This study was conducted in the winter of 2011 at Yard Pars Steel Ship near Bandar Abbas, Hormozgan province, to determine the amount of heavy metal (iron, copper, lead and nickel) contamination in the sediment of the area in order to investigate the impact of the ship recycling industry on the sediment. Has found. Based on the results, the maximum iron content in the sediment was measured at 2.2402 ppb at the ship's recycling station (station b). Similarly, the highest mean copper in sediment was estimated to be 34.37 ppb and 0.32 ppb in station b. Nickel content was 0.18 ppb (in station c 300 m from station b). All concentrations were below the epa standard. According to one-way ANOVA test, there was a significant difference (at 95% confidence level) between the concentrations of Fe, Cu and Pb in sediment of station b (main scrub site) with other stations. There was also a significant difference between the concentration of nickel in sediment of station c with stations a, b, d and e (p <5%) According to the results of the present study, heavy metals of iron, copper, lead and nickel They are released at the ship's recycling site. Although all concentrations are below the EPA standard, this study demonstrates the importance of the impact of such activities on the environment, possibly due to the limited activity of the ship's vessels in the area.
