Abstract :

Abstract Industrial activities cause the arrival of large amounts of heavy metals into the atmosphere and the usages of plant species can be effective in reducing the pollution of heavy metals. This research attempted to evaluate the amount of Cadmium absorption in different parts of Cupressus arizonicaand Fraxinus excelsiorin Isfahan. For this reason samples from leaves and surface roots were collected in polluted sites and controlled site at the end of spring and summer and the concentration of Cadmium was measured by Atomic Absorption (AA). The results indicated that the amount of Cadmium absorption in the above ground organs of Cupressus arizonicawas more than the Fraxinus excelsiorspecies. In both species, the trees leaf absorbs Cadmium more than the root. The Azadi Street absorbs Cadmium more than other site. The most and the least amount of cadmium absorption was observed on September and July respectively.
