The Level of Cd, Hg, Mn and Pb in Sediment and Invertebrate from Northof the Persian Gulf

During present study the concentration of Cd, Hg,Mnand Pb in sediment and Invertebrate of Musa estuary, Hendijan and Bushehr coasts was determine using atomic absorption spectrometer. The results showed that the highest level of Cd, Hg and Mn was observed in Musa estuary sediment and organisms. The maximum concentration of Pb was recorded in Bushehr coast. Musa estuary receives heavy metals from petrochemical units that are established a decade ago in the area, while Bsherhr coastis suffering from huge amounts of tankers traffic and oil transportation in its bank. The correlation between metals level in sediment and Invertebrate showed that there are significant correlation between Hg concentration in sediment and Thalamitaprymna.
