Abstract

Abstract:

The atmospheric pollution of Urumqi city is being a serious problem due to the expansion of industrial area, increasing number of vehicles and population density. We analyzed 8 trace elements including Al, Fe, Mn, Zn, K, Mg, Ca and Na in 6 lichen species collected from non-polluted areas of August First forest farm by inductively couple plasma atomic emission spectrometry (ICP-AES). The results showed that different species of lichen had different accumulation capacities to the same elements and even the same variety of lichen showed various accumulation abilities to various trace elements. It is suggested that the lichen species of Xanthoria elegans (Link) Th. Fr. can be used as a bio-indicator in monitoring of heavy metals pollution.

Key words: lichen, bio-indication, trace elements, air monitoring
