These results are significant because PAH diol epoxides react readily with DNA, induce mutations, and are considered to be ultimate carcinogens of multiple PAH in cigarette smoke.
这些结果具有重要意义,因为多环芳烃二醇环氧化物极易与DNA反应,进而导致变异,因此被视为香烟烟雾中所含多种多环芳烃中最重要的致癌物质。
The catalysts are easy to prepare and use, they are easy to recover and reuse, and they convert olefins to epoxides in good yields with high selectivity.
催化剂容易制备和使用,易于回收并再用,且它们能以很好的收率高选择性地 将烯烃转化成环氧化物。
