Chromium Ion Uptaken from Soil through Phytoremediation Using Zea Mays and Nicotiana Tabacum

Abstract

Green technology “phytoremediation” approach was applied in WadiA lsamin in Hebron-Palestine to evaluate the plant efficiency in remediation of soil that is polluted with chromium (Cr). An open field controlled experiment was conducted to assess the efficiency of two plant species, namely corn (Zea mays) and tobacco (Nicotiana tabacum), in remediating the Cr-polluted soil. The concentration of Cr metal was determined in all plant parts (root, stem, leaf and fruit) for both plants using ICP-AES. The accumulation of Cr was higher in leaves than in the other plant parts for both plants with order of leaf>stem>root>fruit for corn plant and leaf>stem>fruit>root for tobacco.
