The Bahía Blanca airborne pollen monitoring station became operational in mid-1994. The aim of this station is to research on the composition of airborne pollen in the Bahía Blanca city and in areas with natural vegetation (“pampa”, “monte” and saline steppe). Sampling was carried out daily in Bahía Blanca and weekly in three surrounding natural areas: Salitral de la Vidriera (30 km from Bahía Blanca), Marahué (90 km from Bahía Blanca), Parque Provincial E. Tornquist (100 Km from Bahía Blanca). In Bahia Blanca sampling is carried out continuously using a volumetric impact sampler (Rotorod model 40). In the natural areas, a portable volumetric impact sampler was placed 1.5 m above the ground during a two-hour period on the sampling day. In the Parque Provincial E. Tornquist sampling was carried out at 649, 822 and 950 meters above the sea. Observations of flowering in the field were carried out at the same time as the aerial sampling. Concentrations of counted pollen grains are reported as pollen/m3 of the air. The most importants pollen types that were identified are: Bahía Blanca: Cupressaceae, Amaranthus/Chenopodiaceae, Fraxinus, Poaceae, Myrtaceae. Marahué: Amaranthus/Chenopodiaceae, Poaceae, Myrtaceae, Brassicaceae and Plantago. Salitral de la Vidriera: Amaranthus/Chenopodiaceae, Poaceae, Ambrosia, Centaurea and Urticaceae. Parque Provincial E. Tornquist: Pinus, Poaceae, Cupressaceae, Ambrosia and Alnus. This study was conducted within the Proyecto Grupo de Investigación of the Secretaría de Ciencia y Tecnología, Universidad Nacional del Sur (PGI 24/B155).
