چکیده انگلیسی
Acetylcholinesterase (AChE) activity is a well established biomarker to monitor environmental pollution caused by neurotoxic compounds, such as organophosphorus and carbamate pesticides. The presence of these compounds results in a measurable inhibition of the enzyme. This has been shown for different marine species including blue mussels. Besides pollution, environmental variables may also have a direct or indirect effect on AChE activity, particularly in estuarine and brackish water environments. To assess the impact of abiotic factors on the AChE activity the seasonal course of gill AChE activity was followed in relation to temperature and salinity in Mytilus sp. collected from the south-western Baltic Sea. In addition, the effect of salinity on AChE activity was investigated in an experimental study. The AChE activity showed significant seasonal differences with maximum activities during the summer period and minimum activities in winter. These changes correlate significantly (p<0.001) and positively with water temperature. The experimental exposure of Mytilus sp. to different salinities (5, 7, 16 or 20 psu) resulted in changes in the gill AChE activity. Empirical orthogonal function (EOF) analysis revealed that AChE activity was significantly and negatively correlated with salinity (p<0.01). These results clearly demonstrate the need to consider the potential influence of temperature and salinity on AChE activity when applying this biomarker to monitor exposure to and effect of neurotoxic substances in estuarine and brackish water blue mussels.
