Calcium Ion Flux

by Robert B. Goldberg, Ph.D., Editor

Summary

If EMF has any effect on calcium ion movement across membranes it would have broad implications for cell function. Several papers concerned with EMF effects are reviewed. We start with a work which examined dose-response effects of 50-Hz magnetic field exposures on cytoplasmic calcium ion concentrations in a line of human leukemia cells. Another researcher looked at effects of EMF on calcium ion homeostasis in human hepatoma cells. The results of these two studies are discussed and compared. In a set of published reports, one group showed an EMF bioeffect on the marine diatom Amphora coffeaeformis. The diatom experiment in specific has been repeated by several independent research groups, although the most recent attempt to repeat this in a definitive manner using more sophisticated technology was unable to demonstrate any effect.
