Abstract. ONE YEAR OF AIRBORNE POLLEN SAMPLING IN MAR DEL PLATA (ARGENTINA). A continuous aeropalynological survey of the atmosphere of Mar del Plata was carried out from December 1992 to November 1993 using a Burkard volumetric spore trap. Ten-day averages were calculated for 28 relevant taxa, selected on the basis of their relative high concentration in the air. The total annual concentration (Cupressaceae pollen excluded) was 84,445 grains/m3, with 42 % of total appearing during September and October. Pollen spectrum largely reflects urban anemophylous vegetation, which is characterised by spontaneous herbs and by ornamental shrub and tree species. A qualitative analysis shows two major pollen seasons related to the atmospheric dominance of either arboreal or non arboreal pollen.
