The date clam, Lithophaga lithophaga is a popular edible bivalve. It was collected from three different locations (Abo-Quir, Miami and El-Mex) along the coast of Alexandria-Egypt to determine the effect of two heavy metals as copper (Cu) and cadmium (Cd). The three organs were selected: gill, mantle and digestive gland. The enzymatic change is correlated with the concentration of metals. The present results suggest that Miami water is less polluted with Cu and Cd as compared to the two other locations. The physicochemical parameters are not significant among the three locations. Water of Abu-Quir and El-Max may be hazardous to bivalves. The order of levels of Cu and Cd was: gill > digestive gland > mantle. The present study illustrated that, in Abu Quir, there was a high positive correlation between Cd and Succinate dehydrogenase (SDH) as r = 0.969 whereas Cu and SDH as r = -0.91.
