[The fungal flora of Ankara air in January 1972 and 1974 and its relationship to allergic diseases].

The fungal flora of the air in Ankara was searched during first week of January 1972 and 1974. Different areas of the city were chosen for investigation. The central and outskirt areas showed different patterns of fungal flora during January 1972 and January 1974. In the central areas there was a remarkable decrease in yeast flora between the two years. However, mould flora was increased in some extent. No notable difference could be detected in outskirt areas. Penicillium and Aspergillus species were isolated most frequently. It is concluded that this flora was influenced by heavy pollution of the air in Ankara. This pollution is caused mainly by: (1) Heating systems with crude coal and oil, (2) Heavy motor traffic, (3) Geographical situation of the city, cup-shaped land with poor air draughts.
