Abstract: The current review reflects recent advances in photochemistry of humic substances in natural waters. Mechanisms and kinetic factors that control the photochemical processes of humic substances are discussed with emphasis on the formation of reactive oxygen species(ROS) and their reaction pathways. The environmental significance of the photochemistry of humic substances in natural waters is summarized. The authors provide a perspective of future study emphasis in this field of environmental chemistry.

Key words: humic substances, photochemistry, reactive oxygen species
