Abstract

The number of patients of pollinosis caused by airborne pollen is increasing rapidly in the world. From a global perspective, pollinosis from birch is a serious problem in Europe, North America, and Northeast Asia. Our aim in this research is to generalize the principle of our pollen emission model developed for cedar. We observed temporal variations in airborne pollen concentrations of birch in Hokkaido, Japan, by using a Hirst-type pollen sampler. Relationship between airborne birch pollen and meteorological conditions during the main dispersal period was analyzed. Our results indicate that airborne pollen concentrations are related to changes in air temperature and solar radiation. The derivative of air temperature is most important and effective factor than the air temperature itself. The air temperature change for shorter time was related to the pollen emission of birch compared with the case of cedar. The amount of birch pollen emitted from the flowering birch forest was formulated using the algorithm summarized from the analysis.
