Abstract
BackgroundPrevious reports indicate altered metabolism and enzyme kinetics for various organisms, as well as changes of neuronal functions and behaviour of higher animals, when they were exposed to specific combinations of weak static and alternating low frequency electromagnetic fields. Field strengths and frequencies, as well as properties of involved ions were related by a linear equation, known as the formula of ion cyclotron resonance (ICR, abbreviation mentioned first by Liboff). Under certain conditions already a aqueous solution of the amino acid and neurotransmitter glutamate shows this effect.MethodsAn aqueous solution of glutamate was exposed to a combination of a static magnetic field of 40 μT and a sinusoidal electromagnetic magnetic field (EMF) with variable frequency (2–7 Hz) and an amplitude of 50 nT. The electric conductivity and dielectric properties of the solution were investigated by voltammetric techniques in combination with non linear dielectric spectroscopy (NLDS), which allow the examination of the dielectric properties of macromolecules and molecular aggregates in water. The experiments target to elucidate the biological relevance of the observed EMF effect on molecular level.ResultsAn ion cyclotron resonance (ICR) effect of glutamate previously reported by the Fesenko laboratory 1998 could be confirmed. Frequency resolution of the sample currents was possible by NLDS techniques. The spectrum peaks when the conditions for ion cyclotron resonance (ICR) of glutamate are matched. Furthermore, the NLDS spectra are different under ICR- and non-ICR conditions: NLDS measurements with rising control voltages from 100–1100 mV show different courses of the intensities of the low order harmonics, which could possibly indicate "intensity windows". Furthermore, the observed magnetic field effects are pH dependent with a narrow optimum around pH 2.85.ConclusionsData will be discussed in the context with recent published models for the interaction of weak EMF with biological matter including ICR. A medical and health relevant aspect of such sensitive effects might be given insofar, because electromagnetic conditions for it occur at many occasions in our electromagnetic all day environment, concerning ion involvement of different biochemical pathways.
Highlights
Previous reports indicate altered metabolism and enzyme kinetics for various organisms, as well as changes of neuronal functions and behaviour of higher animals, when they were exposed to specific combinations of weak static and alternating low frequency electromagnetic fields
It has been primarily studied in photosynthetic reaction centers and the respiratory chain [7], where triplet yields are modulated by electromagnetic interaction with fields as low as about 50 μT [8]
Exploring Zhadin et al.'s experiment Applying a constant magnetic field of Bdc = 40 μT at pH 2.85 and scanning the alternating magnetic field Bac from 2–7 Hz in steps of 0.05 Hz, a sharp peak was observed at 4.15 Hz
Summary
Previous reports indicate altered metabolism and enzyme kinetics for various organisms, as well as changes of neuronal functions and behaviour of higher animals, when they were exposed to specific combinations of weak static and alternating low frequency electromagnetic fields. The radical pair mechanism is independent of ferromagnetism and has putatively a higher magnetic sensitivity It has been primarily studied in photosynthetic reaction centers and the respiratory chain [7], where triplet yields are modulated by electromagnetic interaction with fields as low as about 50 μT [8]. Already two decades ago effects were described by Blackman et al [9], and later by [10,11,12], which require a combination of static and alternating magnetic fields It turned out, that the magnetic field strength B of the static component and the frequency f of the alternating EMF relate to the "ion cyclotron resonance (ICR) formula":
