Abstract

大気中の粒子状物質の調査として,クロマツ葉に付着した粒子に着目した。自動車交通や工場などの産業活動が盛んな神戸市においてクロマツ苗木を設置し,葉表面の粒子状物質を電界放射型走査電子顕微鏡による個別粒子分析法を用いて,形態観察および化学組成を分析した。化学組成値をもとにクラスター分析を行った結果,粒子は5種類に分類された。それらは,(I)Si,Al,Mg,Ca,Feなどを含む粒子,(II)Siを多く含む粒子,(III)Na,Clから成る粒子,(IV)Caを多く含む粒子,(V)Feを多く含む粒子,の5つのクラスターである。粒子の化学組成と形態から,それぞれのクラスターにおける粒子の発生源の検討を試みた。土壌粒子や海塩粒子など自然起源の粒子や,鉄球粒子やブレーキ磨耗粒子などの人為起源の粒子が存在した。

Airborne particulate pollution has increased in the urban area. Black pine seedlings were settled in the eastern part of Kobe city where located in heavy traffic and industrial area. Needles of these seedlings were collected 1, 2, 5 and 8 weeks after settling. Individual particles on the surface of pine needles were observed by using FESEM. The chemical composition was analyzed by single particle analysis. To estimate possible sources of the atmospheric particles in Kobe area, all particles were classified according to their chemical compositions by cluster analysis. Cluster analysis showed five different particle types. They contained many anthropogenic particles, e.g. fly ash particles, iron ball, brake wear and also natural origin sources such as soil particles.
