Abstract

The effect of extremely low-frequency electromagnetic fields (ELF-EMFs) on human health has become a worldwide concern, and no molecule/factor has been established as a measurable indicator of this effect. Diseases related to ELF-EMF are generally accompanied with energy metabolic dysfunction, and the energy in metabolism often flows in terms of electrons in all living cells. Hence, this study specifically investigated the relationship between metabolic current and ELF-EMF. By applying 0-128 Gauss ELF-EMFs to Geobacter sulfurreducens-inoculated bioelectrochemical systems, we found that metabolic current was increased and oscillated in ELF-EMF-exposed G. sulfurreducens. All effects were exposure dose dependent. Moreover, the oscillation amplitude varied linearly with the ELF-EMF strength. These results reveal that metabolic current can be used as a dosimetric indicator of the effect of ELF-EMF on living organisms, including human beings.
