Rat hematological parameters of subacute multifrequency electromagnetic next-generation cellular communications exposure
Abstract
The cellular communication electromagnetic fields have become a significant physical environmental factor recently, which cannot but cause reasonable concern due to the possible adverse effects of human health. Experimental laboratory animal studies are an integral part of the development and substantiation maximal permissible levels, in which the blood system is an objective functional indicator of the electromagnetic field biological effects. Thus, the purpose of the research was to study the hematological parameters of the male and female rat blood of subacute multi-frequency electromagnetic exposure from cellular communication systems and possible long-term biological effects. The object of research was male and female Wistar line rats. There were multi-frequency 30-days electromagnetic field exposure with 500 μW/cm2 power density at 3.5, 28 and 37 GHz summary. Hematological parameters of peripheral rat blood of the experimental and control groups were determined at the end of 30 days of exposure and 30 days after exposure. 30 days exposure did not lead to statistically significant changes in the blood cell composition in either male or female rats compared with sham exposure. In post exposure period (30 days after), significant changes in hematological parameters shown female rats only, which consisted in a decrease in the average content (MCH) and the average concentration (MCHC) of hemoglobin (Hb) in erythrocyte (RBC), the level of leukocytes (WBC), lymphocytes (LYM) and an increase in monocytes (MON). There were no statistical changes in all hematological parameters in male rats. The research results suggest the development of aftereffect adaptive reactions in rats upon completion of subacute electromagnetic exposure and their correlation to the effect depending on the sex of the animal.
