Downstream Distribution and Postdepositional Mobilization of Cadmium in Alluvial Soils

Table 2

Dominant types of alluvial soil profiles from Belgium and Luxemburg according to Swennen and Van der Sluys [35].

Type 1Dominantly nonanthropogenically influenced geochemical distributionABackground concentrations are displayed throughout the profile
BAnomalous values because of the presence of heavy minerals
CAnomalous values because of base metal mineralizations

Type 2Clear evidence of anthropogenic influenceAGradual increase of metal(loid) content in upper part
BDramatic increase in pollution related elements by industrial activities

Type 3Features related to pedogenic translocation of mobile elements
