Assessment of Water Quality in Coastal Environments of Mohammedia Applying Responses of Biochemical Biomarkers in the Brown Mussel Perna perna
The present work aims to assess the marine environment quality in Mohammedia, using the response of the biochemical biomarkers in the brown mussel Perna perna. The biomarkers selected in this work are : glutathione S-transferase (GST) as phase II enzyme and the acetylcholinesterase (AChE) activity as neurotoxicity marker. The Oxidative stress is evaluated using catalase (CAT), a well-known anti-oxidant enzyme, and malondialdehyde (MDA) accumulation as marker of oxidation of membrane phospholipids through lipid peroxidation. And finally the metallothioneine (MT) as stress proteins.
Our data indicated that CAT, GST activity and MDA, MT concentration in whole mussel bodies, are a higher and significant (p 0.05) in mussels collected at polluted site when compared to specimen sampled from control one.In contrary the response of AChE activity was significantly (p<0.05) inhibited in
mussels from polluted site when compared to control value. The multi-marker results confirm that mussels from Mohammedia have been submitted to polluted environment.
