The relationships between the levels of the air pollution and the levels of heavy metals in Bryum argenteum Hedw. and Parmelia tinctorum were investigated. The concentrations of Ca, Al, K, Fe and Na in Bryum argenteum Hedw. and Parmelia tinctorum were higher than another elements. These results were similar to previous paper. The differences of relative concentration (concentration/geometrical average concentration) of Hg in Bryum argenteum Hedw. at various sampling points were not recognized. The main reason is that the concentrations of Hg and Sb originated from both of the soil and industrial pollution. Then the enrichment factors (EF) were calculated to exclude the effect of the soil origin. The EF of the man-made element in Bryum argenteum Hedw. at the urban sites were higher than those at the rural sites.
