Studies on atmospheric pollens in the Philippines

Abstract

The predominant pollen in the Philippines is the grass pollen, followed by Mimosa, Moraceae, Cyperaceae, lower vascular plants spores, Amaranth, Coconut, Tiliaceae, Pinus, Compositae and Alnus (in decreasing order of significance). The atmospheric pollen pollution in Quezon City is heavy in November, December and January; in Los Banos during January, February, March, April, June and November; and in Baguio City during February, March, April and May. Compared to the density of pollution in these areas, the incidence of pollen pollution in Bacolod City, Davao City and Naga City is very light.
