Concerns about the effects of electromagnetic radiation on the human body have increased due to advances in and ever-greater use of communication devices. The biological effects of exposure to electromagnetic fields (EMF) are currently a popular subject for researchers. EMF exposure is reported to cause various effects on the human body. However, it is unclear whether these effects cause any adverse physical outcomes. How organisms are affected by this growing worldwide mobile phone use is an important question, and several scientific studies have been performed in order to investigate this.

Numerous devices are known to emit EMF, such as communication equipment, substations, mobile phone base stations, radio and television transmitters, electrical equipment at home and work, and high voltage lines, in addition to the many electrical systems in the environment. However, while life is made considerably easier by these devices, they may also have deleterious effects on health. Mobile phones are now starting to be used at elementary school age, meaning that lifetime exposure to EMF is increasing. Studies have shown that symptoms such as stress, headache, fatigue, anxiety, decreased learning potential, impairment in cognitive functions and poor concentration may occur due to exposure to microwave radiation emitted by mobile phones. Several metabolic processes and mechanisms in the organism are also affected by EMF exposure. The body's chemical integrity may be damaged by EMF exposure due to the fact that high electromagnetic absorption is capable of altering the electrical current in the body. Different parameters have recently been used to assess the biological effects of in vivo and in vitro exposure to non-ionizing radiation in animals, humans and cells. Unbiased evaluation of the beneficial or hazardous effects of EMF exposure from various different viewpoints using ultrastructural and morphological approaches is now required. The main goal of this special issue is to shed light on this subject.

Kıvrak et al.’s review reports the effects of oxidative stress on antioxidant systems and suggests that EMF may cause oxidative stress in several tissues. The authors report that various antioxidants can be used to prevent the potential damage resulting from EMF exposure.

Warille et al.’s review discusses the enzymatic and hormonal changes occurring during EMF exposure and the underlying cellular mechanisms. The mechanism of these effects may differ, depending on the intensity of magnetism. The authors suggest that more studies involving experimental and epidemiological characteristics and focusing on the deleterious effects of EMF exposure on enzymatic and hormonal mechanisms are now required.

Kocaman et al. focus on the protective effects of omega-3 on the rat adrenal gland exposed to 900-MHz EMF. The authors report that omega-3 treatment reduces the side-effects of EMF exposure in the rat kidney.

Deniz et al. investigate the effects of mobile phones, not only on the morphology of the human brain but also on cognitive performance using stereological and spectroscopic methods and neurocognitive tests. Their results indicate that subjects who talk on mobile phones for prolonged periods during the day display low concentration and attention.

Another study by Deniz et al. reports that the oxidative damage exerted by electromagnetic radiation emitted by cell phones in the rat kidney is ameliorated by folic acid. That study used stereological techniques to evaluate glomeruli numbers as well as kidney volume.

Etet et al. report that high illuminance visible electromagnetic radiation leads to various changes in the functions of the brain and general health in mice, which are partially mediated by damage to the neocortex-entorhinal cortex-hippocampus axis. These findings suggest a need for caution in the use of high illuminance artificial light for extended periods.

Kıvrak et al.’s paper reveals the effects of 900-MHz EMF emitted by mobile phones on Ammon's horn and the dentate gyrus in the hippocampus and cerebellum of male Wistar albino rats. The authors also investigate the neuroprotective effects of antioxidants such as Boswellia sacra and folic acid against the side-effects of EMF exposure. The stereological and histological results of this study indicate that EMF exposure causes deleterious effects on the cells of the hippocampus and cerebellum. Boswellia sacra and folic acid were observed to exhibit protective effects in the cells of the hippocampus and cerebellum against exposure to 900-MHz EMF.

Chandel et al. focus on the role of cell phone electromagnetic field radiations (EMF-r) in inciting oxidative damage in onion (Allium cepa) roots at a frequency of 2100 MHz. Their study suggests that onion roots undergo abiotic stress caused by EMF-r and that this induces oxidative damage in the plants.

Altun et al. report the effects of pulsed digital electromagnetic radiation emitted by mobile phones on the central nervous system of the adult Wistar albino rats. That study found neuroprotective effects of melatonin (Mel) and omega-3 (ω3) based on the antioxidant defence system.

We would like to express our particular gratitude to all the authors for their excellent submissions to this special issue. We also express our sincere thanks to the invaluable reviewers from all around the globe who gave their precious time to review the submitted papers. We are especially grateful for their rapid responses throughout the reviewing process. Finally, our profound thanks to Editor-in-Chief Prof. Abdulmoneam Al-Hayani and his team for their vital editorial support in the production of this special issue.
