As 886
Co 100
Cu 1735
Pb 493
Zn 2404

Metal-rich cinders covered
with an unpolluted 0.15 m
layer of soil. Both
cinders and soil were
mixed with sand (1:1
w/w) in pot experiment.

Populus and Salix 2 years Coarse and fine roots

provided a significant
sink for contaminants with
both TF and BCF < 1

Biochar (20% v/v)

Miscanthus 8 months Biomass yield increased

by 2-4 times with GWC;
