Photochemical oxidation of terbufos

We studied the photochemical oxidation of an organophosphorus pesticide, terbufos, in surface waters because its oxidation products are of concern. Terbufos sulfoxide and terbufos sulfone have toxicities for aquatic organisms similar to those of the parent compound. We measured a photolysis rate constant under natural sunlight conditions in distilled water of 0.68 ± 0.17/h near Clemson, South Carolina, USA. Actinometer studies resulted in a mean reaction quantum yield for terbufos of 5.8 X 10-3. The measured half- life of 64 min is considerably faster than any of the other chemical or biochemical oxidation half-lives in in soil or hydrolysis half-lives reported in the literature. Photolysis should be considered in evaluating the risk of terbufos to surface waters and aquatic organisms.
