Abstract
The electromagnetic fields (EMF) effects on water is presently controversial mainly because of variation in water composition and/or environmental conditions. In the present study, we developed new experimental procedures in order to investigate the physicochemical as well as the biological effects of EMF on water. We studied the action of pulsed low frequency electromagnetic fields on the physicochemical properties of water samples prepared under severely controlled conditions. The effect was characterised by using elastic light scattering and photoluminescence: intensities decreased by 25 and 70 % respectively. Our interpretation is (1) that low frequency electromagnetic fields act on the gas/water interface by disturbing the ionic double-layer which stabilises the gas nanobubbles in water (2) that photoluminescence results from the excitation of these hydrated ionic compounds. These results open interesting perspectives in biology. We present preliminary results of germination experiments.
