Vast oil fields of Ahvaz City located in southern Iran are known as one of controversial subjects in contamination with heavy metals. In this study, oil fields' soils of Ahvaz city (Ab-Teymour) were chemically analyzed in order to determine the concentration of eight heavy elements (Cu, Ni, V, Co, Cd, Zn, Mo and Pb) and intensity of contamination. The area was divided into 12 plots with respect to proximity to drilled oil wells as well as the existing flares. The results show that concentration of studied metals is higher than earth’s crust mean values. According to Muller’s geochemical index, intensity of contamination varies from unpolluted to highly polluted ones. These highly polluted areas require methods such as phytoremediation more than ever. By comparing list of local plants with that of heavy metals absorbing plants and given the local climate, a suitable absorbing plant for each of the existing heavy metals was recommended.  UR - https://www.gjesm.net/article_14054.html L1 - https://www.gjesm.net/article_14054_6e5a2e56afc968d08ed2f6e470947a4f.pdf ER -
