Hydrogen Nanobubble Water: A Good Assistant for Improving the Water Environment and Agricultural Production

Abstract

Hydrogen nanobubble water (HNW) is an emerging technique in the field of environment and agriculture that is attracting more attention due to its eminent characteristic. HNW exhibits a higher solution stagnation rate with a longer existence in water than molecular hydrogen, which ensures its practical usage. In this Viewpoint, the properties and applications of HNW are discussed. HNW, acting as an antioxidant, effectively eliminates reactive oxygen species and counteracts Cu and Cd stress; HNW also increases crop growth, enhances crops quality, and improves transportation and storage processes. On the basis of the advantages of HNW, we recommend focusing on the potential functions of HNW and broadening its wider applications in environment and agriculture.

“…Furthermore, hydrogen-rich water positively affects the abundance of flavor components such as esters (e.g., furanone derivative relative concentrations increased 10.8- and 13.2-fold in strawberries irrigated with experimental treatments, respectively) and soluble sugars (e.g., glucose, fructose, and sucrose) in fruits, including strawberries, as well as in postharvest horticultural products [ 12 , 15 ]. However, the applicability of hydrogen-rich water in improving agricultural productivity is hindered by the low solubility and strong diffusivity of hydrogen [ 17 ].…”
