In generally, in this survey 9 samples of parsley and 9 samples of soil was evaluated. Samples was digested in laboratory by using of acidic digestion. Then concentration of elements was read by using of atomic publication machinery and for analysis of datas, was used version 19 of SPSS (α=0/05). Results: Average concentration of cadmium, nickel, lead and zinc in parsley vegetable is in the order of 1/14, 2/56, 16/65 and 25/23 mg/kg and average concentration of this metals in soil is in the order of 0/23, 23/51, 20/85 and 57/5 mg/kg. Results of this study showed that average concentration of Cadmium and Leadin parsley is above WHO/FAO whereas average concentration of Nickel and Zink in parsleywas assessed less than WHO/FAO. Also the average concentration of every four metals in soil of farms was less than WHO/FAO levels.On the other hand the amount of risk and health index (HRI) in parsley for lead metal was above 1 and for cadmium, nickel and zinc metals was less than 1. Conclusion: According to the studing results, cultivated parsley in this area was polluted to the heavy metalsCadmium and Lead, and the results indicates the very easy transferring of this metals from soil to parsley that was not healthy for human daily consumption and risk and health index (HRI) that was above 1 for lead metal shows the hygienic potential risk of this metal in relation to the polluted parsley consumption in human daily alimentary diet.
