 In this rese
In this research, the sediments of Bandar Abbas and Tiab estuary areas in Hormozgan province were conducted to determine the amount of heavy metal contamination (iron, copper, lead, zinc and nickel). Sampling of the sediments of these areas was done to determine the enrichment index and geochemical index using grab, and the flame atomic absorption device was used to determine the concentration of heavy metals. The results based on the mean (M ± SD) shows that the concentrations of the studied elements in different stations were significantly different from each other (P<0.05). So that in terms of the concentration of elements studied by FAO/WHO global standard in Bandar Abbas region (nickel 328.13±139.34, zinc 175.68±50.92, copper 0.0086±0.002, lead 12.67± 81.79 and iron 17520±691.21 μg/g) compared to Tiab region (nickel 1065.56±71, zinc 367.74±23, copper 0227±0.003, lead 72/19±60 123 and iron 35176 ± 872.38 µg/g) exhibited less contamination. The results of the enrichment factor of metals in iron and copper without enrichment, zinc with moderate enrichment, lead with relatively strong enrichment and nickel with severe enrichment, and in terms of Müller's geochemical index, the degree of soil pollution in the category of non-contaminated soils, with nickel component have a moderate degree of pollution. The pollution situation in Tiab region is more severe compared in Bandar Abbas region due to various reasons such as the presence of shrimp breeding sites, urbanization development, industry, agriculture and also due to the unprincipled oil activities that are carried out on the coasts.
