スギ花粉による室内汚染レベル，室内侵入率および花粉1個に対するCrv j1量

摘要

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 an 8stage-type Andersen sampler. During March through the beginning of April, the concentration of cedar pollen was 1.5?3.6 grains/m~3 in 2005, and 0.2?0.5 grains/m~3 in 2006. The allergen (cry j1) concentration was 15.9?23.2 pg/m~3 in 2005, and bellow 1.5?2.2 pg/m~3 in 2006. The intrusion rate of cedar pollen to private house indoor was estimated as 0.5%, calculating as ratio of indoor value/outdoor value. It was calculated that each ordinary indoor cedar pollen particle was corresponded to 6 pg of Cry j1 respectively.%2005年、2006年にわたり、野外環境と室内環境にて、スギ花粉rn粒子とそのアレルゲンであるCry j1量の測定を行った結果から、以rn下のことがいえる。
