in this paper are present the results of measurements of magnetic induction at some locationsin city bor (the east serbia) dating from the household electric devices and transformer stations suited near the residental areas. stress is on the extremely low frequent electromagnetic radiation from transformer stations and other high voltage instalations in urban areas. risk of the extremely low fr...
In this research, the effects of electromagnetic fields of various strengths (0, 1 and 2mT) have been investigated on antioxidant enzymes activity in Valerian (Valeriana officinalis L.). The dry and wet (soaked for 30 min) Valerian seeds were exposed to electromagnetic fields 30 min per day for 3 days. Each treatment and control groups had 3 replicates and 10 seeds were employed for each replic...
Introduction: The highest electromagnetic radiation pollution is related to the radiofrequency waves of mobile phones (1). Up to 70% of these waves can be absorbed by various tissues (2). Absorption of these waves can damage the body tissues by causing oxidative stress (3). Given that melatonin plays an antioxidant role, it seems that this hormone can have a protective effect on the hepato- tox...
background: exposure to extremely low frequency electromagnetic fields is increasingly common, but the potential influence on pregnant women has not been thoroughly investigated. methods: in this case-control study, 58 women who had an unexplained spontaneous abortion at < 14 weeks gestation and 58 matched pregnant women >14 weeks gestation were enrolled in 2012. the women completed the questio...
Background and purpose: Ëffect of electromagnetic filed on the living beings is one of the current issues. With development of technology and increasing application of electromagnetic waves in industry and health affairs, men is exposed to various electromagnetic fields, such as high pressure power cable, radio, ultra magnetic matters, television, mobile and computer. The purpose of this s...
