摘　　要：己烯雌酚(DES)是一种活泼的环境雌激素。利用流动池脉冲辐解手段对其活性瞬态粒子的动力学特性作了初步研究,发现己烯雌酚自由基的苯环间双键可能是羟自由基优先进攻破坏的一个位点。该化合物对高能电子束非常敏感,通过自由基机理被降解。研究结果对DES环境降解机理和生物毒理,对探索解毒、环境修复等,具有一定的指导意义。Diethylstilbestrol (DBS) is one of the most active environment estrogens. In this paper pulse radiolysis was carried out to study dynamic characteristics of active transient species of DBS. The double bond between the benzene rings was supposed to be one of sites attacked by hydroxyl radicals. DBS was rather sensitive to high-energy electron beam and their radicals can be easily degraded easily. The works will be of help for us to study degrading mechanisms and biological effects of DBS, and to explore environment-repairing ways against DBS.
