Heavy metals such as cadmium, lead, copper and zinc generated from municipal, industrial and agricultural activities lead to extent pollution of soil and water in the world. Regard to custom methods of removing heavy metals from water and soil are so expensive, difficult and insuccessful, so using of plants that can diminish pollution, is necessary. In the other hand importance of extending silviculture in Iran leads us to study adsorbing heavy metals by Eucalyptus camaldulensis. This study were carried out with samples of leaves and soils that gathered from pollutant area of south of Tehran and Khozestan provenance and copper, zinc, cadmium and lead were estimated with inductively coupled plasma. Results were analyzed with combined analysis design. Content of zinc, lead and cadmium in all places were significantly different also all samples and interaction of samples and place for zinc and lead were significant. Maximum amount of copper, zinc, lead and cadmium in soil were respectively 173±2.6, 123±2.7, 151±2.6, 1.46±0.025 and in plant were 33±0.76, 327±6.3, 220±4.4, 2.9±0.05 mg.kg-1D.W. that confers Eucalyptus camaldulensis can accumulate lead and zinc. In the other hand lead and zinc are greatly generate from traffic and industrial activities so this plants can use for diminish of environmental pollution.
