Abstract: As a useful revolution, superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), reduced glutathione (GSH) and lipoperoxidation (as TBARS) in local farming were also determined. This research clear indicated heavy metals accumulation were determined with a higher level. Heavy metals distribution in soils was higher than corresponding background values and significantly related with the accumulation in local farming. The results revealed that heavy metal concentrations were significantly higher than corresponding background values and significantly related to those of the soils. The maximum concentration of potentially toxic elements was observed at the tillering stage, followed by the grain filling stage and heading stage. All the measured biomarkers, including SOD, CAT, POD, GSH and TBARS in the present research, showed obviously different responses compared with that of control site, meaning potential relationship between pollutants stresses and biomarker responses. This study also indicated that the IBR index calculated by combining different biomarkers was coordinated well with the pollutants concentrations.
