title: Atmospheric pollen in the area of Athens.
abstract: In this paper the results of an investigation on the pollen grains in the atmosphere of Athens, Greece, are presented. The work was carried out between June 1973 and August 1974. A gravity sampler, of the Durham type, was placed on the roof of King Paul Athens General Hospital. Slides covered with vaseline were exposed to the air for 24 h every day during the above-mentioned period. After staining , the pollen on each slide was counted in an area of 1.375 cm2 under a light microscope. The results obtained gave an indication of the approximate pollination period for each plant taxon and also the degree of pollen concentration over a particular area in Athens. Twenty-two types of pollen were found. Those that predominated are from Olea europaea (olive tree), Pinus Urticaceae, Plantago (plantains), Chenopodium (goose-foot), Rumex (docks), Eucalyptus and two as yet non-determined types. Most of them are found in the air duing the period March-July.
