摘要: 以鸢尾(Iris tectorum Maxim.)为材料,采用干洗法测定其叶片的滞尘量,采用电感耦合等离子体发射光谱(ICP)测定其叶内及叶表的颗粒物成分及含量,并研究不同风速和不同风力作用时间下鸢尾的大气颗粒物再悬浮比例。结果表明,鸢尾叶片的单位面积滞尘量为3.43 g/m2,在草本植物中是比较高的。鸢尾叶表元素及叶内元素中只有Al和K存在显著相关性,风速对沉降于鸢尾叶片表面的大气颗粒物的再悬浮有着显著的影响,而风力作用时间的长短对大气颗粒物的再悬浮影响作用有限。

Abstract: Taking Iris tectorum Maxim. as the material,and the dust content was determined by dry-cleaning method. The composition and content of the particulate matter in the leaf and on the leaf surface were determined by ICP. In addition,resuspension ratio of atmospheric particulate on the leaf surface of I. tectorum was investigated at different wind speed and different time. The results showed that the amount of dust per unit leaf area was 3.43 g/m2,which was relatively high among the herbs. Only Al and K had significant correlations between the interior leaf elements and exterior elements. And wind speed gave significant effect on the resuspension of atmospheric particulates in I. Tectorum,while the wind function time gave the limited effect on the resuspension of atmospheric particulate matter.

Key words: Iris tectorum Maxim., phytoremediation, air pollution, ICP, resuspension
