Genotoxic and cytotoxic effects of 50 Hz 1 mT electromagnetic field on larval rainbow trout (Oncorhynchus mykiss), Baltic clam (Limecola balthica) and common ragworm (Hediste diversicolor).

•Genotoxicity and cytotoxicity responses in aquatic animals exposed to 50 Hz 1 m T electromagnetic field (EMF) were assessed.•Nuclear lesions in erythrocytes of O. mykiss, coelomocytes of H. diversicolor and gills cells of L. balthica were assessed.•Genotoxic and cytotoxic activity of 1 m T EMF in O. mykiss and L. balthica was revealed.•Genotoxic activity of 1 m T EMF in H. diversicolor was revealed.•Submarine cables that are present in the natural aquatic environment may pose threat to those organisms.
