Cytotoxicity assessment of four pharmaceutical compounds on the zebra mussel (Dreissena polymorpha) haemocytes, gill and digestive gland primary cell cultures

► We apply two simple biomarkers to different zebra mussel cell cultures. ► We test the cytotoxic potential of four therapeutic drugs. ► We find a noteworthy cytotoxicity of diclofenac and gemfibrozil. ► Carbamazepine and atenolol have lower toxicity.
