Effect of 50 Hz, 0.85 mT Magnetic Fields on Total and Differential Leukocytic

Abstract

In current societies, people cannot avoid the exposure to MFs including the ELF-EMF generated by power lines because electricity is widely used and there are various types of electrical appliances. Scientific and public interests in potential health risks related to exposure to ELF-EMF have grown in the last twenty years. Consequently, many cell functions and biological systems may be affected by such risks. Furthermore, the findings of various kinds of human and animal studies which deal with the biological effect of exposure to low frequency EMFs have constantly been both positive and negative. A relationship between subtle bio-effects and exposure to power frequency MFs seems to be shown by few of these studies. To break macromolecular bonds, the extremely frequency electromagnetic field does not have sufficient photon energy. Health could be affected by exposure to ELF-EMFs with subtle bio-effects. Besides, the haematological and immune functions through these mechanisms may be affected by ELF-EMFs. The studies which have investigated the ELF-EMF effects on haematological systems have conflicting results. Therefore, the current study have been carried out in order to estimate the potential effects of in-vivo exposure to extremely frequency electromagnetic fields on the haematological parameters of rats' entire blood. In the current study, the strength of magnetic fields exists in occupational and public environments and is within the limits which comply with the guideline standards of magnetic field exposure in public and occupational environments. Moreover, their intensity is within the range of magnetic fields generated from different electrical appliances.
