Abstract

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
