Exposure to rare earth elements (REY) in the environment can lead to adverse effects on human health. Industrial activities unintentionally produce fly ash, and a small fraction of fly ash that remains uncaptured by air pollution control devices can enter the atmosphere and contribute as a primary source of airborne fine particle matter (PM). The occurrence of REY in industrial sourced fine PM affects the environment and human health. There is relatively minimal information regarding the human health hazards and biological effects of REY in fine PM produced during industrial activities, especially for non-occupational people. In addition, REY are powerful source-specific tracers for airborne PM from industries. Therefore, relevant research on REY in fine PM from industrial processes not only contributes to understanding and preventing environmental pollution but can also provide basic data for reducing human exposure. This paper provides an overview of the research status and latest advances in various industrial processes, especially their distribution characteristics, influencing factors, tracer application, and biological effects of REY in fine PM from coal-fired power plants. We also suggest future research directions in light of existing problems.
暴露在环境中的稀土元素（REY）可能会对人类健康产生不良影响。工业活动会无意产生飞灰，而一小部分未被空气污染控制设备捕获的飞灰会进入大气，成为空气中细颗粒物（PM）的主要来源。工业来源的细 PM 中 REY 的存在会影响环境和人类健康。关于工业活动产生的细 PM 中 REY 对非职业人群的健康危害和生物效应的信息相对较少。此外，REY 是工业空气中细颗粒物的有力特定来源示踪剂。因此，对工业过程中细 PM 中 REY 的相关研究不仅有助于了解和预防环境污染，还可为减少人类暴露提供基础数据。本文综述了各种工业过程中 REY 的研究现状和最新进展，特别是燃煤电厂中 REY 在细 PM 中的分布特征、影响因素、示踪剂应用和生物效应。我们还根据现有问题提出了未来的研究方向。
