RESUMO
An all year round survey of atmospheric pollens and molds was made in Hat Yai, Songkla Province in the south of Thailand by Durham’s standard gravity method from 1st January 1984 to 31st December 1984. Most aeroallergens found were mold spores, with Cladosporium (Hormodendrum) on top of the list, and Helminthosporium, Alternaria, Ascospore, Fusarium, Curvalaria, Torula, Rust, Stemphylium Smut, Tetraploa, and Ledtosporium were found to be less common in that order. Grass pollens were found in low counts, as well as weed pollens, which most of them belong to the group of Chenopod-Amaranthus. Unidentifiable pollens were found in high counts, and were probably the pollens of para rubber, cashew, corn, oil palm or wattle. The atmospheric pollens and mold spores were found throughout the year with highest peak in summer and lowest in November and December when there was heavy rain.
