Abstract
This paper presents the Unionidae assemblages from some areas of the Danube Delta Biosphere Reserve. Among the 6 spccics of naiads, the most abundant is Anodonla cygnaea L. 1758, and the most rare is Unio crassus Philipsson, 1758. The adventive species Anodonla woodiana Lea, 1834 is in full process of expansion, being a potential danger for the autochthonous species. The contents of some heavy metals in water, sediments and bivalves (both in soft body and shells) are analysed. Although the mostly researched areas from the DDBR are in pristine ecological conditions, the hydrotechnical works and pollution represent serious dangers for the future. In many cases the most hazardous metals are above safety limits for these organisms.
