Preliminary Assessment of Stress and Genotoxicity Biomarkers in Bivalve Molluscs from the Gulf of Annaba, Algeria

The aim of this work is to assess biomarker responses to stresses caused by pollution of the marine environment in the Gulf of Annaba, using the bivalve mollusc Donax trunculus and Mytilus galloprovincialis . Males and females were collected during the summer from site 1 considered to be far from po...

Description
Summary:The aim of this work is to assess biomarker responses to stresses caused by pollution of the marine environment in the Gulf of Annaba, using the bivalve mollusc Donax trunculus and Mytilus galloprovincialis . Males and females were collected during the summer from site 1 considered to be far from pollution sources (SM1 and SD1), site 2 (SM2 and SD2) exposed to a mixture of contaminants, and site 3 (SM3 and SD3) receiving the untreated sewage. The whole body was used for the determination of malonaldehyde (MDA), reduced glutathione (GSH) and DNA damage. The MDA concentration from site 2 of both species has indicated significant augmentation. The two bivalves from S2 and S3 have recorded significant decrease of GSH level, with the highest number of Comet scores. A significant site and sex effect was measured for the level of GSH and MDA, accompanied with a significant site effect for DNA damage. The genotoxicity seems correlated with the stress biomarkers and dependent on the effluent types.
