[Analysis of pro/antioxidant properties of water and water solutions].

The ability of water preparations of different composition to affect the generation of superoxide radicals has been compared. The superoxygenating reaction of adrenaline autoxidation with some modifications was used as a model system, which makes it possible to reveal the pro/antioxidant properties of materials being tested. It was shown that samples of water from sources having different specific electroconductivity and, accordingly, ionic composition differ in the ability to affect reactions proceeding with the participation of ROS. The parameter measured, the pro/antioxidant activity of water, is a new informative indicator, and the approach proposed enables one to perform a comparative estimation of the quality of water and aqueous solutions.
