Mosses and soil have been assessed by using the total deposition of metals deriving from anthropic origin. Samples have been taken from 23 sites within an area surrounding the country of La Spezia and having an area of 900 km{2}. The concentration values of a series of elements determined in both moss and soil samples from different sampling stations has allowed the identification of the area mostly exposed to dustfall. Inside an innercircle of 5 km radius from the power station the concentration of Hg, Cd, As, Cu, Co, S and V were found to be 3 to 10 fold higher than the average values of the entire test area. The results show that mosses appear the best bioaccumulators, indicating reliably the atmospheric outfall.
