This paper aims to present a complete picture on the trace metals distribution in the recent mollusk an shells from Lake Qarun sediments. The mollusk an shells were collected during August 2003 and analyzed for the trace metals viz: As, Ba, Cd, Cr, Co, Cu, Fe, Mn. Mo, Ni, Pb, Se, Sr, V and Zn. Their relative order abundance in bivalve shells was: Fe> Cu> Sr> Zn> Mn> Pb> Ni> Se> As> Ba> Cr> Mo> Co>V >Cd, while in gastropod shells was: : Fe> Zn> Mn> Sr> Cu > As > Pb> Se> Ba> Ni>Cr> Mo> Go> V> Cd. The elements were more abundant in gastropod shells. Most elements were associated with aragonite( i.e. nepionic stage) in eastern and middle zone close to the source of the elements and with increasing age( i.e. in adult stage) associated with calcite in western sector. This is due to the mineralogy of shells, secondary alteration, location, environmental parameters, activity of organisms and source of sediments.
