“…As a result, a large number of studies were initiated, focusing on the biological effects of a 50-Hz MF with respect to cancer [6–8] and other adverse health effects (e.g. on reproductive [9–11], central nervous system [12, 13], and cardiovascular system health [14, 15]).…”

A 50-Hz magnetic field (MF) is a potential health-risk factor. Its effects on the cardiovascular system have not been fully investigated. This study was conducted to explore the effects of long-term exposure to a 50-Hz MF on the cardiovascular system. In the study, an exposure system was constructed, and the distribution of the 50-Hz MF was determined. Sixty-four Sprague-Dawley (SD) rats were exposed to a 50-Hz MF at 100 μT for 24 weeks, 20 h per day, while another 64 rats were sham exposed. During the exposure, blood pressure was measured every 4 weeks. After 24 weeks, echocardiography, cardiac catheterization and electrocardiography were performed. Moreover, heart and body weight were recorded, and haematoxylin–eosin staining and real-time PCR were conducted. The results showed that compared with the sham group, exposure to a 50-Hz MF did not exert any effects on blood pressure, pulse rate, heart rate or cardiac rhythm. Furthermore, echocardiography and cardiac catheterization showed that there were no significant differences in the cardiac morphology or haemodynamics. In addition, histopathological examination showed that exposure to a 50-Hz MF had no effects on the structure of the heart. Finally, expression of the cardiac hypertrophy–related genes did not show any significant differences between the 50-Hz MF exposure group and the sham group. Taken together, in SD rats, exposure to a 50-Hz/100 μT MF for 24 weeks did not show any obvious effects on the cardiovascular system.

“…RF-EMF is said to have tumor promoting effect as it is being absorbed by tissues regardless of dose exposure [16,27]. Exposure to transient EMF actuated the increase of NO levels, while long haul EMF has a diminishing impact on NO levels in the rodent cerebrum [19]. In human body low level of NO copes abundant physiological capacities.…”

Electromagnetic field (EMF) is a field of combination between electric and magnetic field. While electromagnetic radiation (EMR) can be divided into ionizing and non radiation (NIR). This article review of published scientific studies about NIR and its effect on the human body. From this review, it is found that NIR gives effect towards the human body if it is exposed towards NIR in long time exposure. NIR also creates a thermal effect in long time exposure. This paper tends to create awareness for public that non provide an adverse effect towards public since its source is within our everyday life. For future study, we suggest for a policy to be applied in Malaysia as a basic gui exposure and an implementation of mapping for EMR exposure at East and West of Malaysia to create an easiness for future researcher do a research in the EMR field study.

“…It is well-accepted that EMFs can be generated by a variety of appliances, such as transformers, electrical panels, televisions, and electric blankets (2,3), whose frequency is usually 50-or 60-Hz (4). Human-made EMFs, such as nonionizing radiation, are classified into three categories: extremely low-frequency fields (<300-Hz), high-frequency fields in the radio-frequency band (300-Hz to 3 × 10 8 Hz), and microwaves [3 × 10 8 to 3 × 10 11 Hz; (5)(6)(7)]. Thus, the effects of 50-Hz EMF exposure on human health have attracted more and more attention.…”

Background: Whether electromagnetic field (EMF) exposure affects the function of the cardiovascular system is under debate. The present study aimed to investigate the effects of 500 µT EMF exposure on the cardiovascular system in rats. Methods: Forty-eight-week-old male Sprague-Dawley rats were randomly divided into two groups: the sham group and the exposure group. During 24-week EMF exposure (20 h per day), the blood pressure and pulse rate were recorded every 4 weeks. Before sacrifice, electrocardiography, echocardiography, and cardiac catheterization analysis were conducted to evaluate the cardiac function. Meanwhile, hematoxylin-eosin (HE) staining, Western blot, and real-time polymerase chain reaction (PCR) were performed to identify morphological and molecular changes indicative of cardiac remodeling. Results: The heart rate, blood pressure, and pulse rate were not influenced by EMF exposure compared with the control group. In addition, HE staining showed no change in the morphology and arrangement of cardiomyocytes. Further, we found that the mRNA and protein levels of cardiac hypertrophy-related genes were not affected by EMF exposure. Finally, no significant difference was observed in cardiac function between the two groups by echocardiography and cardiac catheterization detection. Conclusion: The 24-week exposure to EMF at 500 µT did not have apparent effects on the cardiovascular system in rats, at least for the variables studied.
