Figure 5: Migration of hydrogen from hydrogen-water in various containers into the atmosphere. Note: (A) Various hydrogen-water containers made by polyethylene (PE), polyethylene terephthalate (PET), polypropylene (PP), glass, aluminum and stainless steel, were used to measure migration of hydrogen. (B) Change of dissolved hydrogen concentrations (DH) by standing times. Hydrogen-water of 150 mL having hydrogen of 830 μg/L at 20°C was placed in each container and left to stand. (C) Change of oxidation-reduction potential (ORP) values by standing times. The condition of hydrogen-water was the same as B. Measurements for each material of containers were performed more than three times and typically the mean values were plotted
