Publication Abstract: 

Sixteen well preserved Pelecypod and gastropod shells were analyzed for their Mn, Ni, Co, Cu, Zn and Pb content. Eight
shells are belonging to the Pleistocene of Gebel El-Zeit and eight recent shells were collected from El-Zeit Bay. Average
metal accumulation levels in Pleistocene shell of the study area is in the following order Mn< Ni < Cu < Co < Zn <Pb, while in the Recent shell are in the following order Mn< Ni < Co < Zn < Cu <Pb. This is due to the human activities such as: shipping, the oil pollution resulted from the oil industries, where Gabal El Zeit area is one of the important areas of oil
exploration in Egypt. Natural sources of heavy metals include: terrigenous inputs from wadis during flash floods that
transport terrestrial material into the sea.
