Raw materials are fundamental to the economy, and hence to growth and jobs, and they are essential for maintaining and improving our quality of life. Securing reliable, sustainable and economic access to certain ‘critical’ raw materials is of growing concern around the globe. But it is as well a priority to acquire detailed information about the distribution of PTE and POP both at regional and local scales for environmental issues. The latter are of fundamental importance for environmental risk assessment and analysis that have a crucial role in the evaluation of human health risk, especially in mining and intensive urbanized areas. In addition, geochemical knowledge of the territory and mostly of top soils, where the main agricultural products grow, to become the foods for citizens, may be useful for land-use planning. Geochemical exploration methods are widely used to manage, visualize, analyse and interpret data for further identifying geochemical anomalies, for both the discovery of new ore bodies and for environmental purposes.
