Popis: | An aeroallergen survey in two provinces, Chiangmai in the northern and Songkhla in the southern part of Thailand which are 1 500 km apart, was done in 1986 and 1987 using a rotorod sampler. The five most common pollen types and mold spores were: Chiangmai: Mold spores: Cladosporium, rust, Fusarium, Nigrospora, 1-celled spore. Pollen grains: Mimosa, wild grasses, Urticaceae, Cyperaceae, tetrad pollen. Songkhla: Mold spores: Cladosporium, rust, Nigrospora, Papularia, 1-celled spore. Pollen grains: Casuarina, Mimosa, Urticaceae, Cyperaceae, wild grass. There were definite differences in the amount and frequency of occurrences of aeroallergens between these two provinces. Furthermore, some specific pollen and mold spores, such as tetrads and Mimosa pollen, were found only in Chiangmai, and Casuarina pollen and Papularia spores only in Songkhla. These findings might be caused by the differences in geography, plantation and meteorological data. |
