Hg, As and V soil disposition in the Italian regions of Umbria and the Marches as estimated through the use of mosses
42 soil samples and six species of mosses were collected in the Regions Umbria and Marche; in addiction, a control site (Torricchio) located in a Natural Reserve of Marche has been choosen in order to evaluate As, Hg and V distribution. The procedures for sampling, preparation, mineralisation and analysis followed the rules approved by A.N.P.A. (Cenci, 1999). The average of Hg in the mosses was 0.1 mg kg-1, in agreement with the Hg content in mosses collected in Europe Countries (Rulhing and Steinnen, 1998) in low polluted areas. The amount of Hg in soil samples ranged from 0.05 to 0.11 mg kg-1. In Umbria Region, the contents of As and V in mosses were 2.5 time greater than those found in the Natural Reserve, whereas the relative concentrations in soil samples were comparable (14.8 and 13.2 mg kg-1 of As; 72 and 82 mg kg-1 of V in Umbria and Torricchio sampling areas, respectively). Results obtained indicated that environmental pollution in Umbria and Marche sampling areas was almost neglected.
