Studies on photochemical reactions of air pollutants. XII. Photochemical epoxidation of aldrin with suspended particulates in air.
Suspended particulates collected in Yokohama, Japan over various 24-h periods were found to cause the photochemical epoxidation of aldrin to dieldrin in good yield. trans-Stilbene did not undergo the epoxidation. Upon irradiation of aldrin together with the suspended particulates in quasi-air consisting of 18O2. 100% incorporation of 18O into dieldrin was obtained. Thus, the oxygen atom in dieldrin originated not from the particulates, but from oxygen in air.
