Zayandeh Roud is one of the most important rivers flowing in the central part of Iran. It originates from the Kouhrang Mountains. This river passes through Chahar Mahal & Bakhtiari and Esfahan Provinces and finally flows into the Gavakhouni pond. The water of this river is used for agriculture, industry and potable water. Determination of contamination level of heavy metals throughout the river is important and has a major role in controlling the ecological conditions of its environment. Clean up of the contaminations caused by heavy metals based on the natural methods including use of plants such as beech leaves will result in a healthy surrounding life while leaving no negative effects. The reason for selecting the leaves of beech tree is the abundance of this plant in different parts of Iran as well as its easy preparaation for use. In the spring of 2011, contamination level of the river to Cu, Zn, and Pb metals was measured in 6 stations and three stages and the effect of using the leaves of beech tree on the absorption of heavy metals was investigated.
