Topsoil and moss: chemical and radiochemical characteristics for assessing the concentration of heavy metals
Chemical characterization of soils, coupled with the analysis of epiphytic mosses, allowed the evaluation of soil effect in the bryophytes, and the origin of trace elements depositions. In soils, natural and anthropogenic radio-nuclides (I3ICS, 4'K ' 7 Be ' 22'Ra, and 2 '0Pb), macro-elements, and trace elements were analyzed; the latter, together with AI, were analyzed also in moss samples. The Enrichment Factors for mosses confirmed that soil chemical composition has a little influence on the increase of trace elements concentration in mosses, thus excluding a significant soil effect. Moss-soil combination allowed the achievement of complete and extensive information, together with the identification of the origin of heavy metals.
