Abstract: Air dispersion of viable algae in the extramural environment of Pune have been studied for six months, fortnightly from October 2011 to March 2012 by impaction culture method using BBM medium. As per the existing record of 24 algal aeroallergens, we found 15 genera and 21 species at Pune. These belong to Cyanophyceae 11 Genera &21 species, Chlorophyceae 2 genera and Bacillariophyceae 2 genera i.e. Anabaena (6 Sp.), Phormidium (4 Sp.) and Calothrix (3 Sp.) etc. recorded causing allergy in sensitive victims. Out of totally recorded 228 airborne algal genera we found 40 algal genera and 29 species of which 3 have been found to be new record for aerobiology in India. These are Camptylonema Sp., Dichothrix Sp. and Psedoanabaena Sp. During this study 528 colony unit have been selected randomly, which revealed maximum percentage contribution of Chroococcus Sp. (14.9%) as dominant genus followed by Chlorella and Chlamydomonas (9.96%) each to the total aerophycoflora. Hence, it has been proved that these three unicellular algal forms have been found to be dominant as compared to colonial and filamentous forms of algae. Site wise dispersion and distribution of aeroalgae raveled that maximum 12 genera have been recorded at site no.5 followed by site no.6 (11 genera) and minimum at site no. 3 (3 genera). Site wise frequency studies revealed highest count of Anabaena (188 out of 528 regularly at all the six sites) followed by Chlorella (178 out of 528) and Phormidium (170 out of 528).Only Anabaena was found at all the six sites constantly, while Gloeocapsa (at Site no.6), Scytonema (Site no. 5) and Aulsoria (Site no.5) each at single site only and absent at remaining five sites.
