for the city. M&M: The samples were collected with a Burkard trap located 1.3 m above the ground with a suction volume of 0.6 m3 h-1. The entire slide was analyzed with an optical microscope at 400x final magnification. The daily concentration (gr m-3) was determined for the recognized pollen types. Pollen recognition and their allergenicity were determined with specialized literature. Results & Conclusions: Compared to other cities in the country, species richness is high, although the daily concentration for the period analyzed is low. The majority of the captured pollen (about 70%) corresponds to only four pollen types (Cupressaceae, Moraceae, Poaceae and Urticaceae) reported in the literature as allergens. [ABSTRACT FROM AUTHOR]
