  • Title: Studies on photochemical reactions of air pollutants. XII. Photochemical epoxidation of aldrin with suspended particulates in air.
    Author: Nojima K, Isogami C, Itoh H, Kawaguchi A.
    Journal: Biol Pharm Bull; 1994 Jun; 17(6):815-8. PubMed ID: 7951144.
    Abstract:
    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.
