枯烯（异丙苯）和吡啶在天然沃茨稀溶液中的光氧化反应生成的产物具有与烷基过氧（RO 2 O）和羟基（HO O）自由基反应的特征。根据产物的形成速率，RO 2 ⋅和HO⋅的平均浓度估计分别约为10- 9和10- 17摩尔/升。RO 2的浓度足够大，对于某些类别的活性化学品，氧化可能是天然沃茨中的重要过程。
Photooxidation of cumene (isopropylbenzene) and pyridine in dilute solution in natural waters gives products characteristic of reactions with alkylperoxy (RO2⋅) and hydroxyl (HO⋅) radicals. On the basis of the rates of formation of the products, the average concentrations of RO2⋅ and HO⋅ are estimated to be about 10-9and 10-17mole per liter, respectively. The concentration of RO2⋅ is large enough that, for some classes of reactive chemicals, oxidation can be an important process in natural waters.
