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.
在日本横滨不同24小时时间段收集的悬浮颗粒物被发现能使艾氏剂光化学环氧化生成狄氏剂,产率良好。反式芪未发生环氧化反应。在由18O2组成的准空气中,将艾氏剂与悬浮颗粒物一起照射时,狄氏剂中100%掺入了18O。因此,狄氏剂中的氧原子并非来自颗粒物,而是来自空气中的氧。
