Mar 01, 2017 1. Introduction. Vanadium is widely distributed in sedimentary and igneous rocks and minerals as a mildly incompatible, refractory, lithophilic element, which is mainly mined in South Africa, Russia and China (Huang et al., 2015).Under natural conditions, vanadium mobilization in soils is often decoupled from other metals and metalloids, and is governed by weathering and redox processes

Occurrence of Vanadium in Belgian and European Alluvial Soils

Vanadium (V) is a naturally occurring trace element, but total concentrations in soils and sediments are also dependent on the parent material and might be influenced by anthropogenic activities (e.g., steel industry). Despite the fact that threshold values for V in soils and/or sediments exist in various European countries, in Belgium, V is not taken into account when the environmental
