Typology of soils from peri-industrial areas of the Walloon region (Belgium) based on trace metal elements contents.

Soils from urban and peri-industrial regions are affected by the presence of technogenic susbstrates and the fallout of smoke and dust dispersed by the winds in the vicinity of pollution sources. Pollutant levels in these soils display significantly higher variability than in soils that remained close to natural state. Identification of the factor controlling this variability is the first step toward prediction and mapping of pollutant levels in such soils. This work is aimed at characterizing the distribution of trace metal concentrations in urban and peri-industrial soils from the Walloon re... Mehr ...
