Background and Objective: Evaluation of pollution in the port of Deylam and assessment Risks of environmental pollution Taking the position of the port and And direct contact People with the sea ‚this port is very important.Material and Methodology: In this study sediments samples were collected from 5 stations along coast. After drying and digesting of samples in Nitric acid and Perchloric acid, concentrations of heavy metals were measured by Atomic Absorption Spectrophotometer (AAS).Finding: The results of this study have shown that the levels of heavy metals in sediments of stations based on micrograms per gram dry weight of 2/1-6/40 Cu, 10/4-21/18Pb-1/1-2/8for Cd. between stations surveyed in the study In seaside Park station had the lowest pollution by metals. Bandar Imam hasan and Bandar Lyltyn Stations had the highest rate of pollution of these metals.Discussion and Conclusion: Comparison rate of these metals with international standards showed that the concentration of Cu and Pb concentrations is below international standards, but the amount of these metals was higher than USEPA standards. And the amount of cadmium is more from the standard USEPA, sediment quality US (NOAA) and sediment quality in Canada (ISQGS).
