Potential use of multixenobiotic defense mechanism (Mxdm) in dreissena polymorpha as a biomarker for the monitoring of freshwater pollution

摘要

Multixenobiotic defense mechanism (MXDM) has been recently described in marine mussels as potential biomarker for the monitoring of water pollution by organic compounds. In this paper, the measurement of MXDM activity was achieved in a freshwater bivalve, dreissena polymorpha. Two methods were tested and compared. The first one (MXDM associated ATPase activity) is an indirect method based on the evaluation of the inorganic phosphate production during MXDM activity.
