Abstract

we measured concentration of reactive oxygen species in waters of 8 rivers located in Kanto District to Kyushu District, Japan. Steady state concentration, photochemical formation rate and half-life were determined. Peroxides such as hydrogen peroxide and lipid peroxides were also measured. Soureces and sinks of the reactive oxygen spceis in river water were elucidated and discussed about their roles in mineralization and redox reactions of dissoled organic matter.
