Systematic review on the biological effects of electric, magnetic and electromagnetic fields in the intermediate frequency range (300 Hz to 1 MHz)

Objective: Recent technological advances have exponentially expanded globally; harbouring upon Electromagnetic fields (EMF). The utilization of Electromagnetic field has become universal from everyday usage of electronic appliances such as micro wave ovens, tablets and portable computers to telecommunication systems mobile phone towers, radio- television broadcast systems and electronic power transmission systems resulting in electromagnetic field and associated radiations. EMF can have biological effects on cell at microlevel and have the potential ability to cause cell dysfunction manifesting in various biological effects. This review tried to gather evidence from the existing literature about the biological effects of EMF on human health. Materials and Methods: We did extensive literature search using PubMed and Cochrane database using key words, “electromagnetic fields”, “Extremely low frequency electromagnetic fields (ELF-EMFs)”, “biological effects”, “health effects”, “public health”. We included 20 studies conducted from Dec 2009 to Dec 2019 in our systematic review. Data from each study was extracted by two independent researchers and discrepancies were resolved by consensus. Results: Significant biological effects of EMF exposure were reported on human health ranging from anxiety, depression, sleep disturbance, increased risk of Alzheimer’s disease and ALS (Amyotrophic Lateral Sclerosis), hypersensitivity to infertility and increased risk of multiple carcinomas. Conclusion: Application of preventive measures in order to minimize the exposure becomes the need of the hour especially so in occupational settings.

Electromagnetic property of biological tissue is a critical issue for studying the biological effects of electromagnetic fields. In order to investigate the electrical parameters of rat blood and dispersion spectrum within the low-frequency, dielectric and conductivity parameters of rat blood was measured via HP4275A Multi Frequency LCR Meter in low frequency range (10 kHz-10 MHz), dispersive characteristics of blood electrical parameters was defined within the low-frequency. Dielectric properties of the measurement were used to compare with the theory of Cole-Cole fitting, and the fitting result shows that the Cole-Cole theory can well reflect the dielectric dispersion characteristics of rat blood. These results can be used to studying further biological effects of different frequencies electromagnetic fields.

Different Levels

Despite the fact that there are still conflicting opinions about the damage caused by modern wireless communication technologies, most scientists report on the negative biological effects of low-intensity radio frequency electromagnetic radiation at different levels of the organization of live nature. There is no doubt that there is a need not only for a sanitary and hygienic assessment of man-made electromagnetic effects on humans, but also for an environmental assessment for biota. The purpose of the study was to assess the potential environmental risk of electromagnetic impact in the centimeter range on natural ecosystems. The initial data were the authors' own results in the field of radiobiology of non-ionizing radiation, as well as published of other researchers. The article analyzes the biological effects of radio frequency electromagnetic fields detected in organisms of different systematic groups and levels of organization. The data on the non-thermal biological effects of electromagnetic fields indicate a high sensitivity of different species to this factor. The analyzed research results emphasize the need to take into account the features of non-thermal effects of electromagnetic radiation on biota, since these radiations can have a negative impact on different hierarchical levels in natural ecosystems.
