Five plant residues samples of wood chips (WC), ryegrass roots
(RR), orange peels (OP), bamboo leaves (BL), and pine needles (PN)
were chosen as model biosorbents. Wood chip, including residues
from industrial transformation to forest waste, is a commonmaterial
which present as fill at many industrial sites and is also a main
component of solid waste . Ryegrass is a potential candidate
for POPs remediation and the sorption of pollutants to the root tissue
may be an important process for this end .
