Bibliography: pages 182-202. / Cladosporium, in general, is the dominant atmospheric fungal spore. Fungal spores are, quantitatively, the dominant partner in the atmosphere. Meteorological factors such as wind speed and wind direction, precipitation, temperature, relative humidity, atmospheric pressure and atmospheric stability have been identified as affecting air spora concentrations and an attempt is made to explain the relationships involved. A thorough review of particle behaviour and current sampling methods indicates that the Burkard volumetric sampler was best suited for airspora sampling in Cape Town. Results of the research confirm that Poacear is the dominant pollen, but basidiospores are the dominant nant spores in the atmosphere.
