Determination of some trace metals in the leaves and periderm of Avundodonax L. distribution in Lattakia city using Atomic Absorption Spectrophotmetry

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.
