Abstract
The concentration of airborne cedar pollen particles and the level of cedar pollen allergen (Cry j1) were measured in 2-Japanese private houses. The samples were collected with gravitational settlement method and also with as 8stage-type Andersen sampler.<br>During March through the beginning of April, the concentration of cedar pollen was 1.5-3.6grains/m3 in 2005, and 0.2-0.5grains/m3 in 2006. The allergen (cry j1) concentration was 15.9-23.2pg/m3 in 2005, and bellow 1.5-2.2pg/m3 in 2006.<br>The intrusion rate of cedar pollen to private house indoor was estimated as 0.5%, calculating as ratio of indoor value/outdoor value.<br>It was calculated that each ordinary indoor cedar pollen particle was corresponded to 6 pg of Cry j1 respectively.
