  Abstract:  The aim of our study was to distinguish the activity of some enzymes along the course of the Arieş River to understanding the complex processes that happen in these habitats of special significance. The sediment samples from different points on the Arieş River (Abrud, Baia de Arieş, Sălciua, Turda, Luncani) have been taken seasonally during the year 2007. In the sediment samples the following enzymatic activities have been quantitatively determined: phosphatase, actual and potential dehydrogenase and catalase. Based on the relative values for the enzymatic activities, the enzymatic indicator of the sediment quality (EIQS) was also calculated.
