Effects of concurrent exposure to 60 Hz electric and magnetic fields on the social behavior of baboons

Abstract

Our previous research has demonstrated that 30 or 60 kV/m electric fields (EF) reliably produce temporary increases in the performance of three categories of baboon social behavior: Passive Affinity, Tension, and Stereotypy. The experimental design included 6 week preexposure, exposure, and postexposure periods with experimental and control groups, each with eight subjects. Here, we report two experiments that evaluated the effects of combined EF and magnetic fields (MF) on baboon social behavior. One experiment demonstrated that exposure to 6 kV/m EF and 50 microT (0.5 G) MF produced Period x Group interactions for Stereotypy and Attack, but the previously observed increases in Passive Affinity, Tension, and Stereotypy did not occur. A second experiment demonstrated that exposure to 30 kV/m EF and 100 microT 1.0 G MF did not produce the same magnitude of increases in Passive Affinity, Tension, and Stereotypy observed previously with 30 kV/m EF alone. The exposed group exhibited decreased performance rates for several behavior categories during exposure with further declines during postexposure. The control group showed fewer downward trends across periods.

•The effects of electromagnetic field exposure at short and long term of 900 mhz frequency emitted from mobile phones on rat bone tissue

“…As cellular phone usage gets more widespread, electromagnetic radiation has become an important health problem, which was also reported by the previous studies suggesting the harmful effects of radiofrequency waves on human health. [1][2][3][4][5][6][7][8][9][10] So far, there has been a controversy whether EMF has a negative effect on health or not. Previous studies have shown that high frequency EMF emitted from mobile phone mostly interacts with the auditory, endocrine and nervous systems.…”

“…[5][6][7]22 In addition to there are some studies have deal with effects on reproduction and development. 3,4,23 However, not only the potential side effects for these are of interest, but also potential side effects to the other systems are of importance. It is supposed that mechanisms involved in this process are related with heat at high frequency and chemical changes at low frequency.…”

“…There are increase number of evidence that exposure to the radiofrequency fields from mobile telephones or their base station could affect human health. [1][2][3][4][5][6][7] The bone is a potential route for the absorption of hazardous materials in the environment. 8,9 The low-frequency electromagnetic fields (LFEMF) have some biological effects on the behavior of the cell populations of bone.…”

The Effects of Electromagnetic Fields on the Ultrastructure of Heart

“…An increased health risk due to exposure to electromagnetic fields (EMF) at 50 and 60 Hz has been reported by several authors (Zecca et al,1998;Seegal et al, 1989;Coelho et al, 1995;Svedenstål & Johanson, 1995). In vivo studies have dealt with increased tumor incidence, effects on reproduction and development, and neural and behavioral changes (Zecca et al).…”

The effect of extremely low frequency magnetic field on heart tissue iron density

“…An increased health risk due to exposure to electromagnetic fields (EMF) at 50 and 60 Hz has been reported by several authors. [1][2][3][4] Iron is an essential element in a variety of vital processes, including respiratory electron transfer, oxygen transport. 5 However, when iron reacts with H 2 O 2 , hydroxyl radicals are produced via a Fentontype reaction.…”
