Abstract In the first experiment based on pedologic and geomorphic characteristic of Pband Zn mines Anguran mine in Zanjan province Bama mine in Isfahan province andSormeh mine in Fars province were selected The soils derived from mine parentmaterials were studied in a detailed scale The research sites were selected based on theobtained data The soil and plant samples were collected from natural metal pollutedsoils The concentration of Pb and Zn were measured in the collected sampled UptakeIndex was calculated both for pb and Zn The highest amount of Zn Uptake indexobtained for stipa barbata where the maximum Pb Uptake index obtained for Kochiascoparia In the second experiment phytoextraction of Lactuca sativa Spinaciaolereacea Brassica oleracea Beta vulgaris Lolium persicum Bromus beneckenii Secale Zea mays Helianthus annuus and brassica napus were investigated in a potexperiment The treatments were two levels of chelation agents 1 5 and 3 0 mmolesDTPA per kilogram of dry soil two levels of sulfuric acid 0 5 and 1 mmole sulfuricacid per kilogram of dry soil two levels of composted manure 7 5 and 15g ofcomposted manure per kilogram of dry soil and control The experiment was conductedin a factorial arrangement based on completely randomized block design with 3replications in greenhouse The results showed that DTPA sulfuric acid and compostedmanure treatments increased the availibility of soil Pb and Zn The treatments alsoinereased the concentration of metals in the shoot and root of studied plants but not withthe same pattern In addition Zea mays and Helianthus annuus showed the maximumpotential for Zn extraction where Lactuca sativa and Lolium persicum showed themaximum removal potential of Pb from studied soil In the third experiment hydratedzinc sulphate ZnSo4 7H2O was activated in Isfahan Miniator Neutron SourceReactor Activated zinc 65Zn was mixed with a virgin soil by a rate of 0 control 20 100 and 200 mg per kilogram of dry soil The seed of Zea mays were sown in treatedpots based on completely randomized block design with 4 replications The resultsshowed that by addition of different levels of 65Zn root stem and leaf dry biomass ofZea mays did not increase The concentration of 65Zn in different part of Zea maystissues increase as the dose of 65Zn application increased The soil samples werecollected in three stages Initial sampling after 4 weeks incubation and afterharvesting Sequential extraction of the second stage samples showed exchangeable Znfraction Zn bound to organic matter and Zn bound to Fe and Mn oxides were increasedwhile sequential extraction of the third stage samples showed a decrease inexchangeable Zn fraction Zn bound to organic matter and an increase in Zn bound tocarbonate and residual fraction Keywords phytoextraction heavy metals hyper accumulation sequential extraction activated Zn 65Zn
