Abstract

U drugoj polovici dvadesetog stoljeća elektromagnetska polja su postala bitna tema mnogih znanstvenih radova iz biomedicinskog područja. Naime, s razvojem tehnologije i globalnom primjenom svih električnih kućanskih uređaja, kao i informatičke opreme, počeo se istraživati utjecaj elektromagnetskih polja na biološke sustave, odnosno organizme. Jedna od glavnih karakteristika koja opisuje elektromagnetsko polje je njegova frekvencija, odnosno odgovarajuća valna duljina. Prema frekvenciji, elektromagnetska polja možemo podijeliti na polja jako niske, srednje i visoke frekvencije. U ovom radu izložen je pregled dosadašnjih istraživanja odgovora organizama na izloženost elektromagnetskim poljima, počevši od prokariotskih organizama. Svi proučavani modeli se razlikuju u odgovoru zbog različite fiziologije, ali su vidljivi utjecaji stresa u svim modelnim organizmima. Premda je utvrđen štetan utjecaj na mnoge organizme, prijetnja vjerojatno ipak nije značajna. Pogotovo za više organizme koji lakše mijenjaju svoj položaj, te nisu trajno izloženi jakim elektromagnetskim poljima.

Abstract (english)

In the second half of 20th century, electromagnetic fields have become the important subject of many research papers in biomedicine. In fact, with technological development and global use of all electrical appliances, as well as informatic equipment,started also research of the electromagnetic fields effects on biological systems. One of the main characteristics which defines electromagnetic field is its frequency or adequate wavelength. We can divide them by their frequency, to extremely low electomagnetic fields (ELF-EMF), intermediate fields (IF) and high or radiofrequency fields (RF). In this seminar paper, a short review of studies of response of organisms on electromagnetic fields exposure, beginning with prokaryotic organisms, has been presented. All research models have different responses because of difference in their physiology, but we can notice stress effects in all model organisms. Although detrimental effects on many organisms were found, an environmental threat is probably not significant. Especially for the higher organisms which can easily change their position and are not permanently exposed to strong electromagnetic fields.
