The technologic development has increased the number of electric and electronic devices for household and work environment applications. In this way, we have to cope with a diverse quantity of electromagnetic irradiation sources, with different power and frequency ranges. For many years, some scientists and engineers believed that low-frequencies electromagnetic field (EMF) could not cause any bad effect or substantial alterations on the biologic livings. This work has the objective to perform a literature review of the possible effects of EMF in human beings and animals, that was published in the past years on Medline, international, and national journals about the EMF (50/60Hz). The results showed that extremely low EMF might produce adverse effects, i.e. cancer, reproduction disruption, degenerative illnesses, citogenetic alterations, and cardiovascular, neurologic and neuroendocrine system alterations in humans and animals. The biologic and biochemical parameters suffered interference as well. Despite all these findings, we can find some disagreements among the authors. Hence it is necessary to extend the research about this issue.
