Comment on "Constraints on biological effects of weak extremely-low-frequency electromagnetic fields"

Biological effects of low frequency electromagnetic fields.

Epidemiological studies since 1979 have raised some medical and much public concern that low frequency electromagnetic fields, such as those of power-lines and in domestic and industrial electrical wiring, may have harmful biological effects. These studies are generally inconsistent, inconclusive, and difficult to replicate. Identifying biological mechanisms by which such harmful effects may oc...

Effect of occupational exposure to extremely low frequency electromagnetic fields on level of thyroid hormones effective on fatigue

Background: The aim of this study was to assess exposure to extremely low frequency electromagnetic fields (ELF-EMFs) and its effects on secretion of thyroid hormones associated with symptoms of fatigue on electric arc welding workers. Methods: This study was carried out on two groups including 35 welders (as exposed) and 35 non-welders (as control). Extremely low frequency electromagnetic fie...

assessment of the effects of extremely low frequency electromagnetic fields on toxoplasma gondii

background: the effects of extremely low frequency electromagnetic fields (elf-emf) on toxoplasma gondii have not been explained yet. the aim of this study was to assess the possible effects of elf-emf on growth, survival time and viability of toxoplasma gondii . in addition, the life span of toxoplasma infected animals was investigated. methods: sixty adult male balb/c mice were used for in vi...

Diatom motility: the search for independent replication of biological effects of extremely low-frequency electromagnetic fields.

PURPOSE To investigate the hypothesis that exposure to a certain combination of static and time-varying electromagnetic fields (EMF) results in an increase in motility of the marine diatom Amphora coffeaeformis. MATERIALS AND METHODS Diatom motility on agar was positively correlated with calcium ion (Ca2+) concentration. In previous experiments extremely low frequency EMF (16 Hz) had the grea...
