Sediments act as indicators of heavy metal in coastal environment, they are the main reservoir of heavy metals. Inorder study about environmental pollution and the andemic species, sediments and T. mutabilis samples were collected from 5 transects (South Golshahr, Khaje Ata, Posht-e- shahr, Jahanbar rahe Se, Soro) of the Bandar Abbas (NE Persian Gulf) in cold and warm season, and the metal concentrations were determined for them. Metals contents were analyzed by using ICP-MS. Statistical analysis was performed with SPSS 18.0 software. The highest amount of metals belongs to Fe, Al, Mn in warm and cold season. Sediment quality was measured by Contamination Factor. Cd, As, Hg, Zn, Cu & Pb levels in sediments from all transects higher than the recommended values of standard (USEPA ,1996; ROPME, 2003).
