【Abstract】 The mechanisms and kinetic factors of photochemical formation of reactive oxygen species, such as hydroxyl radicals, from the photolysis of nitrite and nitrate in natural water are firstly reviewed. Since the reactive intermediates involved may induce further reactions of organic compounds in water, the implications of these processes in aquatic environment are then discussed. Finally, a perspective of future studies in the field of environmental chemistry is provided.更多还原
