The aim of this study was to determine the trace of some heavy metals elements pb,
Cd, Cu, Zn & Fe in the leaves and periderm of the Avundodonax L. using Atomic
absorption spectroscopy. The samples were collected from twenty locations and divided
into four groups according to traffic and human activities.
The results showed an excess in the concentration of lead, cadmium and copper in
the leaves and periderm of the Avundodonax L., which enables the use of this plant as a
vital indicator for the pollution by these heavy metals. The concentration of cadmium in
the leaves and periderm ranged between (0.231- 6.278ppm) and for lead between(1.057-
47.592ppm) and copper between(1.022 -45.771ppm). While the concentration of both zinc
and iron remained within the permissible natural limits.
