苯是已知的人类致癌物质中研究最多的物质之一。它会导致人类的白血病,以及大鼠和小鼠的各种实体肿瘤。几十年来对苯代谢、药代动力学、细胞毒性、遗传毒性和体内和体外致癌性的研究开始集中在关于苯毒性和致癌性最可能的生物学机制的一小部分重叠的假说上。尽管仍有惊喜的空间,但苯如何发挥其多重影响这一谜团的最终答案似乎将包括对目前的一个或多个假说的阐述和扩展。本文综述了苯对健康的影响和生物学,展示了新陈代谢和细胞毒性的各个方面如何与遗传毒性和非遗传毒性效应相结合,以帮助解释苯可能导致癌症的原因。它的目标是:(I)介绍详细的苯癌风险定量剂量-反应模型所需的定性生物学背景;以及(Ii)综述一个迅速发展的研究领域,该领域有望在未来十年对几种化学品--苯,可能还有苯酚、儿茶酚和其他羟基环烃--的毒性和致癌机制产生基本的见解。
Benzene is one of the best studied of the known human carcinogens. It causes leukemia in humans and a variety of solid tumors in rats and mice. Decades of research on benzene metabolism, pharmacokinetics, cytotoxicity, genotoxicity, and carcinogenicity in vivo and in vitro are starting to converge on a small set of overlapping hypotheses about the most probable biological mechanisms of benzene toxicity and carcinogenicity. Although there is still room for surprises, it seems likely that the ultimate answer to the mystery of how benzene exerts its multiple effects will consist of elaborations and extensions of one or more of the current hypotheses. This paper reviews benzene health effects and biology, showing how various aspects of metabolism and cytotoxicity fit together with genotoxic and nongenotoxic effects to help explain how benzene may cause cancer. Its goals are: (i) to introduce the qualitative biological background needed for detailed quantitative dose-response modeling of benzene cancer risks; and (ii) to survey a rapidly evolving area of research that shows promise of producing fundamental insights into the mechanisms of toxicity and carcinogenesis for several chemicals--benzene and perhaps phenols, catechols, and other hydroxylated ring hydrocarbons--in the decade ahead.
