Anjum Parveen*, MUNEEBA KHAN AND SHAISTA ZEB
Abstract: An investigation of airborne pollen grains from Hyderabad: Tando-Jam, Sindh has been carried out by Burkard’s Seven Day Recording Volumetric Spore Trap. From August 2008 to July 2009. A total of 4665 pollen grains/m3 have been recorded. In this survey about 27 pollen grain types are recognized. These pollen types are Acacia/Albizia, Amaranthaceae, Asteraceae, Azadirachta indica, Brassica campestris, Callistemon citrinus, Cyperus, Daucus carota, Delonix regia, Ephedra ciliata¸ Eucalyptus globulus, Gramineae, Guaiacum officinale, Leucaena leucocephala, Mangifera indica, Moringa oleifera, Morus alba/Casuarina equisetifolia, Parkinsonia aculeata, Prosopis juliflora, Ricinus communis, Rumex dentatus, Syzygium cumini, Tamarix, Thuja and Typha angustifolia. The highest concentration of pollen grains were contributed by Grasses i.e. 1304 pollen grains/m3 followed by Amaranthaceae/Chenopodiaceae754 pollen grains/m3, Cyperus 408 pollen grains/m3, Eucalyptus 379 pollen grains/m3, Typha angustifolia 257 pollen grains/m3, Guaiacum officinale 229 pollen grains/m3, Brassica compestris 154 pollen grains/ and Leucaena leucocephala 105 pollen grains/m3. Maximum pollen concentration was abserved in the month of April-2009 i.e., 969 pollen grains/m3. The second highest peak value of pollen count was observed in the month of October-2008 i.e. 862 pollen grains/m3. The lowest concentration of pollen grains was found in January i.e., 82 pollen grains/m3.
