Abstract	Pollen grains are known as one of the important bioparticles causing allergic manifestation in human beings. Hence, knowledge of season and prevalence of the airborne allergens to which the patients are exposed is a prerequisite for the diagnosis and treatment of patients suffering from allergic disorders. Keeping this in view, aeropalynological study was carried out in the atmosphere of Rohtak city for two consecutive years (July, 2007–June, 2009), using a volumetric spore trap. A total of 31 pollen types were recorded during the survey period. In the two years of study, March–April and July – October, were identified as the pollen seasons for Rohtak city. Average annual pollen catch of 59,750 grains was obtained with 80–85% of pollen recorded from February to May. The highest monthly counts were recorded in the month of September and July for the first and second year, respectively. The principal pollen producers were Cannabis sativa (28.9%), Poaceae (20.6 %), Cheno/ Amaranth (10.5 %) and Parthenium hysterophorus (6.8 %). Fourteen pollen types contributing more than 2% to the total catch were represented in the form of a pollen calendar. A significant positive correlation (p>0.001) of total pollen count with maximum and minimum temperature was observed.
