Determination of some Heavy Metals in Extraction of plants by using different solvents

Abstract

The present study was conduct to determination of the contents of Extraction of plants leaves with heavy metals, the samples represent five different types of leaves were Nerium oleander ، Conocarpus lancifolins , Eucalyptus camaldulensis Dehnh, Vicia, Jasminum Humile collected from different positions at Nasiriya zone through March to April 2011 were analyzed for heavy metals. The cold extraction method including use of ethanol 95 % , Acetone, petroleum ether, chloroform and cyclohexane .Maximum levels of heavy metals in the analyzed samples were Pb, Cr, Zn ,Cu, and Fe, respectively. Introduction The understanding of fundamental principles and phenomena that control the transfer of trace elements in soil-plant-human chain can contribute to the protection of the environment and human health. Many books, articles, and reports have already described both fundamental and/or detail problems related to these topics.
