Atlante geochimico-ambientale d’Italia

Area 04 – Scienze della terra

The Geochemical Atlas of Italy addresses the need for a large scale geochemical mapping based on FOREGS procedures. The aim of the Geochemical Atlas of Italy is to define background/baseline chemical element values on a national scale and it will help government decision makers in defining trigger and action limits on a local scale, bearing in mind the complex spatial variability of Italian geology.Topsoils, subsoils, stream waters, stream sediments and floodplain sediments have been collected all over the italian territory divided into 27 sampling cells according to the Global Terrestrial Network (GTN) established by the Global Geochemical Baseline project (IGCP 360). 348 geochemical maps have been produced on the basis of both an accurate statistical analytical process and a fractal filtering interpolation method
