大気浮遊じん試料を原研東海研の定点で3年間、捕集した。近年、所内で防砂林の伐採が行われた。そこで防砂林の伐採前後における大気浮遊じんの元素組成の変動を分析した。Sc/Na比-Cl/Na比のような元素濃度比の分布図から大半の試料が海塩粒子と土壌粒子の混合物から成ることがわかった。また、防砂林の伐採前後にそれぞれ捕集した大気浮遊じんの元素組成に違いがあることがわかった。

Airborne dust samples were collected with a high-volume sampler at a fixed point in JAERI-Tokai for three years. Recently at JAERI-Tokai, a number of pine trees to arrest sand shifting was cut down. We analyzed the variation in elemental composition of the dust collected before and after felling the trees. It found, from the two-dimentional plots of ratio of elemental concentration such as Sc/Na-Cl/Na ratios, almost all samples consisted of mixture of sea-salt and soil. There were some differences between the elemental composition of the dust collected before and after felling the trees.
