The spatial-temporal concentration of elements harmful to life has been investigated using terrestrial mosses, Hypnum cupressiforme. The results obtained have been implemented with elements of soil collected in the same area for wider information. The results were used to identify an area of about 100 km{2}, north-west of La Spezia city, where concentrations of pollutants were higher than in the surrounding area. Soil results offer only general information and do not permit correct evaluation of man-made contamination, except, in this case, for lead and cadmium. On the contrary, mosses, which are highly efficient indicators of atmospheric pollution, have been successfully used to identify man-made polluted areas and to evaluate the fall-out rates. The employment of mosses also has economic advantages, when compared with conventional methods.
