摘要
氟和钼是广泛存在于表生环境中的人体必需微量元素,但过量摄入会影响人体健康,甚至会诱发地方性疾病。西南燃煤型地方病区部分煤炭和土壤中存在氟、钼富集的情况。本文系统介绍了氟和钼的元素地球化学行为特征和健康危害效应,综述了氟和钼在西南地区高氟高钼地质背景的燃煤型地方病区煤炭和土壤中的分布特征和赋存形态,分析了燃煤型地方病区煤炭开采、堆放和燃烧过程中氟和钼的迁移释放规律。研究认识对于高氟高钼地区氟、钼暴露及防控具有重要的科学价值和实际指导意义。
Fluoride( F) and molybdenum( Mo),are the essential trace elements for humans and are widely occurred in the environment. However,long-term exposure and excessive intake of F and Mo may lead to endemic diseases for human health. This paper systematically introduces the geochemical characteristics and health effects of F and Mo,and reviews the research progress about the distribution and occurrence of these two trace elements in coals and soils in the regions with high geological background of F and Mo in the coal-combustion related endemic fluorosis areas in southwest China. This paper also summarizes the migration and release of F and Mo from coal mining,stacking and burning processes in the high F and Mo geological background areas. This study has an important significance for scientific prevention for excessive exposure of F and Mo,as well as reducing health risks of F and Mo in coal-burning related fluorosis areas.
