| 1 | 北京首钢工业区大气重金属污染树叶的磁学响应显示文摘在北京西郊首钢工业区及附近混杂的居民区、公园绿地和农村耕作区采集了55个一年生的树叶样品,并对其进行岩石磁学和元素含量分析.结果表明:磁性矿物的含量和粒径由污染源区向周边递减.研究区域树叶的磁性由低矫顽力的磁铁矿主导.进一步研究表明样品的主要磁性参数(磁化率、非磁滞剩磁以及饱和等温剩磁)与元素Fe,Pb,Cr,V和Zn呈显著相关关系(0.73≤R≤0.88).因此树叶的磁参数可以作为大气重金属污染研究的理想替代指标. | 胡守云 段雪梅 沈明洁 Blaha U Rosler W 闫海涛 Appel E Hoffmann V | 2008 | 科学通报2008，53，4： | 19 |
| 2 | Magnetic response to atmospheric heavy metal pollution recorded by dust-loaded leaves in Shougang industrial area, western Beijing显示文摘Fifty-five evergreen tree's leaves growing less than one year were collected from Shougang industrial area in western suburb of Beijing, including steel plants and its ambient residential areas, recreational parks and farmlands. Rock magnetic properties and heavy metal contents were studied. The results show that the magnetic properties of leaf samples are predominated by low-coercivity magnetite, and both the concentration and grain size of magnetite particles gradually decreased with the distance from the main pollution source increases. Moreover, there is a significant linear relationship between magnetic parameters (the low-field magnetic susceptibility, saturation isothermal remanent magnetization and anhysteretic remanent magnetization) and heavy metals contents (Fe, Pb, V, Cr and Zn) (0.73≤R≤ 0.88). Hence, the magnetic parameters of leaves can serve as a proxy for quick detecting of the recent atmospheric metallic pollution. | HU ShouYun DUAN XueMei SHEN MingJie U BLAHA W ROESLER YAN HaiTao E APPEL V HOFFMANN | 2008 | Chinese Science Bulletin2008，53，10： | 10 |
