“…Similar phenomena have been reported in many aquatic organisms previously. For example, studies showed that, the lysozyme level significantly decreased, and the AST and ALT levels significantly increased upon magnetic field exposure in Cyprinus Carpio ( Khoshroo et al, 2018 ) and Caspian kutum ( Loghmannia et al, 2015 ).…”

Artificial magnetic fields are unavoidable environment for offshore marine organisms. With the substantially increasing submarine cables, the impact of magnetic field generated by cables on marine organisms has gradually attracted people’s attention. However, there are few studies on the effect of magnetic field on molluscs. To explore whether magnetic fields could interfere with the physiological functions of offshore molluscs, here we systematically analyzed the change of metabolism and transcriptome of Elysia leucolegnote exposed to either geomagnetic field or 1.1 T static magnetic field. The blood glucose and lipid levels, as well as the activities of antioxidant enzymes in E. leucolegnote were significantly increased upon the exposure to high static magnetic field for 10 days. Meanwhile, the activities of enzymes related to digestive performance and liver functions were decreased. Possible mechanisms were further revealed through comparative transcriptome analysis. A total of 836 differentially expressed genes were identified, 352 of which were up-regulated and 484 of which were down-regulated after exposure to the high static magnetic field. The up-regulated differential genes were mainly concentrated in lysosomal and apoptotic pathways, and down-regulated differential genes were mainly involved in digestive and immune systems including phagocytosis. This pattern was further confirmed by RT-qPCR analysis. In conclusion, prolonged exposure to a 1.1 T static magnetic field increased oxidative stress and blood glucose and lipid levels, and decreased immunity and physiological conditions in E. leucolegnote. The data we presented here provides a comprehensive view of metabolism change and gene expression pattern of E. leucolegnote exposed to static magnetic field. It may expand our knowledge on the magnetic field effects on offshore mollusc at molecular level, and contribute to clarification of the interaction between marine animals and artificial magnetic fields, which is certainly ecologically important.

“…Because IMF-MFs is 300 Hz through 100KHz or10 MHz [2]; [64] ELF-MFs is 0Hz through 300Hz and the author thinks ELF-MFs may be regarded as static and corresponding effects can be explained through Equation 2 in part 3.4, and one band of IMF-MFs (near ELF-Mfs) may be regarded as static and can be explained through Equation 2 just like the case of ELF-MFs.…”

“…Since at least the late 1950s, the public have raised the concerns about the potential biological effects of nonionizing radiation [1]. According to the European Commission, non-ionizing radiation are divided into static magnetic fields (0 Hz),extremely low-frequency (0 to 300 Hz), intermediate frequency (300 Hz to 100 kHz), and radio frequency (100 kHz to 300 GHz) fields [2].…”

More recent concerns have been raised about the biological effects of all different weak magnetic fields (MFs) with the development of electric device era and information era. The biological effects due to weak MFs just like a hypomagnetic field (HMF) or near-null magnetic field is a very important subject for aerospace traveling and space station living. A large number of studies on the biological effects of other weak MFs have been carried out. The biological effects of different weak MFs can be negative or positive. Many mechanisms to explain the bioeffects of weak MFs have been given. Are there possible common mechanisms of the different biological effects in different weak MFs ? It's unbelievable and sound impossible at first sight that different bioeffects of different weak MFs have common mechanisms. But possible common mechanisms can exist. In this study, the author proposes the relations between the singlet yield of the radical pair and the weak MFs are the possible common mechanisms. Giving one possible common mechanism of bioeffects of all different weak MFs including impulsed ones is the first to the author's known. Here, the weak MFs are ones that cannot produce thermal bioeffects not only limited below 1mT.
