Abstract
This study includes ecological survey of soils and natural plants that growing it in three different station . that exposed to the pollution in Kirkuk city . the first station included the lands a rounding the farm located in Dubat quarter, Second station is the lands which located on the side of Al-khassa river at Al-Shuhadaa bridge that exposed to the domestic and commercial pollutants, while the third station includes the lands a rounding the North Oiled Company (NOC) ,in addition to control station behind the party court. Determination of a number of heavy metals ( Cd , Pb , Zn and Fe ) in soil and in common plants among all station as well as control site conducted. Also the estimation of bioconcentration factor BCF for metals conducted to the common plant. The frequency for sample collection was conducted by monthly interval periods , from may 2010 till April 2011 .The results have revealed to high level of Cd , Pb and Fe in second station soil 13.9 ,89.8 , and 8197.6 ppm respectively and high value of Zn in first station soil 335.2 ppm. Also high concentration of heavy metals (Cd , Pb , Zn and Fe ) in soils and plants in studied station in comparison with control site . Observed a high correlation (r = 0.838 ) between soil pb concentration and leave Pb concentration for plants growth in these soil . The heavy metals concentration of soil and plants in the studied sites were higher than the international permissible boundaries. The higher value of Zn 174.14 ppm was for Malva parviflora plant and low value of 94.99 ppm was for P. monspeliensis . The grand range of T. Fe of common plants between all station was 868.18 ppm which higher than normal range .While in respect of BCF , most of common plants between studied site have the ability of accumulation of high amounts of metals in their leaves, among them M. parviflora, Chrozophora tinctoria , Xanthium stramarium and Silybum marianum , this indicated that these plants are preferable species to use as phytoremediation of heavy metals specially Cd , Pb , While M. parviflora and S. marianum benefit to phytoremediation of Zn .
