abstract = {Phytomanagement used on soils contaminated with metals aims to stabilize
them in the soil. It generally uses less demanding tree species such
as maple, poplar, and black locust. However, it is important to consider
the rate of accumulation of metals in the leaves as well as their
location (leaf blade/petiole) together with the contents of cell
wall compounds (hemicelluloses, cellulose, lignin). These two aspects
are likely not only to have repercussions on the decomposition of
litter but also to lead to a possible transfer ofmetal contamination
into the food chain via soil decomposers/detritivorous. A successful
phytoremediation is therefore the result of compromise: no tree species
can meet all these criteria. The results obtained show that poplar
is not recommended due to a high accumulation of Cd and Zn. The most
appropriate species among our 3 studied species, which seem the most
suitable in terms of remediation of metal polluted soils, could be
the black locust and the maple which are less susceptible to contribute

Phytomanagement used on soils contaminated with metals aims to stabilize
them in the soil. It generally uses less demanding tree species such
as maple, poplar, and black locust. However, it is important to consider
the rate of accumulation of metals in the leaves as well as their
location (leaf blade/petiole) together with the contents of cell
wall compounds (hemicelluloses, cellulose, lignin). These two aspects
are likely not only to have repercussions on the decomposition of
litter but also to lead to a possible transfer ofmetal contamination
into the food chain via soil decomposers/detritivorous. A successful
phytoremediation is therefore the result of compromise: no tree species
can meet all these criteria. The results obtained show that poplar
is not recommended due to a high accumulation of Cd and Zn. The most
appropriate species among our 3 studied species, which seem the most
suitable in terms of remediation of metal polluted soils, could be
the black locust and the maple which are less susceptible to contribute
to the transfer of exogenous metals such as Cd to the trophic chain.
However, maple strongly accumulates Pb in the leaf blade and it is
susceptible to degrade quickly due to its high hemicelluloses and
cellulose contents and low lignin content. The black locust accumulates
metals mainly in the petiole (little consumed by detritivorous).
