Purpose: To analyze the results of direct and transgenerational effects of radio frequency electromagnetic fields (RF-EMF) on the model organism of crustaceans .
Materials And Methods: were chronically exposed at 900 GHz EMF with an energy flux density (EFD) of about 1 mW/cm in the juvenile and pubertal periods of their ontogenesis. The cytotoxicity of exposure as well as survival, fertility and teratogenic effect of directly exposed daphnids and their progeny across three generations were analyzed.
