Abstract

Electromagnetic field of extremely low frequency has an impact on selected chemical components of the honeybee A Koziorowska, J Depciuch, J Białek, I Woś, K Kozioł, S Sadło, B Piechowicz. Electromagnetic field of extremely low frequency has an impact on selected chemical components of the honeybee. Pol J Vet Sci. 2020 Dec;23(4):537-544. doi: 10.24425/pjvs.2020.134703. Abstract The electromagnetic field (EMF) is an environmental factor affecting living organisms. The aim of this study was to demonstrate the effect of an extremely low frequency electromagnetic field (ELF-EMF) on selected chemical components of the honeybee (Apis mellifera L.) using Fourier Transform Infrared (FTIR) spectroscopy. The FTIR method provides information on the chemical structure of compounds through identification and analysis of functional groups. The honeybees were treated with EMF at a frequency of 50 Hz and magnetic induction of 1.6 mT for 2, 6, 12, 24 and 48 hours. Analysis of FTIR spectra showed that EMF exposure longer than 2 hours induced changes in the structure of chemical compounds, especially in the IR region corresponding to DNA, RNA, phospholipids and protein vibrations, compared to control samples (bees not EMF treated). The results confirm the effect of EMF on bees depending on the duration of exposure. pubmed.ncbi.nlm.nih.gov
