The levels of atomospheric pollution in Okayama city were discussed by using the levels of heavy metals in mosses (Bryum argenteum Hedw.). The moss samples were collected from ten sites in Okayama. The metals in mosses were analyzed by X-ray fluorescence analysis and atomic absorption spectrophotometry. The concentrations of trace mercury were also analyzed by frameless atomic absorption spectrophotometry with a combustion-gold trapping heat vaporization technique. In results, metal values for mosses collected from the areas of relatively higher level of air pollution and or the areas of varying traffic densities were higher than the value from the other, and it was suggested that amounts of heavy metals such as mercury in mosses were able to be used as an indicater of the air pollution.
