Sažetak
The objective of the present work was to provide the data on acetylcholinesterase (AChE) activity in the gills of marine mussels Mytilus galloprovincialis from northeastern part of Adriatic Sea. In the first part of the study, range and pattern of AChE activity annual variation was established by monthly investigation of two populations of mussels originating from different natural habitats. No correlation of AChE activity and environmental parameters (temperature, salinity, oxygen) was found. Seasonal monitoring along the coast at sites with presumably different level and type of contamination was also performed in order to study the spatial and temporal trend of AChE activity in mussels, in relation to possible exposure to neurotoxic compounds. Significantly lower enzyme activity in comparison to reference site was recorded at sites in the close vicinity to urban and industrial areas (P and R). In addition, AChE activity decreased at the site within the area of Lim Bay (LI). AChE reduction in the gills of mussels, recorded mostly in the polluted harbours, could be related to the presence of common environmental pollutants. The results obtained in this study will be useful as background data for future biomonitoring surveys along the Adriatic coast using M. galloprovincialis as sentinel organisms.
