Abstract
The concentration of airborne cedar pollen particles and the level of cedar pollen allergen (Cry j1) were measured in a Japanese private house. The samples were collected with gravitational settlement method and also with an 8stage-type Andersen sampler. During March through the beginning of April, the concentration of cedar pollen was 1.5〜0.5 grains/m^3 in 2003, and 0.4〜0.3 grains/m^3 in 2004. The allergen Cry j1 concentration was 8.0〜1.8pg/m^3 in 2003, and bellow 1.6pg/m^3 in 2004. From the comparison of the particulate count of cedar pollen and cedar pollen allergen level in each height of gravitational settle plate position, we reached the conclusion that there existed allergen particles with much smaller in size and different in shape in the air besides the ordinary cedar pollen. The calculation shows that each ordinary indoor cedar pollen particle has 6pg of Cry j1 respectively.
