All topsoil samples were analyzed for HCl- or DTPA-extractable Cd.
Samples from both stations were analyzed for exchangeable, reducible, oxidizable and residual soluble Cd according to a modification
of the BCR (the ‘Community of Bureau of Reference’, now ‘Standards,
Measurements and Testing Program of the European Community’
method) (Luo and Christie, 1998a,b).
