正在制定化学混合物、综合暴露和累积暴露的风险评估程序,但科学数据库需要相当大的扩展。特别是,缺乏关于如何监测复杂暴露的影响的知识,而且关于生物监测复杂暴露的综述很少。在这篇综述中,我们总结了已经开发和使用的生物监测技术的文章。大多数例子描述了生物监测效应的技术,这种技术可以检测到许多化学应激源引起的早期变化,并有可能加速数据收集。一些重点放在通过表观遗传机制起作用的内分泌干扰物和致癌物上。确凿的证据表明,这些化学物质可以相互作用,甚至产生协同效应。它们可能在敏感的时间窗口内起作用,在流行病学研究中对它们的影响进行生物监测是一项具有挑战性的任务。
Procedures for risk assessment of chemical mixtures, combined and cumulative exposures are under development, but the scientific database needs considerable expansion. In particular, there is a lack of knowledge on how to monitor effects of complex exposures, and there are few reviews on biomonitoring complex exposures. In this review we summarize articles in which biomonitoring techniques have been developed and used. Most examples describe techniques for biomonitoring effects which may detect early changes induced by many chemical stressors and which have the potential to accelerate data gathering. Some emphasis is put on endocrine disrupters acting via epigenetic mechanisms and on carcinogens. Solid evidence shows that these groups of chemicals can interact and even produce synergistic effects. They may act during sensitive time windows and biomonitoring their effects in epidemiological studies is a challenging task.
