利用生物标志物高灵敏的特性 ,可以直接测量人群长期低剂量的暴露水平及其效应水平 ,能够较准确地估计生物标志物水平与特定危险性之间的关系 ,这方面的研究尚属起步阶段 ,但在环境健康危险度评价中具有很好的发展前景。对生物标志物的选择 ,其在低剂量致癌物暴露危险度评价中的作用 ,评价方法或途径及存在的问题进行了总结。 By using the highly sensitive characteristics of biomarkers, the long-term low-dose exposure levels and their effect levels can be directly measured, and the relationship between biomarker levels and specific risks can be estimated more accurately. This aspect of research is still in its infancy. , but it has good prospects for development in the assessment of environmental health risks. The selection of biomarkers, their role in the assessment of exposure risk of low-dose carcinogens, evaluation methods or approaches and existing problems were summarized.
