| Use of several radical trapping techniques including benzoic acid, nitroxide/DMSO, and nitroxide/methane methods have been employed to quantify the extent of photo-reactivity under solar simulated conditions. Preliminary evidence supports photochemical formation of highly reactive hydroxyl radical from the reaction of chlorinated quinone pesticides with water. Compounds of interest include the chlorinated pesticides, dichlone (2,3-dichloro-1,4-napthoquinone) and chloranil (tetrachloro-1,4-benzoquinone). Rates of photochemically produced hydroxyl radical will be presented as well as proposed degradation products for these pesticides. |
