摘要:

采用电感耦合等离子光谱直读法,对乌鲁木齐南山八一林场的6 种不同地衣体内的Al、Fe、Mn、Zn、Ca、K、Mg、Na 8 种微量元素含量进行测定。测定结果的方差分析表明,不同种类的地衣对同一种微量元素的富集能力不同,对不同微量元素的富集能力也不相同,其中壳状地衣(Xanthoria elegans(Link) Th. Fr.)可作为一种良好的生物指示材料用于环境重金属污染监测。

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
