Interaction of static and extremely low frequency electric and magnetic fields with living systems: health effects and research needs.
TLDR
Although health hazards exist from exposure to ELF fields at high field strengths, the literature does not establish that health hazards are associated with exposure to low-level fields, including environmental levels, and so no further research in this area was deemed necessary.Abstract:
An international seminar was held June 4-6, 1997, on the biological effects and related health hazards of ambient or environmental static and extremely low frequency (ELF) electric and magnetic fields (0-300 Hz). It was cosponsored by the World Health Organization (WHO), the International Commission on Non-Ionizing Radiation Protection (ICNIRP), the German, Japanese, and Swiss governments. Speakers provided overviews of the scientific literature that were discussed by participants of the meeting. Subsequently, expert working groups formulated this report, which evaluates possible health effects from exposure to static and ELF electric and magnetic fields and identifies gaps in knowledge requiring more research to improve health risk assessments. The working groups concluded that, although health hazards exist from exposure to ELF fields at high field strengths, the literature does not establish that health hazards are associated with exposure to low-level fields, including environmental levels. Similarly, exposure to static electric fields at levels currently found in the living and working environment or acute exposure to static magnetic fields at flux densities below 2 T, were not found to have demonstrated adverse health consequences. However, reports of biological effects from low-level ELF-field exposure and chronic exposure to static magnetic fields were identified that need replication and further study for WHO to assess any possible health consequences. Ambient static electric fields have not been reported to cause any direct adverse health effects, and so no further research in this area was deemed necessary.read more

Review of the epidemiologic literature on EMF and Health.
TL;DR: Evidence shows an association of amyotrophic lateral sclerosis with occupational EMF exposure although confounding is a potential explanation and further studies need to be designed to test specific hypotheses such as aspects of selection bias or exposure.

TL;DR: It is shown that by extending the duration of exposure to TTFields, slowly dividing cells can be affected to a similar extent as rapidly dividing cells.

TL;DR: It is concluded that a strong SMF has the potency not only to stimulate bone formation, but also to regulate its orientation in both in vitro and in vivo models, and is the first study to show the regulation of the orientation of adherent cells by a magnetic field.

Bioeffects of static magnetic fields: oxidative stress, genotoxic effects, and cancer studies.
TL;DR: This review focuses on the own data and other data from the literature of SMFs bioeffects, which suggests that cell proliferation can be influenced by a treatment with both SMFs and anticancer drugs.

Case-control study of childhood cancer and exposure to 60-hz magnetic fields
TL;DR: The results encourage further examination of the carcinogenic potential from this form of nonionizing radiation, and are nonresponse, differential mobility of cases and controls, and a presumably nondifferential exposure misclassification from the use of imperfect surrogates for long-term magnetic field exposure history.

Magnetite biomineralization in the human brain.
TL;DR: Biogenic magnetite in the human brain may account for high-field saturation effects observed in the T1 and T2 values of magnetic resonance imaging and, perhaps, for a variety of biological effects of low-frequency magnetic fields.
