Heavy metal distribution in some French forest soils: evidence for atmospheric contamination [PDF]

open access: yes, 2003
This study is one of very few dealing with the distribution and the origin of heavy metals in French soils from a priori non-polluted forest areas. The abundance of heavy metals measured in these soils decreases as follows: Cr) Zn)Pb)Ni)Cu)Co4Cd. Total
