Abstract :

In recent years, many industries activities such as refining crude oil, aluminum and zinc production, ship repairand construction, loading and unloading of minerals and chemicals, etc. As a development center in BandarAbbas, southern Iran, which formed the subject exacerbate pollution load destruction of sensitive ecosystemscoastal waters region. Therefore, measures to identify and measure heavy metals and trace elements with regardto harmful effects on marine ecosystems including aquatic and consequently affects puts man in sediments ofcoastal waters is an important. Based on this in this study the amount of heavy metals Zn, Cr, Ni and Cd insediments in coastal areas target Bandar Abbas apparatus flame atomic absorption spectroscopy (AAS) wasmeasured. All stages of sample and digestion of sediment according to standard methods (MOOPAM) were.Thus, the average concentration of heavy metals Zn, Cr, Ni and Cd in sediments, respectively 89.1 ± 0.3, 90.4 ±0.3, 27.9 ± 0.3 and 2.1 ± 0.2 (µg g-1) dry weight sediment, respectively. This value with an average concentrationof elements in sediments above and other global internal and external areas were analyzed and compared.Statistical analysis (ANOVA: Single Factor) showed that the average concentration of heavy metals Zn, Cr, Niand Cd in sediment are significant differences between the crossings. Two elements Cd and Zn with a correlationcoefficient of 0.7651 have the highest correlation and then the order of elements Ni and Cr with the coefficientcorrelation 0.7410, Cd and Cr with the coefficient correlation 0.599, Zn and Cr coefficient correlation 0.5603and Ni and Zn with the coefficient correlation 0.1704 are. With coefficient significant and positive correlationbetween Cd and Zn, Cd and Cr, Zn and Cr and finally be determined that the source of pollution in the sedimentsof these elements is the same. The results show there are no statistically significant correlations for Cd, Nicoefficient.
