STUDY OF DYNAMICS OF THE WATER REDOX PROPERTIES DURING PROLONGED EXPOSURE IN A HYPOGEOMAGNETIC FIELD

High purity water was a model system to study effects of prolonged exposure in a hypogeomagnetic field (HGMF) on the water redox properties, such as the redox potential, pH value and electric currents. Water samples (40 ml) in glass weighing bottles with ground stoppers were placed for 50 days in a hypogeomagnetic chamber (test). The chamber was a cylinder tube (10 cm in diameter and 50 cm in length) with one end open. The inside walls and bottom were covered with a magnetic field neutralizer – permalloy material. In the center of the chamber the geomagnetic field was weakened in 40 times (~1 mµТ). A similar chamber without the permalloy cover was used for the control. Measurements were made using ionometer I-160МИ once a week at one and the same time. Also, electric currents in water samples were measured continuously. After 50 days, the samples were removed from HGMF and placed in the geomagnetic field in order to study water properties over the next 30 days (recovery period). It was found that after exposure in HGMF the redox potential increased 30 mВ, рН decreased 0.3 and current amplitudes declined by 5 µА. On the background of magnetic storms, all water samples increased the redox potential and рН; current amplitudes reduced in the HGMF water samples. Magnetic storms weakened the effects of HGMF. In the period of recovery, changes in the parameters due to HGMF persisted; conductivity, as well as sensitivity to environmental variations decreased. The acquired water properties can remain over a long time. These results make us think about reactions of the living systems to hypomagnetic fields.
