Quantative and qualitative analysises of the heavy element concentration characteristics of 14 specimens of 9 kinds of Qingdao algae by synchrotron radiation X-ray fluorescence (SR-XRF) are presented. Results show that various algae are quite different in element concentration. Some algae reveal super concentration ability, such as Sargassum pallidum for A. and Sr, Symphyocladia latiuscula for Br and Laminaria japonica for I. Changes in the ratio of peak intensities of Mn and Fe in XRF spectrum reflect on the antagonism between elements in algae, relatively to the environment pollution. The minimum detection limit (MDL) of standard specimen, Antarctic mosses, was measured. Quantitative analysis and comparison of 10 specimens of 5 kind algae gathered from the same zone of Qingdao near-sea in 1985 and in 1999 were done, The contents of Mn, Fe, Zn, As, Br and Pb increased in 1999, in which, As in Sargassum pallidum increased 155% and Pb in Codium fragil increased 120%. The results indicated that the pollution in the near-sea of Qingdao is currently tending toward severity.
