摘要：
The annual airborne pollen variation of the Porto region was studied from November 2001 to October 2002 using a Cour type sampler. A total of 170 × 106 grains m-2 belonging to 63 taxa was observed. The vegetation surrounding the sampling point includes ornamental, non-ornamental trees, shrubs and herbaceous species. The main pollen types were Cupressaceae, Gramineae, Hamamelidaceae, Pinaceae, Urticaceae, Quercus spp., Acer spp., Myrtaceae, Caryophyllaceae, Oleaceae, Betulaceae and Plantago spp. that represented 88% of the Porto pollen spectrum. Gramineae, Cupressaceae, Myrtaceae, Oleaceae, Pinaceae and Urticaceae pollen are found throughout the year. Concerning total pollen concentration, the distribution throughout the year is very irregular, with several annual peaks, with the maximum concentration registered between the end of March and the first two weeks of April and the lowest observed during autumn.
