<p>Under the greenhouse scale, nano zero valent iron (nZVI) have been evaluated by formulation with carboxymethyl cellulose (CMC-nZVI), chitosan (Ch-nZVI), biochar (BC-nZVI), and smectite (SC-nZVI) at rates of 0 0.5 1% (w/w). The properties manufactured compounds their impact on soil ecosystem planted safflower (Carthamus tinctorius L.) as a phytoremediation crop for inorganic contaminants in contaminated mining soils measured. After 33 days, growth parameters were recorded harvested plants concentrations some HMs plant tissues. Furthermore, pH, EC, soluble Na available Cd, Cu, Pb Zn treated after harvest analyzed. Results revealed that Ch-nZVI SC-nZVI application 0.5% led to narrow non-significant increase dry biomass shoot length compared control. On other hand, CMC-nZVI BC-nZVI resulted reduced growth. All applied amendments increased contents. synthesized nZVI composites showed considerable (non-significant) heavy metals Application CMC-nZVI1% copper (Cu) zinc (Zn) (182% 114%, respectively, control), while Ch-nZVI, 1%, BC-nZVI0 5% reduce Zn, roots 65.2%, 31.4% 85.5% respectively control). indices uptake extraction weren't significant decreasing polluted materials disabled actions hyperaccumulated used. these didn’t effect immobilize soil, SC-nZVI, reducing Pb, Zn. It could be concluded might restricted, mainly due negative impacts besides side effects test crop.</p>
