Biological Effects Due to Hypomagnetic Field and Its Research Progress

Abstract

The biological effects due to hypomagnetic field (HMF) is a very important subject for aerospace travelling and space station living, and a large number of studies on the bioeffects of the HMF have been carried out; however, many essential problems, such as physical mechanism, the harmful for human beings and other living organism of the biological effects, are still remaining unknown. In order to promote the solution to these problems, we assembled, classified and analyzed the studies on the biological effects due to the HMF. About one of the essential problem, i.e. the physical mechanism of the biological effects of HMF, we think that the yield  of the singlet spin state of the radical pair theory, that is) sin sin 4

The Hyperfine Coupling Radical Pair Mechanism of Biological Effects on Weak Magnetic Fields

“…However, the underlying mechanisms remain unclear. In Ouyang and Li [7] the author and his partner gave the point: Equation 1 may be one quantum mechanism of biological effects on a HMF. Ambient alternating fields always exist [73,74] can they influence the biological effects on a HMF ?…”

“…Hypomagnetic field also can be called null or near-null magnetic field [6] .A hypomagnetic field(HMF) or near-null magnetic field is a very important subject for aerospace traveling and space station living [5]. Because of the difference on intensity between GMF(-50uT) and a HMF(<5uT) [5] many effects appear when animals, plants and microorganisms are in the HMF [5][6][7][8][9][10][11][12][13][14][15][16]. For example, a significant increase in anxiety-related behaviors was found when adult male C57BL/6 mice was in short-term HMF for 72h [8].…”

“…Electromagnetic induction,ferrimagnetism and radical pair mechanisms of biological effects of a GMF are introduced [48][49][50][51][52][53][54]. Radical pair and magnetic moment mechanisms of biological effects of a HMF are suggested [7]; [55][56][57]. The mechanisms of biological effects of ELF-MFs which are cyclotron resonance theory and it's new interpretation,the ion parametric resonance model and an interference of ions bound within proteins are proposed [58][59][60][61].…”

The radical pair mechanism of biological effects on hypomagnetic fields and one method to verify it

“…While, Interplanetary space is a natural HMF [2].The range of a HMF is between zero and 5uT [2]. Because of the difference on intensity between GMF(-50uT) and HMF(<5uT) [2] many effects appear when animals, plants and microorganisms are in the HMF [2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Because the HMF is not only a key environmental factor for aerospace traveling and space station living , and but also for some magnetic shielding conditions on the ground, just like, the underground bunkers, the inner chamber of a sub-marine, and the measurement room of magnetoencephalography (MEG) analysis, the biological effect of the HMF should be seriously considered [16].…”
