Abstract:

In order to study the relationship between the plant and the environment, and to make an inquiry into the function of testing surrounding, without a standard specimen, we had analyzed 6 species of algae and lichen about elements in the Fildes Peninsula of Antarctica by mini-beam XRF. Specimens are Ulva pertusa , Halymenia sp. and Lyngbya major which belong to algae, and Cladonia borealis , C. fimbriata and Usnea sp. which belong to lichen. The result turns out to be that various algae show different absorption for every elements. In XRF spectra, Ulva pertusa possesses more elements than Halymenia sp., like Br, As and Rb. The content of Cu and Zn is high too. In XRF spectra of Lyngbya major , the content of K is lower than Ca, the content of Zn is high. The element component in 3 species of lichen of Antarctica is very similar each other,but the relative content of Mn, Fe, Cu and Zn is different.
