N2 - Reactivity of the singlet oxygen (SO), which is assumed to be one of the important oxidizers in natural waters, towards to a set of persistent herbicides, was measured for the first time using time resolved luminescence technique. It was observed that rate constants of SO reactions with the majority of studied herbicides are less than 106 M−1s−1 allowing to conclude about negligible participation of SO in oxidation of the compounds in natural waters.
