Eléments traces métalliques dans les sols. Contribution à l'étude de leur déterminisme spatial en Région limoneuse belge. ; Metallic trace elements in soils. Contributive study of driving factors of their spatial distribution in the Belgian Loamy region

The natural background levels of metallic trace elements (MTEs) in cultiva-ted soils should be known in order (i) to understand the processes in which MTEs are involved and (ii) settle a reference system dedicated to the the ap-praisal of agricultural practices, to the detection of contaminations, or to the time-course follow-up of regional values. A methodological framework has thus been set up to evaluate the importance of natural driving factors, the pe-dogeochemical background, of the spatial distribution of MTEs in soils and also to compare the current levels of MTEs content in agricultur...
