Indirect Photochemistry in Sunlit Surface Waters: Photoinduced Production of Reactive Transient Species

This paper gives an overview of the main reactive transient species that are produced in surface waters by sunlight illumination of photoactive molecules (photosensitizers), such as nitrate, nitrite, and chromophoric dissolved organic matter (CDOM). The main transients ((OH)-O-center dot, CO3-center dot, O-1(2), and CDOM triplet states) are involved in the indirect phototransformation of a very wide range of persistent organic pollutants in surface waters.
