Il Biomonitoraggio di Pollutanti nell'Aria mediante i Muschi.

Abstract

The spatial-temporalconcentration of elements harmful for life has been investigated using terrestrial mosses of the HYPNUM CUPRESSIFORME Species. The results obtained have been implemented with elements of soil collected in the same area, for a wider information. Investigated areas in La Spezia province consist of two different areas, the first approximately 1000 Km2 with 220.000 inhabitants, various factories and an important termoelectrical power installation, the second one 3.5 Km2 with a blead factory recycling exhausted accumuletor batteries. Concerning the mosses, the investigated elements are: Al, As, Cd, Co, Cr, Fe, Mn, Ni, Pb, Cu, Ti, V,e Zn. The elements investigated on soil samples, collected only once, are: As, Cd, Cr, Mn, Ni, Cu, e Pb. The results obtained allowed to identify an area of about 100 Km2, located North- West with regard to La Spezia city, where the concentrations are higher than the remaining area.
