The polychaete annelids (family nereidae) are abundant in intertidal zone. These animals have potential to accumulate and tolerate some toxic metals in their tissues. In the present study, the four heavy metals; Mn, Pb, Cd and Cu in the whole body of the polychaete worm Nereis succinea sampled from two areas were measured. The concentration of heavy metals determined for individuals inhabited both studied sites has confirmed the potential of the selected worm to accumulate heavy metals from ambient habitat. On the other hand, histopathological investigations have clarified that the granular deposition of heavy metals within tissues of N. succinea was related to the degree of heavy metals loads from site to another.
